Guys when i enter any interior like any business interiors,hangar,or the garages and the casino interrior too in freemode and in heist too (when in the vault my game lagged that much that even with 2.50mins i could only get 2 crates of gold alone)BUT NOT ALL INTERIORS IDK for somereason dont lag like in doomsday all the interiors in ACT-3 before the interior where we hack the servers it is smooth but as i enter the room where we hack the servers there it starts lagging
when i m in storymode my game runs realllllly smooth like around 40-50 FPS
hardware problem--- nope because in storymode it runns like butter and in online as i enter a interior it starts lagging to a point where i can barely control the charecter and when in missions which take place in some interiors i cant even properly shoot ..
CPU usage--- nope GTA 5 takes around 70-80 in story mode but it runs smoothly in online the same but in interiors it starts lagging (there r no other process running while i play GTA5 i turn off all AV components that can take high CPU usage in services permanently) i searched in youtube found nothing
anyone know how to fix that

So as you all know the game GTA V GTA V has a mode called GTA Online and in online there is a DLC called the Diamond Casino Heist... Now it is self explanatory. Rob a Casino. But heres the catch, after you have bought your arcade, done your preps and are onto the finale, you go into the vault and you have to hack into these keypads... now problem is, not many players can get their head around it and so I was one of them and now i dont even have to look at the fingerprint and can hack 4 prints in a matter if 10 seconds... Wondering how? Well rather than spending 500,000 GTA$ to buy a fingerprint scanner practice in your arcade, you csn practice here https://johan.li/gta-online/fingerprint-scanner-simulator and it is pretty simple and after some attemps you can get the hang of it Hope it helps and also sub to my YouTube channel Abz Animations (I do casino heist videos) and yeah...

PS4 / Xbox One
This works similarly to this method which is on PC.
Most of you probably already know the whole cancel while inside the Casino part, if so skip to Step 6.
Video Instructions

Instructions:

Go to your Arcade and start the “Vault Contents” Prep
Go to the guard and hack his phone
Go to the Casino and identify the vault contents
If it isn’t the Vault Content that you want then call Lester (while still inside the Casino) and select the option that says “Cancel The Diamond Casino Heist”
Go back to your Arcade

6 Change your spawn location to “Arcade” or “Last Location”

Go to the prep board and pay to set up the heist again

At this point your vault contents may have changed to what you wanted.
If it hasn’t changed to what you want then:

Disconnect from the Internet, this should force you into Story Mode. On PS4 go to Network Settings and uncheck “Connect to Internet”. You could also close your game.
Load back into GTA Online (Invite Only loads faster)
Your prep board should be blank and you should now have the option to set it up again. Pay to set it up

Ideally your vault contents would of changed to what you want, if not then repeat steps 8, 9 and 10 until you get your desired vault content.
In my opinion, this is better than repeatedly doing the entire mission if you don’t get the vault contents you want when returning to the Arcade.

–This is a guide mostly for new players. I'm sure anyone whose been playing this game for a few years knows all this–
I started playing GTA online roughly two months ago and I already have practically everything I wanted, just from grinding the casino heist over and over again.
It can get tedious, sure, but so can everything else in life. You just have to have a positive mindset and think of the reward at the end– all the jets, planes, cars, bikes, clothes etc...! PLUS I personally find the preps a lot more enjoyable than doing sell missions for the bunker or doing import/export over and over.
I'm doing this on mobile, so please excuse any formatting errors :)
Note– doing this with two people is always the most optimal way to make money. Give yourself a huge cut. You deserve it for doing all the preps.
•step one: buy an arcade in Las Santos. Don't buy the one in Paleto Bay because that long drive to the casino will drive you crazy if you do it enough.
•step two: do all your prep works/setups in an invite only session. Trust me, it makes life so much easier when you're not bring chased by an oppressor all the time.
•step three: you can shuffle the contents you get in the vault. –NOTE THAT YOU CAN ONLY DO THIS IF YOU HAVE ALREADY COMPLETED ALL THREE HEIST APPROACHES–. YOU DO NOT WANT CASH. Art is better than gold (in my opinion) purely because it's very easy to do with two people... meaning you can keep a much bigger cut for yourself. Gold is awesome, but I'll talk about that in a bit.
•step three (b): to shuffle the vault contents and try to get something other than cash; simply do the vault contents prep. When you go to the casino and access the security camera feed, find the camera which reveals what's inside the vault. If you get art or gold, perfect! If you get cash, identify the target and wait for Lester to stop talking. Back out of the camera and then call Lester. Cancel the heist BEFORE you leave the casino. Leave the casino and go to your arcade. You will then have to pay another 25,000 to setup the heist again. When you pay, you will notice that a target has already been identified and there's a chance that this target will be different to what you already had. It's random so you may have to do it again. If you get cash again, go outside, cancel the heist again, restart your system, setup the heist again and repeat the previous steps until you get a better target than cash :)
•step four: always choose either aggressive or the Gruppe Sechs approach. Silent and sneaky with randoms is a nightmare abs it's not worth the frustration. Only do silent and sneaky with friends or people with mics
•step five: in order to even unlock the Gruppe Sechs approach, you have to first do the scoping out prep. Go to the sewer tunnel entrance that's closest to the casino. Go down the tunnel and look to your right. You will see a large semi-circular shaped get made of steel poles. Take a picture of it and send it to Lester. This will unlock the group Sechs approach!
•step five (b): always pick the cheapest gunman, the cheapest car guy and the best hacker. The best hacker you can get is AVI and to unlock him, you have to destroy all the signal jammers around the city.
•step six: there are optional preps. Some you can always skip and some you should absolutely do. You should ALWAYS get the level 2 keycards because if not, you will have to deal with that awful hacking minigame involving circles. Save yourself the headache of dealing with it and always do that prep. There's no point in getting the masks for any approach.
•step six (b): If you are doing the aggressive approach, I would highly recommend doing the enhanced body armour prep, Duggan's shipments and the level 2 keycard prep. You can skip everything else that isn't mandatory. The enhanced body armour will make your life so much easier... trust me. Doing Duggan Shipments and getting all 10 will makes the guards extremely easy to kill and will give them weak weapons.
step six (c): for the Gruppe Sechs approach, I would recommend doing the level two keycards and getting the exit disguise. I personally recommend going for the firefighter outfits because they're easier to get OR if you have the time, you can collect 54 playing cards, unlock the high roller outfits and you can use those as an exit disguise instead. They'll be permanently unlocked, meaning you can skip the exit disguise in future if you have it. Those are really the only optional preps you need. Patrol routes might seem important, but it's not.
step seven: when you're finished in the vault, always exit through the staff entrance. This will leave you in a position with the least amount of noose and the best position to escape from and to get to your getaway vehicles.
step eight: get in any vehicle you can find. Doesn't have to be your getaway vehicles. Drive to the police station that's near the casino, climb to the roof and get in the helicopter. It's the fastest way to your destination and to lose the cops. To see a tutorial of how to do this, there a tonne of guides on YouTube :)
step nine: you're done! You just completed the heist. Now you have to wait about 5 to 10 minutes to receive a call or text from Lester, suggesting you to do the heist again. Now, just do all steps again and you can easily make 2-3 million in about three or four hours.
If I'm missing anything, please let me know :)

Diamond Casino Guide:
So you decided that you wanna rob a casino, great! The Diamond Casino Heist is one of the best ways to earn money, but you're wondering, how do I get started? Well, you're in luck! This guide is going to teach you the ways to get the best out of the Diamond Casino Heist!
Step 1: Arcade
Alright to get started, you’re going to have to own an arcade. Now, it may seem better to go for the arcades on the top of the map to save yourself some cash, however, this will make all the preps much harder, as most of them take place in LS or Sandy Shores.
The best arcade locations are 8-bit ($2,530,000, located in Vinewood) and Videogeddon ($1,875,000, La Mesa). When buying your arcade, none of the upgrades are necessary, as most of them are cosmetic. You’ll have to complete a quick arcade setup mission to access the basement where the diamond casino heist planning board is located.
Step 1.5: Arcade Income
While this isn’t related to the diamond casino heist, I thought I would put this in there. The arcade generates income based on how many games you have, going up to 5k per in-game day (48 min). The game doesn't matter, so you can just buy the cheapest one (Monkey’s Paradise, $90,000) and fill up your arcade with it.
Step 2: Scope out casino
After you’ve finished watching Lester scribble a big mess over the whiteboard, you’ll be able to start the casino heist. Normally, you’ll have to pay a setup cost of 25k, but since it’s your first time doing it, it’ll be free. After you’ve confirmed that you want to start the casino heist, you’ll need to finish the scope out mission. For the scope out mission, you’ll need to take a variety of pictures for Lester in order to unlock entrances for the heist. A full guide is linked here but I’ll sum up the most important ones.

Staff Lobby: This entrance is arguably the best entrance for the Silent and Sneaky approach. It gives you easy access to the control room where you can get the daily vault easily. It is also the best exit for most approaches as not many guards patrol it. The staff lobby should be around the back of the casino and should look like a white door behind some yellow bollards.
Security Tunnel: By scoping out this entrance, it gives you the ability to enter the casino as a Gruppe Sechs team for the Big Con. This entrance is the best if not one of the best approaches to the casino heist. The disguise will allow you to go straight to the vault undetected and back up, however, you will be detected when going back out of the casino on the casino access floor, so I would suggest getting some exit disguises to make your escape easier. The security tunnel should look like a big metal garage door with a security camera watching over it under the racetrack.
Sewers: The sewers allow you to burrow down right into the vault access floor giving you easy access as you are right next to the vault mantrap. The sewer exit, however, is only available in the aggressive approach.
Roof Terrace: At first glance, the roof terrace may seem like a horrible entrance/exit, however as it turns out, the roof terrace is actually a contender for one of the best aggressive exits. By taking the roof terrace, you can shoot down the guards at the racetrack while they're not being able to shoot back and then parachute down.

You’ll only need to do this mission once, and it will be completed for all future casino heists.
Step 3: Vault Contents
The vault contents mission is pretty easy. You’ll be given the rough location of a Duggan security guard, once you find him, you can either hack him, which can take some time but you won’t get the cops on you if you do it right, or you can kill him and grab the phone, which will save you some time but you’ll need to lose the cops before you can enter the casino.
After you’ve entered the casino, you’ll need to bring out the sightseer app on your phone to find a wifi signal. After you’ve located the wifi signal, you’ll need to figure out the vault contents. Beware that you only have a limited time to do this (2 min).
Since it’s probably your first time, I would recommend that you go through every camera to scope out each POI. The target will be cash since it’s your first time, which has a payout of 2.1 mil on normal. The first time will always be cash (payout of $2,115,000 on normal), but if it’s not your first time, the targets can be either cash, artwork (payout of $2,350,000 on normal) or gold (payout of $2,585,000 on normal).
There is a 4th target, which is diamonds (payout of $3,257,100 on normal) however this vault content is only available for special occasions and has been removed from the vault contents.
If you do the heist on hard by doing the same approach after you’ve done another one, the payout will be 10% larger. If you’ve completed all 3 approaches to the heist, you can cancel the heist which can be helpful if you’ve got a bad target. Link to this is here.
Step 4: Selecting your approach
Once you’ve finished the vault contents mission, you’ll be able to select your approach.
There are 3 approaches to the diamond casino heist. Silent and Sneaky, The Big Con and Aggressive.
For beginners, I would recommend alternating between Big Con and Aggressive, because those are the easiest ones. For Big Con, choose the Gruppe Sechs disguise for the easiest entry. Aggressive is good for newer players however it does end up in a lot of money loss. After you’ve got the gist of it, alternate to doing Silent and Sneaky in place of aggressive for a bigger payout.
Step 5: Selecting your support crew
After you’ve selected your approach, you’ll need to select your support crew before you can do any of the prep missions.
Selecting your support crew is very simple. You’ll need a gunman to source guns, a driver to source cars, and a hacker to delay the nerve agent inside the vault.
Selecting your support crew depends on the approach and target in the vault. For Big Con, SnS, any target EXCEPT for art, you’ll want the worst gunman (Karl Abolaji, take his Micro SMG on big con, heavy revolver on aggressive and on SnS the choice is up to you), the worst driver (Karim Denz, take his sentinel classic) and the best hacker available to you, for most people, this will be Paige Harris (unlocked when the Terrorbyte is purchased, gives 3:25 in the vault when undetected and 2:23 detected).
For aggressive, you’ll still want to have the worst driver and best hacker, however, the gunman is up to you since you’ll be using guns a lot. I normally go with Charlie Reed (unlocked when purchasing a hangar), he takes a 7% cut (2% more than Karl) and gives you an assault SMG, however, you can get by with Karl, as every gunman gives you an SMG to go along with another weapon, which is still a perfectly fine weapon.
For Big Con, SnS and the target is Art, if you and your heist partner can both hack very well, you can get by with Yohan Blair (takes a 5% cut and gives you 2:51 in the vault if you are undetected and 2:01 if you are).
Step 5.5: Secret heist crew members
There are 2 hidden heist crew members that can’t be unlocked by purchasing a business like most heist crew members. There 2 are Patrick McReary and Avi Schwartzman. Patrick McReary is a gunman who takes an 8% cut and gives the choice a Combat MG or an Assault Shotgun in aggressive. Avi Schwartzman is a hacker that takes a 10% cut and gives 3:30 undetected in the vault and gives 2:22 if you are detected. To unlock Patrick, he spawns as a random event around the map. He spawns in a police car that you will need to hijack. A guide is linked here. To unlock Avi, you’ll need to destroy 50 signal jammers that are located around the map. A guide is linked here.
Step 6: Prep Missions
Now that you’ve selected your support crew, you’ll be presented with a plethora of prep missions. Some mandatory and some optional. To complete these missions, I suggest that you use a Kuruma, Buzzard, or Oppressor Mk2 to make your life easier. In some prep missions, you will not be able to call Lester, so be prepared. All of the missions can be done solo but it makes it easier if you have a friend with you to help you out.
Now onto the optional prep missions. Optional prep missions, are, as the name suggests, optional. The optional prep you should do depends on the approach. If you own a penthouse and have completed all of the missions, you will gain access to the security intel mission. It’s very easy to complete and you will only need to do it once. A nice trick is that the gauntlet actually spawns when you start the mission, not when the cutscene is triggered, so you can just shoot the driver and take the gauntlet. A guide will be linked below.
Let’s start with Silent and Sneaky. For Silent and Sneaky, the optional prep missions depend on your skill level. If you’re an experienced player, you don’t need to do much, only level 2 security passes. Power drills you can do if you think you have enough time. However, if you are a very new player, I’d recommend that you do patrol routes, Duggan shipments (you only need to destroy 3 to get rid of their bulletproof helmets), level 2 security passes, emp device and infiltration suits and power drills if you think you have enough time. If you do all these, the heist should be a breeze.
Going onto the Big Con, if you’re doing Gruppe Sechs, you don't need to do much. You only need to go through one door if you exit out the staff door, so you can decide if you want to do level 2 security passes or not. Patrol routes do make things easier, however are not necessary. Again, only do power drills if you think you have enough time. Make sure you do exit disguises. Noose and firefighter are exactly the same, so do firefighters since it has an easier mission.
For aggressive, again, patrol routes make it easier but are never necessary. Make sure to do Duggan shipments. You can solo it, but it will be much easier with another person. If you don’t get them all you can just close the game and you’ll be able to do the mission again. Reinforced armor allows you to take more damage, so I would recommend it even if it makes you slower. Be sure to also do boring machine as it allows you to enter through the sewers. Make sure to also do level 2 security passes unless you really like hacking doors.
Step 7: Finding people to play with
Now that you’ve completed all your required prep missions, you need some people to play with. If you don’t have any friends to play with, I recommend checking out HeistTeams or the GTAO Discord LFG Channels to find people to play with. Make sure to have good communication between your teammates otherwise the heist will be in chaos.
Step 8: Completing the heist
Now that you’ve got a solid heist crew waiting to grab all of that sweet loot out of the casino’s vault, you’ll be able to start the heist. If you're doing aggressive, the plan is pretty simple, shoot your way in, grab the loot, then shoot your way out. The easiest entry for aggressive is sewers, and the easiest exit is the eastern roof terrace. If you exit through the staff lobby, you’ll get shot a ton when going over the racetrack, however, if you exit through the roof terrace, you can shoot the guys behind the stones on the racetrack then safely parachute down.
For The Big Con, I’m going to assume you’re doing the Gruppe Sechs approach. By doing the Gruppe Sechs approach, you can pretty much waltz into the vault and back out of it, just be careful that this has some limitations. When going back up the stairwell/elevator to the casino access floor, the guards will have checked the vault and know it’s been robbed, so you disguise ain't gonna work anymore. I strongly suggest getting exit disguises, as they will greatly help your escape. The easiest exit for this is the staff lobby.
For SnS, I’m not really going to go into too much detail here because there’s a full video linked below. What I will talk about is when to use the emp (If you did the prep mission). I recommend emp’ing when you’re at the vault access floor, allowing you to waltz into the mantrap, or when you're coming back up to the casino access floor and are in the mantrap. Be warned that if you decide to get the daily vault when you trigger the emp, the emp’s timer will run out before you can get to your exit, so plan ahead. The easiest entrance for this is the staff lobby and the easiest exit is also the staff lobby.
Tips and tricks to complete the heist

If you are disguised, do not bump into any of the guards. They will detect you and start shooting.
In the control room, there is a button that you can press to open the door to the daily vault. One person has to hold the button while the other goes in and grabs the cash. This can be done with any approach.
Running and jumping is faster than just running normally, use this to your advantage while inside the vault.
Running in first person is actually faster than 3rd, so use this to your advantage when trying to knock out guards.
Don’t bother trying to escape the cops by hiding in an alley or something, either take your car into the sewers down by the LS river or take the heli that usually spawns on top of the police station. The sewers will result in you losing less money, however will be much slower. I will link both of these methods below in the useful media section.
Normally when exiting the casino from the staff lobby without any disguise, you’ll need to knock out a guard to the left of the swat fan to your right, before hugging the race track wall and then dropping down. I have found that sometimes if you run, the guard will hear you and detect you, causing you to get shot at. To prevent this, walk up to him making sure you stay out of his FOV then knock him out.
You walk much faster in the casino if you are in first person, making the vault contents mission much easier.
In prep missions, you can change any accessory (glasses, hat, ect.) to lose 1 star which is useful on missions where you can’t call Lester to remove your wanted level.
On some missions, you can lose the cops by entering your Terrorbyte/MOC/Avenger.
On some missions, you can lose the cops if you accept Lester’s apartment heist invite. This only works if you have a heist active.
In the hacking device mission where you have to infiltrate the FIB building, you walk a lot faster if you aim down sights on any gun, however, if you go into any agent’s LOS you will get detected instantly, so be careful when using this trick.
You can upgrade your getaway vehicles in the arcade by getting in them and pressing the button shown on the prompt that appears on the top left.

Where to begin with.. Ok, so, I started playing GTA again almost 2 weeks ago. I classify myself as an old school gta roamer who mostly does missions and heists...and has never been into race and stunts stuffs. Most of the time I am comfortable playing contact missions and heists with random people, and from time to time I would find someone has similar play style as mine and we would add each other as friend and do more missions together in the future.
Shortly after I started playing GTAO again after an almost 2-year break, I met this guy called Xhak-571 in a Gerald's Last Play. He was level 20, and I was around 250. Near the end of the mission he asked if anyone wanted to do a heist, of course I agreed immediately (he was new but certainly he knew what he was doing, judging from the way he played); and then we went through the entire Doomsday Series together. And Diamond Casino Heists after that, all 3 approaches.
I must say I helped him a lot, I'd always set my payout to 15% because it's not like I need the money, and he would definitely want more than I do, and so we kept playing to the point he has enough in-game cash to set up his own businesses including Bunker, Coke and Vehicle Cargo.
I also told him about snacks and body armors early on to get through tougher sections of the heists.
I sent him a fingerprint cheat sheet for hacking the padlocks in Casino Vault.
I taught him how to suspend GTA to get his solo public lobby.
I help him with his selling missions.
I gave him a helicopter lift whenever he needed to travel across the map (his Bunker is in Paleto Bay).
He's clearly into the game, that eventually he asked 2 other real life friends of his to buy the game and all play together. And we were in such good term with each other (by online gaming standard): always greeting, always laughing when funny stuffs happened, saying thanks when helped, and saying goodnight before logging off. All was good, until today.
After jumping into the game in the afternoon, I got auto invited into his heist finale. I was surprised, as the day before he was asking if he could do the finale with only two of his friends, so they can get more GTA$, and I happily accepted and left the launch screen. So I asked 'Did you invited me?', and after half a minute I saw the following messages in the image, from him and his friend. They are Italian-speakers and know that I don't understand any of this. Right before I could type anything, I was kicked out of the launch screen. I went to try to message them on socialclub, and guess what, I was blocked, by him, and every single one of his friends. I was super confused and thought it was an issue with R* servers, so I tried instagram, since Xhak-571 asked for my instagram a few days ago. He was online, and I messaged him what was going on, then he instantly blocked me again as his account became 'does not exist' right after I sent the text.
It's now clear that they all blocked me for some reason, but I'll never know why for sure.
I do however have one theory, it's that one of them checked my instagram, saw my pictures and found out I am Asian, and MAYBE they are some racist dicks and don't want anything to do with me anymore.
Now, I really thought it was far fetched, but my best friend (who is Italian) told me it's actually the likeliest explanation.
I was shocked, but now am now pissed, and deeply sad, as the moment I thought I found some people to play gta with, this kind of thing happens.
If you reached this far in the post, thank you for listening to my rant.

It is my first time composing a guide like this for GTA Online. So any criticism or suggestion is welcome! I really wish this can be helpful. There is a ton of wiki about it but I am just going to refine them into my own words.
Btw, this guide is not for people who is already a veteran. Casino heist is the easiest way to make a quick fortune so far because you can join a finale through your phone (although there is a cool down time between each). And you probably won't find any extreme method to maximize payout such as glitch. The main purpose of this article is help people have fun.
Scope Out
This is something you do once and for all. So there is no reason why you don't scope out all access points and P.O.I.. You can launch this mission every time when you are hosting the heist, but can only be done before selecting approach. There is plenty of Youtube videos about where to find them such as this.
Vault Content
Just to to the observatory and find 2 guys chatting. Sometimes they are at the front door but most of the time they are on the left side of building. One guy with a baseball cap and the other "bigger" guy with a cowboy hat. Start hacking through securoserv app while walk along with the guard while he takes a phone call. Don't run into or kill him cuz that will get cops on you. Hacking into security camera is easy so let's skip that (sometimes the Wi-Fi spot is in the restroom).
Casino Model & Door Security & Vault Door
All of them are complete waste of money. Casino model is purely decorative. If you want to practice hacking, just ask teammates or friends nicely to give you a shot in the vault or watch Youtube. And there is no need to practice drilling vault door because you are not on a time limit.
Before we jump into approaches, there is a prep mission called "Security Intel". It gives you all the camera vision without having to getting close to a camera. You will need to complete all Diamond Casino & Resort story missions as the host in order to unlock this mission. Once it's done, you don't have to do it again. The camera intel stays with you. JUST DO IT FOR VINCENT'S SAKE.
Prep Board
Next, I'm gonna tell you what each prep mission means and which optional missions are actually worth doing imo.

Silent & Sneaky

Gunner: Hire the cheapest guy because you are not supposed to exchange fire anyway. There are two loadouts to choose from and both works great.
Driver: Hire the cheapest guy because you don't need his help at all. This role is a fucking free rider and you will see why later. I always source Übermacht Sentinel Classic because it goes fast and handles the best. It matters in setup mission.
Hacker: Hire Paige because she gives you more time in the vault. It's worth the investment. If you have Avi unlocked you can try him to. He takes 1% more cut but gives you 5 seconds more time in the vault when exposed and 3 more seconds when undetected. It's up to you whether he is worth it. To unlock Avi as hacker, you need to destroy all 50 signal jammers around the map in free mode. Youtube video guide is here.
Patrol routes: It makes more enemies visible on mini map. I always do it but if you feel comfortable to skip it, I respect that.
Duggan shipments: MUST DO! Because you are supposed to get head shot and without Duggan shipments gone, guards will wear bullet proof helmet. You want to have some kind of flying vehicle because targets are all over the map.
Power drills: You wanna get it if you think there is enough time to hit deposit boxes AFTER grabbing all the main stuff.
Security pass: ALWAYS GET LEVEL 2 SECURITY PASS! This saves you a ton of time from hacking key pads. You can cycle through this option to a picture with a valet and a dealer.
Acquire masks: A complete waste of time.
EMP device and infiltrate suits: The former cuts power out and the latter gives you nigh vision in dark as well as the ability to rappel down the elevator well when entering casino if you choose some doors near helipad as entrance. If you want to sneaky in or out more easily, go ahead and do both. I think it's not worth it. Gun is your best friend.

Planning Board
I usually chose staff lobby or waste disposal as entrance. But you must choose staff lobby as exit and select high level buyer. Staff lobby door is close to both sewer and nearby police station, and high level buyer gives you most pay. And DO NOT ever buy decoy or clean vehicle. They are total waste of money.
Finale
The general rule is DO NOT kill guards if they are not in your way, or patrolling to a dead body. Also watch out for cameras. You can only shoot down 1 camera. So just stun them. It can be difficult if teammates are not on mic cuz you might need to take down some guards in pairs. What I usually do is typing "Can someone please aim with me? You aim at right guy and I aim at left guy, then I fire right after you." in chat box. I found it works well as long as teammates read English. Probably many of you already knew this but you can hit daily vault twice both on your way in and out. The gate control is in security room. Another important note is that the guards will be able to see you though glass on doors, but they will not be able to see you through bullet proof glass around security room. As far as after getting into the vault, just make sure get your ass outta there before times counts down to 0. And also, elevator is for suicide only. TAKE THE STAIRS.
Then it's much easier. At this time you have not alerted anyone yet so turn to your right after getting out of casino. Check out the map below where I drew a route to a safe spot to jack a ride from NPC. You just need to make sure to knock out the first NOOSE on the left side of van, and knock out the second one patrolling the Lost club house. Don't shoot because that will alert them. After jacking a ride now you have 2 option. First is to go down the sewer where I marked with black circle, or steal a chopper on the helipad of nearby police station where I marked with red H. You can practice both in free mode in terms of where to go in the sewer and how to get to the helipad, but please bear in mind that sometimes the helicopter doesn't spawn. And ALWAYS turn left onto the highway from sewer exit because turning right will take you near to casino and that will get heat back on you.
Escape Route

Big Con

From easy to hard: Gruppe Sechs, Bug Star, LS Water & Power, Young Ancestor.
Prep Board

Gunner: Hire the cheapest guy because you can't fire a bullet in casino. That will attract attention no matter where you are. The only way to kill anyone inside is knocking him out.
Driver: Hire the cheapest guy, period.
Hacker: Hire Paige or Avi.
Entry disguise: Gruppe Sechs gives you a clean run without alerting anyone until you get back to stair well. But I personally find other disguise more exciting. You just need to watch some Youtube videos before try them out. Young Ancestor takes longest time and most challenging imo.
Exit disguise: JUST DO IT. Without it, you will be hunted right after getting out of casino. Go get NOOSE or firefighter outfits. Firefighter mission is easier because you can call Lester to clear wanted level.
Patrol routes: I would say this is not necessary if you are playing Gruppe Sechs, but highly recommended if you are using other entry disguise because you are dealing with more enemies.
Duggan shipments: Not necessary at all! Since no shots will be fired, their protective gear doesn't do any use against knocking out.
Power drills: Same as other approaches.
Security passes: LEVEL 2!
Masks: Nobody cares.

Planning Board
This is the same as silent and sneaky approach.
Finale
There is nothing complicated about big con especially Gruppe Sechs. Just check your map for guards that are hostile. Guards and cameras marked in red circles are hostile while white color indicates "friendly". After making up to the ground level, you will want to circle to the back area and knock 1 guy out. Then make your way to laundry room and change your outfit. After that you can walk outta there like a boss.
Once you are out of casino, it's the same deal as silent & sneaky.

Aggressive

Unarguably the only approach to play with randoms lmao. But you do get less time in vault and will lose take from getting shot at.
Prep Board

Gunner: This can be flexible depending on your shooting skill. The cheapest guy already have automatic weapon so that's good enough for me. Go for better gunners if you enjoy shootout.
Driver: Do I need to say that again?
Hacker: Yeah one of those two.
Patrol routes: Nobody cares because it will be loud.
Duggan shipments: Let me say this, if you don't do it, it will take a full clip of mags with headshot to take down 1 guard. GET IT DONE!
Power drills: There is less time in vault so I usually skip this unless it's a crew of 4.
Security passes: If you don't get a level 2 pass then you are out of your mind.
Acquire masks: Literally no one cares.
Reinforced armor: It works like heavy heist suits in OG heists. It gives you more health but makes you run slower. If you have Duggan shipments wiped out then this is totally unnecessary. If there are rookie in your team then you might wanna get it.
Boring machine: This is a super effective prep mission as it allows you to enter vault level through sewer directly. But you have to have this particular access point scouted first.

Planning Board
To get in and out faster, you would still want to choose staff lobby. But entering through main entrance is more dramatic and funny. And for the last time I have to say, DON'T WASTE MONEY ON DECOY OR CLEAN VEHICLE!.
Finale
There is really no need to explain anything here. But some people do take a different route after getting out of casino, which is around the inside of race track. You can still stick the the route I provided earlier but you might encounter 2 or 3 more cops on your way to jacking an NPC ride.
Ok guys, go watch some Youtube videos and read some other guides if you have not done this before. I really wish you have fun out there and not waste other players' time by reading my beginner friendly guide. Casino heist is definitely worth playing because R* created this based on all the lessons learned from previous guides. It will be likely to be the template of next generation of GTA Online, which is just 20 years away!

UPDATE 4th June 2020: Nevermind the heist is fun as fuck and you can make 1-1.7 million in an hour and a half. I just didnt know how to grind this. ITS WORTH IT, and a very good investment
Spent +10 fucking million dollars on the most expensive arcade location, with all the games and upgrades, including the casino mock up and the security panel for practicing. The result? Arcade makes you earn 3.5k dollars per day. PER DAY. A day in gta online lasts 48 minutes. Maintaining all of my businesses costs me 30k a day. The best part is that I cant even get that money, because the safe box is bugged and I cant open it, because it has no door and my character gets stuck if I try to open it.
About the heist itself:
Set up missions are very hard. And I mean VERY hard. I chose the stealth score option. Turns out that you have to do a lot of shit. Travel from A to B a lot of times carrying pieces of equipment. Kill Avon soldiers that will obliterate the fuck out of you everytime. And even better, the prep missions must be completed in a public lobby. Yes, they nerfed the MK2 and suicide thing, but they converted this heist into a paradise for griefers.
Still havent played the heist finale because it took 2 hours to do 4 set up missions and I still have a lot of them pending.
This DLC has disappointed me a lot. Its overpriced as fuck, the casino mock up costs $130k and the security pannel for practicing costs $430k (not to mention that most of the arcade machines cost +$300k). The new vehicles are overpriced as fuck. Missions are very hard and long, and impossiblenfor people without a group of friends willing to help them, since in some missions you have to get 2 or 3 pieces of equipment and you can carry only one per person.
Been investigating and Ive seen that highest payout is 2 million. People say that its very hard to get even close to that payout because of the crew cuts, the small amount of time you get inside the vault for picking up the money and the gunshots of the enemies that make you lose a lot of money everytime you get hit.
This is a HUGE disappointment. I thought it would be as good as the classic online heists. No. Its stupidly hard, intended to make you earn the least amount of money possible. Looks like Rockstar made it extremely hard on purpose. This is why people use money glitches and hacks. Because it is not fucking worth it to be 5 hours doing set up missions and a heist for that ridiculous payout. Just seen the case of a guy of this sub who did the entire heist with a friend. He did it with a friend (2 players) and they got $1.1M which turned into $900k after losing 200k in the gun fights. Take the crew cuts of that 900k. Both players got 300k. It is not worth it. It is not fair. This is not a decent update. I feel stupid for buying everything.

Hello fellow redditors, i have been playing this game non stop since Epic Games gifted it. so, i will talk in every point i saw in this game that let me or my friends wanted to stop playing, dont take this as a harrass, but mostly as things rockstar could have made to improve the game.

Lets start from the basic.

Load Times: we timed how much time it takes to load from starting main menu to online, it tooks an average of 4-6 minutes if u go Single Player then Online, 6-8 if you go directly to online. like, this game bugs a lot and you HAVE to restart it or do tricky things like joing from social club in order to fix it. and this takes me to the second point.
Bugs: this game seems like a indie company made a fan made rockstar game in Bugs quality, like, freezes in lobbys, cant join friends, cant join heist, disconnects, game makes you load GTA V Single player a lot of times, cant quit a bugged lobby, and mother of god, heist like casino has A LOT of bugs, freezes picking up gold, freezes in the start that makes you restart your game, glitches in the vault. This game is so broken that if u stop picking up loot and re do it, it bugs and refill the thing like WTF?, how is this a thing?, and do you want to know how they solved it?, if you have 160k+ in loot it doesnt let you re-grab a loot.
Hackers: its not a surprise, hackers are everywhere, droping money, exploding people, god mode, changin weather, spawning vehicles, spawning things, disconnecting people, crashing the game, and the worst thing?, sometimes you have to RESTART your game in order to fix wath the hacker put in the map. (pd: and there are a few DANGEROUS hacks, one that makes your game change weather constantly from day to night with brigthness incrased, someone with epilepsy can have an attack from this. like mother of god.)
Heists: look, i am not a pro player, i like to tryhard games mostly in pve content, but this game has like less than 1 week worth of heist and "interesting" missions to do, and it was released 6 YEARS AGO. 5 normal heists, 3 final worlds and casino. thats all, and the better part, why i will re do any of them if casino gives you 1kk and the others gives like a maximum of 250k.
Grinding Money: Hey, do you want money?, okay, if you play with friends you can farm a lot of casino, and casino, and casino again, if not, prepare to deliver cars. and every passive money income is a waste of time except for bunker fully upgraded and buying supplies ever and of course you need 3 people to do them.
Difficulty: as i said, this game is NOT challenging at all, heist are SUPER easy, mostly if u already have a good vest and hp from level, the only one i had to restart was the last one of final world because it takes so long that you dont expect to run out of vests.
Stealth: stealth works so bad in this game, like you can be in front of a guy with 0 cover and if u are not in the vision cone you are ok, you can kill someone behind him and nothing happens, you can shoot a window and nothing happens, but its so clunky that sometimes your character moves horrendus, security cams works awfull too, you can run past them and everything is ok... sometimes. idk why GTA V doesnt learn from games like payday 2, why i will want to do a stealth mission in an awfull made stealth. there is a reason why everyone hates stealth casino, and it is because, why do that?, why waste your time with some stupid things like this.
Minigames the game: Wanna hack?, do this mini game that has 3-4 maximum patrons with every same answer. like, is not hard, is no something you learn to do, is something you learn from memory, thats not skill, thats simply stupid.
Rockstar Social club: when i started playing i thought it was because of the big wave of new people like me who were playing, 1 month after this service works horrendus still, at the moment i am writing this it is down.
PVP: i dont like pvp in this type of games, they are not made to be balanced and not has skill at all, but one thing is not being balanced, other is being stupidly broken, MK2 in a nutshell, forces you to buy things to counter it.
Player Base: who would think the average player base of this game is gonna be 8-18 years old kids, its stupid how horrendus the player base is, i know is a "chaotic" game, but like, one thing is being chaotic for a reason, other is being dumb, people killing some lvl 10 and shit talking like, oh yeah, is not like he installed the game today and you are lvl 150 with fully upgradeds weapons, vests, mk2, hydra, spamming ghost. you are clearly better than that guy.
Races: who would think a player base of kids would want to have a good race?, none, so neither do i expect it, joined a race, people crashing other purposely at the first corner because "wow its so funny to crash, it does boom XD" and lag doesnt help this a lot, the few people who knowed how to play properly lagged a lot and crashed because of it.
Arena War: hey do you know that kiddos like to crash cars, lets do a mode for them, okey but lets do they pay 4-5 millon worth of upgrades and car cost first in order to play fairly with people expended the same amount of money, and lets do the most boring mini games ever like a capture the flag where everyone spams bikes because crashing one with the lag the game has is impossible.
A reason to grind: and this is my last statement in this game, why do i ever want to play this?, i want to grind money for what?, a mk2 to kill kids?, a house that i will NEVER use, a car that i neither will use because i have a mk2 and stromberg to counter my same mk2.

My TL;DR: if u want a heist-stealth game, go play payday 2, if you want a race game, you have a lot of games like dirt, if you want a pvp shooting game go play CSGO or if you want a more arcade expirience go play Fortnite or PUBG.
This game is not worth playing more than a few days, i played it because of problem with my network that doesnt let me play a lot of other games and this one was a waste of time, i cant belive rockstar does things so bad.

Hello everybody!

The new Casino Heist has been out for over 2 weeks now and there is probably already plenty of guides about it on YT, but I've wanted to make my own guide for a while now and finally think that I have enough experience to make one. I have played the Casino Heist about 30 times now (lost count at 10) and played all the 3 different approaches with a friend, so anything I say about the finale in this guide will be doable with just 2 guys, unless I specifically say so.
Keep in mind this is not a completely flawless guide, I will keep improving and editing it whenever I learn something new. I hope this guide can help you fly through the Preps and have no problems doing the Finale.

6: Approach specific prep

Silent approach
Big Con approach
Aggressive approach

7: Silent Finale
8: Big Con Finale
9: Aggressive Finale
10: Tips and tricks

1: The Basics

First of all, do the Preps in a solo public lobby. Theres no reason not to do them in a solo public lobby since others can only affect your experience in a bad way, unlike selling MC stock where you will get a bonus for every player in the lobby. (Guide for making solo public lobbies here)
Of course you can do the prep missions with a friend, that way you can avoid having to go to a certain place twice in some prep missions, but it's not neccesary. If you and a friend both do your prep missions simultaneously, you will be able to do 2 Finales in 2 hours if you are experienced in doing the missions. If you don't have any friends to do the preps with, don't worry, they're all doable completely alone and shouldn't be a problem to a decent player.
Now for Arcade locations. Of course I have to talk about Pixel Pete's in Paleto Bay. If you plan on doing the Casino Heist multiple times for a good income of large amounts of money, invest the cash from your first couple of runs from Paleto Bay into a proper arcade. I own the Videogeddon arcade in La mesa (~1,8 million), which is the cheapest in LS, but imo the 8-bit arcade (~2,6 million) is the best since its basically on the same road as the Casino and its garage is way more accesible than the La Mesa one since over there you have to drive around to the back to get into the Garage (Always enter your arcade through the garage entrance, it saves a lot of time compared to going through the front door, into the management office and through the secret tunnel) Either way they are both viable choices, but you should forget about the other ones in LS.
Vehicle choice. Obviously the Oppressor Mk II is your best friend for most of the prep missions, but there are plenty other viable alternatives. The Buzzard can be spawned in directly in front of you via CEO vehicles (if you own one it's free, otherwise it costs 25k per spawn) The issue with the Buzzard is its armor. After taking a couple shots, and trust me, you will, your Buzzard will start to smoke and will then stop working within ~5 minutes. The Akula is another very viable choice, especially when looking at the fact that you will have to lose the cops a lot (the memes are true). It also has fast firing homing rockets (don't use the rocket barrage, it's useless for grinding purposes) which will also help (it has infinite (?) rockets so running out of them won't be an issue, unlike the Oppressor, which only has 20) The Hydra is another hidden gem for the prep missions, if you can fly it well that is. Keep in mind that when using bulky vehicles like Helicopters or jets, the La Mesa arcade will be even worse since you have to land on the road and walk around the back of the arcade, whilst with the oppressor you can just fly straight into the back alley.
Hard finales. After doing a certain approach, that approach will be locked for the next heist. After doing another heist with a different approach, the approach first used will become available again with a red skull signalizing it will be on hard. Choose your 2 favourite approaches (information about the approaches below) and do them back to back, as playing the heist on hard will of course result in the loot being worth more. Don't worry about the heist being to difficult on hard, the only differences for the 2 sneaky approaches is the amount of fingerprints during hacks and for the loud approach the improved armor will be more than enough to make the heisdt a cakewalk.
I recommend purchasing the keypad at the prep board and training your fingerprint hacking skills on there. Trust me, you'll want to be fast when it comes to hacking the keypads. I get the hacks done in about 15 seconds and that is usually fast enough to get all the loot I want.

2: Vault contents

Alright, now for the interesting part, the vault contents. You probably know by now that Cash is the worst option. The best option in terms of money is Gold, while artwork takes significantly less time to loot. If you plan on doing the heist as a 2-man team, aim for artwork, if you are more than 2, go for gold. Forget about Cash.
So how do you influence what loot the vault contains? When doing the scoping out the vault mission, you will be able to see what the vault contains. If it's what you want, then good for you, you may leave the casino and move on to selecting the approach and crew. If however the vault contains cash or whatever loot you don't want, you can "change" the vault contents like this:

Leave the camera
Call Lester WHILST STILL IN THE CASINO
Cancel the Casino Heist
Leave the Casino and go back to your arcade
Pay another 25k to start the heist again

The vault content will already be revealed. If it however still contains the unwanted loot, leave your arcade, call Lester to cancel the heist again, re-enter your arcade, start the heist for 25k again. You will then have to do the vault content mission again and if it still isn't the wanted loot, you may repeat the tactic above.
Don't worry about the 25k that you'll pay each time you restart the heist, good compared to artwork is worth about 200k more so you will have plenty of chances before losing money.
The following describes a controversial glitch that may be used to gain more loot than you're meant to, if you don't want to do this glitch, then you don't have to, but some people will obviously want to do this.
For the glitch, you need the vault to contain Gold. I would usually write this in the finale section but this may influence your decision on what loot to pick so I see this as a more fitting place to write it.
When inside the vault, the gold will be stored on several carts across the vault.

Go up to one and press E to start collecting the gold.
Collect every bar but stop at the last one
Press right click to stop the looting whilst there is still loot on the cart
Wait 2-3 seconds infront of the cart
Press E to start looting again

Voila, the cart will be full with gold again and you may now collect all the bars. This can only be done once for each cart, so after "filling up the cart" once you can collect all the loot off of it without losing anything. This way you can get up to ~3,7 million worth of gold. You will be able to collect more but the rest won't be added to your total, so you might aswell stop at that amount and leave the vault.

3: Different Approaches

1: Silent and sneaky
This approach involves you sneakily going into the casino with silenced weapons, sneaking your way to the vault and then getting out undetected again. I recommend playing this with people that are willing to communicate. I'm not saying you shouldn't pick this if you have to play with randoms, just make sure they are capable of cooperating before you start the heist.
The pros of this approach are that you will have ~3:25 minutes inside the vault and that you wont get shot (hopefully) so you wont lose any loot. This approach also lets you casually empty out the secondary vault opened via the security center (more about that in the finale section)
The obvious cons are that you need to have teammates capable of cooperating so they wont rush in, alert the guards and make you lose your sanity. The detection system is also very inconsistent and things that you might think wont alert the guards will turn out to do so, sometimes.
For this approach I recommend getting the artwork loot if you are just 2 players and gold (w/o glitch) if you are more than 2
The prep missions that may be skipped for this approach are:

Power drills, since the lockboxes inside the vault don't pay that much and it takes time to drill them open that can be used to loot the main contents

2: Big Con
You enter the casino in disguise and get out in disguise, making you lose no loot from being shot like in the silent approach.
First of all, USE THE GRUPPE SECHS UNIFORMS. For the gruppe sechs uniforms to becaome available, you have to photograph the security tunnel of the casino (see image below) By using the gruppe sechs outfit, you can walk straight into the vault without needing to kill anyone.

Service tunnel location
This is in my opinion the best approach since you can easily stay undetected the whole time and it leaves very little chance of failure by stupidity and gives you the full 3:25 minutes inside the vault for looting.
Recommended loot is once again Artwork for 2 people, Gold for 3-4 people.
The prep missions that may be skipped are:

Patrol Routes. You will only have to kill a maximum of 2 guards and they will be near enough to pop up on your radar anyway
Duggan shipments. You will kill the 2 security guards with melee since your weapons don't have stabilizers and their armor doesn't save them from melee attacks.
Power drills, again, since the effort of drilling the lockboxes is not worth it most of the time

3: Aggressive
The most barebones approach involves you shooting your way through the casino and blowing the vault open. This is the easiest approach to do with randoms and can even be done with level 10s who just got their first million.
I recommend photographing the sewer entrance to shorten the way that you have to fight your way through (see image below)

Sewer location
The recommended loot is always artwork since you won't have as mcuh time in the vualt, so the faster you get all the loot the better.
The prep missions that may be skipped for this approach are:

Power drills, obviously since you have less time inside the vault.

4: Crew

Crew choice, seems like a hard decision, really isn't. You basically want to pick the cheapest crewmembers who give you the best hardware.
1: Gunman
Karl Abolaji. For every approach. This might seems like a stupid decision seeing as he only gives you a sawed-off shotgun or heavy revolver for the loud approach, but you will actually get an SMG aswell, which is very usuable for the loud approach. If you don't feel comfortable with just an SMG, Pick either Patrick McReary or Gustavo Mota. Packie will of course be very hard to unlock (Guide to unlocking Packie here) but he will give you a combat MG for only 8% of the cut, whilst Gustavo Mota will give you a Carbine OR Assault shotgun (with the SMG) for 9%
For Silent and Big Con, Karl will give you Micro-MPs, which are more than capable of doing their job, that being killing guards in the silent approach. For Big Con, you could actually play completely without weapons since you only need to melee 2 guards.
2: Driver
Probably the least important crewmember. Some people don't even use the getaway cars provided. So of course, pick Karim Denz. He will be able to source oyu the Sentinel Classic, which is a more than capable Car for getting to the needed places (more information about getaway in the finale section) for the smallest cut.
Of course you may choose other drivers if you want to unlock the trade price for any of the vehicles.
3: Hacker
The most important crewman. Really the only viable choice is Avi Schwartzman, who can be unlocked by destroying the 50 signal jammers spread around San Andreas (Guide for 50 jammers here) He will give you the most time in the vault (Paige is an "expert" hacker aswell but she will give you ~15 seconds less inside the vault) Don't even think about all the other hackers, the hacker is no place to cheap out.

Ideal crew layout

5: General Prep Work

Alright, in this section I'll go over all the prep missions and give some tips and hints on what to do and what not to do and what vehicles work best. First of all, don't buy any of these preps for 70k, they're all somewhat easy to do and shouldn't be a problem for a solo player.
1: Untraceable weapons
This mission is be annoying but also easy. There are lumtiple types of this mission, and whilst none of them are a true challenge, they can be annoying to do since you have to either fly/drive a slow vehicle or collect 2 crates.

Noose Vans: There will be 4 Noose vans around the map and you have to blow the back door off to check for the weapons. You cannot lock onto the vans with homing missiles, so you either have to have good aim or use stickybombs in a ground vehicle. After finding the right one, you have to take it back to your arcade, after losing a wanted level. The annoying thing is, you cannot call Lester to lose that wanted level and the Van is very slow, I recommend driving through a tunnel where the cops cannot go to lose them.
I/E crew: You have to fly to the shore and find A couple of guys exporting the weapons, just blow them up or murder them any way, get in the Tula and fly to Sandy Shores airfield. When taking off in the Tula, switch to VTOL mode and gain some forward speed and altitude before switching to normal flying.
Lost MC/Vagos: You have to go to the clubhouse of the Vagos or Lost, clear the hostiles, find the weapons inside the clubhouse and bring them to your arcade. You will probably die the first couple times you try this mission, but you'll get the hang of it eventually. If you get the Lost MC mission and you have an arcade in LS, I recommend just finding a new session if you're alone since flying to Paleto Bay twice can be very time consuming.

A weapons case inside the Lost MC clubhouse
2: Getaway cars
This mission is somewhat easy for all types, but of course it's much faster done with a friend since you will have to get 2 cars most of the time.

Police warehouse: You have to go to a vehicle warehouse of the police and get the 2 cars out of there, don't worry about the sounds of the engines when in the warehouse, the cops inside seem to be deaf. When driving outside, be careful not to alert the cops standing outside or you'll have to lose your wanted level first.
Valet: You go to a hotel, scare away some valets, dress up as one and wait for the cars to arrive. Nothing much can go wrong here. The only things you shouldn't do is shoot or knock out the valets and bump into somebody infront of the hotel. Just simply bring the cars to your arcade and you're done.
I/E crew: You have to take the cars off a crew who just imported them. Just go to the location, kill the goons and take the cars. Watch out however, the enemies have extremely good aim and even a single enemy can kill you in a couple of seconds. Just use your homing rockets (don't worry, the getaway cars can't be blown up) to kill them, get the cars and bring them to your arcade.

3: Hacking Device
Seems like a simple mission, and it is. There are only two types of this mission, and they are both somewhat easy.

FIB: Collect a security pass off an FIB agent by brutally slaughtering him and his fellows, go to the FIB office, find the briefcase with the hacking devise, get out, lose the cops and bring it to your arcade. When killing the FIB agent, an exploded vehicle may block the agent's corpse. Just get another car to push anything away. There is also a bug where the corpse will either always be considered as blocked or ont even appear, if that happens you have to find a new session and restart the mission.
Noose: The early part is pretty similar to the FIB type, you collect a keycard off of an agent, enter the Noose building and use your phone to find the hacking device. When you get out of the Noose building, the alarm will always automatically go off, just fly away with your OppressoAkula etc. and lose the cops before bringing the hack device to your arcade. You can also assassinate the agent silently when collecting the keycard by approaching him, waiting for him to go away from the other 2 agents and then bopping him in the head with a gun, but form my experience its faster to just blow him up since you'll most likely lose the cops on the way to the Noose building anyway.

The briefcase you're looking for
4: Vault Keycards
This one has 2 mission types. In one you just go to two guards who have the keycards, eliminate them silently by smacking them in the head with a weapon and then looting their keycards.
The other mission is a bit more complicated. It involves you getting a prison bus and entering the bolingbroke prison in that disguise tho then silently murder a guard there who has the keycards. You actually don't have to collect or even blow up the bus, you can fly straight to the prison, kill the guard and get the keycard. Keep in mind thatr you wil get 4 stars doing it this way and there are snipers on the 2 adjacent towers to where the keycard guard is, so you'll wnat to kill those first before looting the guard.
The recommended vehicle is the Oppressor Mk II just to get around faster, but the Akula is a very viable choice aswell to lose the cops more easily after flying to the prison.
5: Guard Patrols
Pretty straight-forward mission. You go to a Duggan security meeting, kill all the guards, find the correct car, photograph the plan and then get out.
This mission can be done stealthy, but it's basically impossible, you're better off juzst shooting them straight away.
The correct car will always be a Felon GT and there will always be 3 of them in the same positions, so you get the hang of where to go after doing it a couple of times.
Once again the Oppressor and Akula are your go-to vehicles for this mission, but DO NOT use the rockets to blow up the guards, the chance of accidentaly blowing up the car with the plans is not worth the risk, and I suggest you also dont use a Minigun since that can also bvlow up the car pretty quick.
6: Duggan Shipments
This is the most stressful prep. You need to destroy 10 of Duggans shipments in 10 minutes to weaken the guards inside the casino. The easiest way to do them is with any chopper with rockets (Akula, Hunter, Savage etc.) or the Oppressor Mk II (you may need to fly an optimal route so you have enough time to destroy all of them.
It is actually no neccesary to destroy all of them, for the silent approach destroying 2-4 is sufficient to make the guards not have helmets (you don't want to bodyshot them anyway, that might make them sound the alarm) but for the loud approach, it's best to destroy all 10 of them so that the guards only have Pistols and Micro SMGs.
If you fail to destroy all 10 in time, you can quickly leave the session before the time runs out and retry the mission.
7: Security Intel
This prep is unlocked after completing the 6 Casino missions unlocked by buying a Casino Penthouse. It can only be done once, so you won't have to replay it every heist.
The mission is simple, you go to a mall, meet Vincent, get the stolen car back for him (use a vehicle with drive-by weapons, helicopters and the Oppressor aren't good for this mission) and done, you can now see all the cameras inside the casino.
8: Power Drills
This mission also has 2 types, but the van one is much rarer. The common one involves going to a construction site and getting 2 power drills.
When you get to the cunstruction site, there will be a white icon on the map. Go there and equip the helmet (your character may remove the helmet shortly after equipping it but the disguise will still work) then just go and check the boxes for the power drills
YOU CAN CARRY BOTH DRILLS AT ONCE! That way you don't have to fly all the way to your arcade and back to collect the other drill.
The second type involves stealing a van with the drills inside and taking ti to your arcade. Simply use a vehicle with drive-by weapons (Once again no chopper or Oppressor), kill the driver AND passenger (he will get on the driver seat after the driver dies), collect the van and take it to your arcade.
9: Security Pass
First of all, ALWAYS get the level 2 security pass (the one showing a valet and croupier on the mission picture) The level 1 pass will only get you through the outside doors whilst the level 2 pass will open all doors except the level 3 ones inside the vault.
Once again, two types of this mission may occur. The first involves you stealing a hearse from a church parking lot. You will then have to lose a 2-star wanted level and drive to a hospital where you then have to find the corpse of a valet and get his security pass. When entering the hospital, your character may automatically have a weapon drawn, so pay attention to that before running through to the corpse.
The other type has you going to the party of a croupier, waiting until lester found the right guy and then take the security pass off him. When you get to the party, there will be a pavillon with people dancing, just go there and start dancing until lester has found the right guy. When you then search the croupier for the pass and it's not on him, just search for a small purple keycard (it can be somewhat hard to find but it will always be in the same locations) and collect it.
As for vehicles, anything goes. The Oppressor will probably get you where you want to go the fastest.

The pavillon that you can dance under

6: Approach Specific Preps

Silent approach:
1: Drones
You have to destroy 5 drones spread around LS and collect their parts. Pretty simple mission, use something with rockets (Oppressor will have better rockets than Helicopters) and blow up the drones. You can of course carry all 5 drone parts at once.
It can be tricky to lock on to the drones as you will also lock onto the cops if you have a wanted level, just swap from non-homing to homing rockets if you locked onto the wrong target.
2: Laser drills
This can be a difficult mission. You will either have to take the two drills off the military, which may be hard since they are very accurate and theres a lot of them, but you can use you Oppressor or Akula rockets without worrying about blowing up the drills, just be sure to stay far enough away, their aim is surprisingly good. Be careful when collecting the first laser drill, if the cops kill you your Oppressor may be impounded and you have to use a different one.
The second type will be to take the drills from a bunch of Cliffford soldiers (apparently they're still around) which is way harder than the military since the cliffford soldiers are EXTREMELY accurate and there will even be a juggernaut and snipers. I don't recommend using the Oppressor for this as you are very vulnerable when standing still, go with an Akula instead. Just kill all the soldiers, enter the warehouse, kill some more soldiers, take the drills and get to oyur arcade.
3: EMP
Another pretty easy and simple mission, you will have to collect a cargobob (with an extra long cable) from the airport, fly to the LS University and steal their EMP. Then just fly to the drop-off, lose a 3-star wanted level by evading the helicopters and drop off the EMP.
Some people skip this mission and the next one, but I use the EMP during the finale to casually do the last hard part so theres no risk of screwing anything up. If you are however coordinated enough to not need the EMP, then you may skip this and the next prep
4: Stealth Uniforms
I highly recommend paying for this mission, it can be very annoying and you get the 70k back from the finale anyway.
This mission involves you going to humane labs and assasinating guards silently (very similar to the infamous deliver EMP mission) and getting the uniforms from the garage where you would park the insurgent in the Humane Labs Heist. This mission can be done quickly if you have a buddy, if you don't, it's better to just skip it and pay the 70k (If you don't plan on using the EMP you don't need to do this mission anyway, it's only for the night-vision equipment)
Big Con approach:
For this one, I'll only talk about the group sechs uniforms, since this is the easiest method of doing the Casino Heist by far. If you want to use a different uniform to unlock it, go ahead, but do be warned that it will be significantly harder to fully stealth.
1: Group Sechs, part 1:
Simple mission, go to a mechanics repair shop, kill the mechanic after realizing the Stockade is locked, get the keys and drive away. You will get a wanted level, but you can call Lester to easily lose them.
2: Group Sechs, part 2:
A bit harder, but still pretty easy. This mission is similar to the Patrol routes mission, you have to go to a group sechs meeting, kill everyone (this can also be done stealthy, but its again almost impossible), photograph the license plate of the black stockade, send it to Lester and then get the equipment and bring it to your arcade. Again as with the Patrol routes mission, do not use explosives to kill the guards as you might accidentaly blow up the equipment. You can call Lester to get rid off your wanted level.
3: Vault drills
Yet another simple mission with two types

Fleeca: A crew of bankrobbers will be robbing a Fleeca-bank with the needed drills. Go there, kill em, get their drill, lose the cops, bring the drills to your arcade. Pretty simple, but you cant call Lester, so using an Oppressor or Akula is beneficial.
Heist crew: A bunch of heisting dudes are being arrested by the police. Go there, kill em, get their drills, lose the cops, bring the drills to oyur arcade. Pretty simple, but you can't call Lester, so using an Oppressor or Akula is beneficial....hm, I'm having quite the Déjà vu.

4: Escape Outfits (Noose)
I'm choosing Noose outfits because they look better (and I'm sure they are in some way better than the Firefighter uniforms, I just don't know how, you seem to get spotted in the Noose uniforms aswell)
Simple (yet somewhat difficult) mission. Go to the mission row police station, kill all the cops there, find the Noose equipment, loose the cops and bring them back to your arcade. You can't call Lester to lose the cops so an Akula would be helpful. When collecting the second uniforms doing it solo, you will once again get 4 stars, so be ready to evade the cops again. Also, when you die at the police station, the cops will most likely impound your vehicle, so a careful approach would be better.
Aggressive approach
1: Thermal explosives
Loud has some pretty annoying mission, this being the first one. Once again, there are 2 types of this mission

You have to go to some rednecks and get the explsovies off of them. Just kill them all (once again no need to worry about blowing anything importnat up) and collect the boxes. They have a pretty big pickup distance so collecting them in a Helicopter should be no problem
SecuroServ Warehouse: Go to a warehouse, kill some people outside, kill some people inside, find the explosives, bring them to your arcade, no cops, pretty easy.

2: Vault explosives
This may be the most annoying mission of the entire heist. You have to go to a crash site of a plane, dive to the wreck and collect the explsovies. If you own one, put on a diving suit BEFORE starting the mision, you can't access the outfits during the mission.
When arriving at the crash site, you can dive straight to the plane if you have a scuba suit equipped, that saves you the killing and you won't get shot at instantly. Otherwise you have to kill some goons and equip a scuba suit nearby marked on your radar. When you collect the explosives, 3 helicopters will spawn. When you get out of the water, kill the gunners inside the helicopters, not the pilots. The helicopters would respawn and by only killing the gunners they will just follow you without shooting you.
3: Improved armor
You'll probably want to buy this prep, since this mission can also be very annoying. Two types of this mission, both are very unpleasant.

Humane Labs: Go to the beach at humane labs, get into a scuba suit, dive through the cooling tunnel into the facility, find the armor and bring it to your arcade. This mission may not be that hard, but the long swim and indoor fighting stretch out the mission and it quickly becomes repetetive and boring. There will atleast be a buzzard when you get out of the facility.
Merryweather bunker: Enter a bunker, kill the merryweather goons, find the armor and bring it to the arcade. Simple mission on paper, but the enemies will probably kill you atleast once and the armor sometimes can be tricky to find, I once spent 15 minutes searching the armor.

4: Drill
Simple mission and only needed if you plan on entering the casino through the sewers. Just go collect a truck with the drill loaded onto it, drive it through the water channel and into the sewers.The time you save by going into the casino through the sewers is probably negated by the time it takes for this mission, but having a more relaxed finale is certainly worth doing one more short prep mission.

7: Silent Finale

Alright, it's finally time for the big moneys, the finale. For this approach, you'll want to go in through either the garbage disposal or personnel room and go out through the personnel room. ALWAYS choose the high end buyer, he will give you the most money.
The finale starts very simple, you drive to the casino and enter through the door you chose. Careful, there will be a camera that you need to zap using your stun gun. When inside, there will be metal detectors that you need to disable by shooting the current box with the stun gun. Sometimes there will be guards watching the metal detectors, in that case you need to take them out before you go through.
When taking out guards, it's better for player guy to kill 2 guards facing eachother, as internet issues may cause in the alarm being raised even if the guards are killed simultaneously. You have more than enough time between shooting the first guard and the second guard raising the alarm that it shouldn't be a problem, just make sure your teammates stay back and don't interfere with the player killing the guards.
After clearing the first area (see picture below), you enter the security room through one of four doors (most of the time 2 of them are locked, can be seen by a red display on the keypad instead of the blue diamond) and then wait for the guard in the hallway to move out of the cameras sightline (Do not worry about the glass at the security room, for some reason guards can't see through it. The y can however see through the glass of the doors) Then you follow him (watch out for the camera) and shoot him in the head. Feel free to then clear the secondary vault by one play opening it for another player to loot (theres another button to open the vault inside, the player pressing the button only has to let him in) and then USE THE STAIRS to get to the vault floor.
When going down the stairs, a guard will walk up the stairs, shoot him in the head, disable the camera in the stairway and make your way all the way down.

Getting to the stairs undetected
On the vault floor, go out of the stairway and take out the 2 guards to the left. Then set off your EMP (this will also obviously disable the cameras) by having the host open their phone and using the securoserv-hack. The lights will then go out and you can rush into the main lobby and take out the 4 guards there. You can ignore the last guard inside the security room, just go to the keypads, swipe both at once and enter the mantrap.

Getting to the mantrap undetected
When at the vault door, 2 guys get out their laser drills and start drilling. The drilling is very simple, you just keep the drill as hot as possible whilst not overheating it. When inside the vault, take as much loot as you can but make sure to leave the vault before the time runs out (I recommend stopping the looting with 20-25 seconds remaining to ensure you have enough time to get out).
When getting back into the vault lobby, there will be 2 guards walking past the stairway, you can ignore those, just use the stairs to go up again (and don't forget to disable the camera in the stairway)
When back in the main floor, follow the route shown in the picture below whilst taking out any guards in the way (2 will be in the security room, you can ignore those) and leave the casino through the personnel door. Don't worry about the metal detectors whilst going out, they dont seem to alert the guards.

Getting out of the Casino undetected
When outside, again follow the route shown on the picture below to get to the getaway cars (locations may vary with different drivers) and drive into the sewers. Then spend some time in the sewers by either waiting or driving to another exit (I personally like to drive to the exit right at the highway so that the drive to the buyer is as fast as possible) Make sure not to drive too close to the Casino, as that will get you 5 wanted stars. I recommend avoiding the freeway next to the casino, you may however use the road to the north-west of the freeway.

Escape route with getaway car locations in pink (when choosing the 5% driver)
Then just casually drive to the buyer after you've lost the cops and there you go, fat loot.

8: Big Con Finale

This is the easiest finale by far. Choose the group Sechs entry uniform, noose escape uniform, the personnel rooms as the exit and of course the high end buyer.
Take the Group Sechs truck to the Casino and through the service tunnel, wait until the guard lets you through, park it on the yellow marker and use the elevator or stairs to get to the vault floor.
On the vault floor, just run to the keypads for the mantrap. The guards don't care if you're running or even jumping, just don't bump into anybody and don't draw your weapons.
The just casually loot the vault and again, make sure to get out before the time runs out (stop looting with about 25 seconds left to have enough time to get out safely.
Then just walk through the mantrap and the vault lobby again but USE THE STAIRS to get to the main floor (the camera will not raise the alarm, don't worry about it). Make sure you are all past the camera before going to the main floor, as anyone who didn't go past the camera will get detected due to the guards being alerted and a wanted level appearing. When at the main floor, use the route in the picture below to get to the Noose outfits and switch into them to walk past the last few guards without any problem.

Getting out of the Casino with the Noose uniforms
When outside, follow the same route as in the silent approach to get to the getaway cars. Drive into the sewers, lose the cops in there and then again casually drive to the buyer whilst avoiding driving to close to the casino.

Getting to the getaway cars and into the sewers undetected

9: Aggresive Finale

There really isn't any major explanation needed for this approach, as you won't have to worry about getting detected.
If you chose to enter through the sewers, drive there, enter the tunnel that was dug with the giant drill and plant explosives at the wall to gain entrance to the vault floor directly.
Then just shoot your way to the mantrap keypads and have the others protect the people opening the mantrap if you are playing with 3 or 4 players.
When looting the vault, you won't have to worry about getting out in time, and the nerve agent does very little damage, so don't be scared to take longer than the timer says.
Whilst shooting your way out of the casino, you may use either the elevator or the stairs to get to the main floor. Going through the security room allows you to evade any guards that may be in the south corridor.
When you get out of the casino, you may follow the same route as in the undetected approaches or run directly to the getaway vehicles, although you will probably get shot more doing that and therefor loose more money.
Get to your cars, drive into the sewers and lose the cops. Then you're just one casual drive away from making another bunch of cash. I highly recommend getting bulletproof tires for your getaway cars on this approach, and whilst you are spending that 10k per car, why not go big and get the 15k upgrade that laos makes the cars go much faster.

10: Tips and tricks

So in this section (which I will probably expand with additional tips, feel free to leave some in the comments) I'll go over some of the things I didn't mention that may save some effort or time when doing this heist.

You can lose the cops by going into the back of your Terrorbyte if you aren't carrying any equipment (useful during the untraceable weapon mission with the Noose van)

That about covers it for this heist. This has unexpectedly been quite the project for me, it took me 3 days of writing here and there and getting screenshots, so leaving a smol updoot would be appreciated. If you have any questions, of course feel free to leave a comment, I'll try my best to read every single one of them :)
Happy heisting! (and may your sessions be free of griefers!)

Just sharing some of the things I learned from doing the casino heists a bazillion times. These are not "easier ways of doing things", just some things some of you might not know (kudos if you do)

There are easier variants of most heist preps (if you are solo), like the FIB for hacking device, vagos HQ/ plane for weapons, etc. If you launch a prep and get the tougher one, if you have living quarters in arcade, use it as your spawn point, and just look for a new session from the online menu. You'll spawn in the arcade and you can launch the prep again with a chance for the easier prep. It might get boring if you are doing this regularly but you save a lot of time with the easier preps solo.
You don't need the Tunnel Boring machine prep for the sewer entrance in Aggressive. It seems like the logical thing you'd need , and if you choose sewer entrance without doing the prep, you'll see the boring truck parked outside and the sewer is now a tunnel, implying it was used, even if you didn't do the prep. My theory is it's there by some weird design bug, but hey, less work for you so might as well enjoy it.
You can open the context menu and go to styles > accessories and change something like your glasses (glasses on/off, not switching one glass with another) when you are not in direct view of the cops (the stars are blinking) - you can drop one star of wanted level. If you do this quick for a three star level like the patrol routes, and drop to two, the chopper has a chance of not spawning
You can call Lester to remove the wanted level during the entire gruppe sechs prep for Big Con (both the car and the outfits)
In Silent and Sneaky and Big Con, a good, fast car usually spawns in front of the sewer tunnel (at least it does always for me). If you have Artwork, and didnt get a good civilian vehicle on your way out, you can just run to the sewers and grab it. For me it's faster than getting the getaway vehicles across the street, and stay under the cops' eyes because we are running right out to the sewers (going left right after vaulting the fence takes you to the sewer area while the cops are looking at the roads)
You need to do 0 duggans for Big Con. That one or two people you need to knock out will go down just the same with 0 duggan shipments destroyed. In silent and sneaky, just 3 would do because that removes the helmets and that's all you need because you'll be making headshots.
Doing the Patrol routes has an effect on Aggressive. Enemies are not usually marked untill they are closer to you or shooting at you. With Patrol routes done, they will be marked right when they spawn, which is helpful specially with the lowest cut gunman. With Packie, this is VERY fun.
If you cancel the Casino Heist while in the casino (or before you get the "prep complete" message), when you walk away, you will still get the prep complete message, and when you start the heist again, you won't have to do the scope mission and will have a chance of getting another target based on RNG.
You can do a free Fingerprint practice here: https://mikecoon.github.io/gta-online-finger-hack-maste
On the missions where you need to pick up two things and they give you a wanted level (weapons or getaway vehicles) - you can take one of them out of the area (just outside) and then kill yourself to drop the item, run back and get the second item (the entry dot won't be there but if you walk to where it was it will take you inside). This way you need to lose the cops only once because the next time you go back to pick up the dropped item, it is outside the area which gives you a wanted level.

Merry Christmas everyone :) I decided to write a little summary to useful things.

I'm going to be honest, I've had it up to here playing the Diamond Casino Heist and that is due to one thing, randomers! Now before you accuse me of being a whinging kid, hear me out! The only styles of play I use are Silent & Sneaky and The Big Con because those are the only two modes where you can walk away with all the money and without a scratch, if done right. But, many a times I have to rely on randomers because my friends don't play GTA Online as much as they used to. Now, The Big Con is by far the easiest way to play and you can even successfully complete the heist with no cooperation/coordination whatsoever.
The absolute bane of my existence is Silent & Sneaky with randomers! I have left soooo many heists because of randomers and in that time I could've completed two other heists! Why do you shoot the two cameras outside of the staff lobby instead of stunning one and walking right past it?! Why is it that when I've shot the camera by the elevatostairs to stop it seeing the guard's body, you go ahead and shoot the camera on the stairs on the way down to the basement when Lester has clearly warned you not to shoot another?! Some of these mistakes have been made by high level players. Finally, when we're in the vault and collecting the loot, why do you go off and drill the safes instead of leaving that till after all the loot has been collected?! All I'm saying is that if you have to make these mistakes for whatever reason, why not make them after we've collected the loot so that we don't have less time in the freaking vault, bearing in mind we're playing on hard mode so there's two hacks to complete instead of one.
I've learnt my lesson, I'm only playing The Big Con and Aggressive with randomers; I'd rather wait a year for my friend to come back if it means I play Silent & Sneaky. However, I chose to write this in the hopes that whichever randomer is guilty of these mistakes, reads this and stops doing that because I feel bad for the next person who is in the position I was in.
TL;DR? Randomers who play Silent & Sneaky Casino Heist, stop shooting the two cameras outside the staff lobby before we've even gone inside. Don't shoot another camera when Lester has warned you not to and DO NOT start drilling the locks before all the loot inside the vault has been collected. If in doubt, watch these videos before you ruin someone else's heist, thanks :). https://www.youtube.com/watch?v=6_9InXoEl1M&t & https://www.youtube.com/watch?v=oSkiN_sdg1Q

I loaded in today with my friend to do the heist.

Plenty of thing that were cool, lots of path, lots of different interaction, pretty much like payday so i though "heh maybe this time it will be a worth it heist".
And so it begins, my friend buyed the arcade thing and we got to do the heist. and what a nightmarish hell of a 8 hours it was.First of all, every god damn set up mission was in freemode, so not only are they not paying, they are fucking lame. that was probably the most boring 4 hours i've done in GTA online. but guess what ? it's paradise in comparison to the boring, buggy, unpleasent, randomized and unrewarding heist that was to come.
Just to be clear, we did EVERY mission that was needed, and every optionnal ones as well, my friend even paid something like 600K to get the casino model and the hack training thing and we got every spotting that was possible, we still don't know what the casino model is for, we got the 2nd gunman and 2nd driver and basic hacker (maybe the worst mistake we've ever made on this game.)
And we choose the Stealth option, why ? because we though "everytime there is a stealth heist or anything, it always go loud at some point, and if we choose a dedicated stealth path, it wont go loud if we get everything done am i right guys ? RIGHT ?"
so we choose a path and the first bad thing happens (i mean except for the boring ass preps missions but you know what i mean) it only pays 1.6 Million... a possibly 5 hours (yes i know with time we will do it faster but not me i'm not redoing this shit.) heist only pays 800K per person if done in a 2 man team. Ridiculous.
The bogdan problem pays 1.2 million and only require 2 hours of your time. you only get +400K for doing something as long as 2 and a half bodgan.
and so it begins, we land on rooftop, everything fun and all, we got to the 1rst room and oh boy, to be honest, the heist was kinda cool until the vault. but there is 2 reason this heist is a nightmare. the 1rst being that if a guard spot you when you shoot him, there like a 60% chance that he will shoot when dying and alert everyone. And the 2nd reason is that they some what decided to implement the sound detection, and it go trough walls...
what does it means you may ask ? well it means that if there is a CCTV in stairs and i want to stun it, and if a guard on the same floor of the CCTV, floor that i am not on because i'm in the upstairs so i can't know if the guard is here throught the map, when you stun it, the guard will automatically alert everyone.
And the thing is, between the 1rst floor and the vault there is only 2 ways to to go, the first being the elevator, that make you spawn in front of 2 guard so when you shot them there is a high chance that they will shoot, and the 2nd one being the staircase, that as a CCTV that is on the same floor as the vault, so 1 in 3 time, a guard will be alerted when we stunned the CCTV.
we stayed on the first room for something like 2 hours, between the guard that hear your shoots, the one that shoot when they die and this fucking gambling between the staircase and the elevator.
but we somewhat get in the vault room. somewhat somehow. we get to the vault room and we kill everyone here, so we are in the vault, hooray! we open the vault aaaaaand... gas...
Gas...
Gas in a stealthy mission...
...
Why ?
Why is there gas ?
Why is there gas when we killed everyone in the 1rst and 2nd room ?
Why is there gas when we did EVERY optionnal mission there is ?
Why is there gas when apparently nothing got thrown off ?

we don't know, but there was the gas, we got a minute and a half to collect 6 money point with 4 locked behind 2 hacks, in a minute and a half window... we only got 4 of them, so we only got a million dollar...
a million dollar heist for 3 hours of prep. Outrageous. but because the game is unfunny, the alarm goes off for no reason. we now need to fight off swats, with only a pistol, a tazer and a shotgun. with no armor whatsoever. and because the game is EVEN MORE unfunny, if you get shot you loose money.
So here we are fighting for our life, trying to get to the cars, loosing money like a leaky pipeline.We lost like 4 time, because obviously we don't have the stuff too deal with it.
we got to the cars thinking it was done finally, just need to go to the meeting point, well you'll first need to loose the cops because the devs aren't payd enough to develope a cool way to loose them, and last but not least, the tires of the cars aren't bulletproof... We paid EXTRA CASH to get a better driver that wasn't there, to get us cars, and he can't even make the tire bulletproof, wtf.
why did i need to pay this guy ? i have a full market about stolen cars, why did this guy needed to be hired when he can't even pick bulletproof tires. fuck off.
so we lost because my tires got shot obviously so we made the right choice. Waiting in the sewer for the stars to dissapear. Wow super cool and super refreshing experience.

we finally got to finish the heist, we got 366K, we loosed so much time i don't think i want to play the game anymore.

Who thought it would be rewarding to pay this less ?
who thought sound detection that go trough walls was a good idea ?
who thought making you hire people without knowing what they do was a good idea ?
who thought PUTTING GAS AND GOING LOUD on a FLAWLESS STEALTH HEIST was rewarding and refreshing ?
So yeah, as a big PayDay 2 player, i wanted to congrats rockstar, for making what i consider the most nightmarish, unrewarding, unsatisfying, unfunny heist i've ever did. And that's coming from someone that did old One Down goat simulator and bomb forest in payday 2.
I didn't thought rockstar could do worst than the doomsday ones, well they overkilled it.

TL;DR: thinking about stealth in GTA is a complete joke and doesn't it exist. New heist sucks. Friend lost money.

So something strange happened last night doing the diamond casino heist finale with a couple friends of mine. Not sure where else to post this, but I thought someone with more glitch experience might want to screw around with this.
So we were doing the silent and sneaky approach on normal, gold in the vault, 3 members in the group.
I have a lot more money than one of my friends so I was trying to be generous and take a 15% cut giving friend 2 his normal 30% and friend 3 a 55% cut. We were already planning to use the gold duplication glitch so the goal was to get friend 3 enough extra money for his arcade.
From the heist board we were in the order of 15%, 30% and 55% in descending order. For reasons I cant remember we ended up having the mission start by the timer running out instead of everyone readying up at the heist board.
Right after we left that screen and moved onto the one where we picked our outfits friend 2 (30٪) says that on his screen he saw the payout split was 70, 15, 15.
So we brush him off because the 2 of us clearly saw the 15, 30, 55 split and we go on with the heist. After a bunch of nonsense we pull off the gold duplication glitch and walk out with a 3.2m take because I'm still the only one who can pull off a timely thumb print hack.
Mission ends and I'm the only one who doesnt get kicked from gta online, which usually 1 or 2 of us does. I dont pay attention at the arcade party after screen but I realize I made 1.7m which adds up. 3.2m - 24% is roughly 2.5m and 70% of that is 1.75m. I start apologizing for the mistake friend 2 logs back in and says he made about 500k which is weird because it's around a 20% cut. Friend 3 calls it a night without logging back in. Friend 3 informs me today that he logged on and had 1.7m in cash from the heist.
I have no idea if these results would be repeatable but something happened that worked out very well to our overall gain and I thought I'd share in case anyone wants to try and replicate the results

LET ME KNOW WHAT YOU THINK DOWN BELOW!
Properties:

I would like to suggest that property furniture is separately picked out by the player. For example, in the office a player may want the desk chair, assistant model, and walls from the old spice: warm style, the window shades, glass walls, hallway furniture, desk perimeter tables, and the boardroom cabinets from power broker: polished, and the glass cabinet (the wine sits on top of this), the couch and chairs, and desk from the executive style, the same idea would apply to penthouses and possibly other properties like the facility & hangar where furniture is present and multiple styles are available. I'm sure it would bring great pleasure and satisfaction to me and many others in the community to be able to tweak their properties to perfection. I understand that there is an unused shop by the name of larss & elbo that I come to believe is a high-end furniture store, it could be implemented into the game to "Buy" the furniture from. Additionally, there could be different brands of furniture and appliances, for example, the pc and laptops in properties could be a different brand or type of computer instead of the regular ifruit tech, also the stilt houses have 2 different interiors, allow the player to pick either interior for their stilt houses.
Add a home system in the interaction menu, so players could control the radio or tv without having to interact with them directly. Maybe even have control over the level of lighting, or if they have the right type of shades, allow them to be closed or opened to view the outside of LS.
In the office instead other there being a gun locker and safe in the walls behind the players desk, have the closed room behind the assistant be opened up as an armory to view every weapon the player owns, and the room across from the 3 laptops be opened as a vault and have it filled with cash depending on the funds in the players bank account.
The possibility to own a couple more properties, with all the new cars that will be dripping out every Tuesday, I feel horrible having to sell a good car that I want to keep to make room for a new car and I'm sure others feel the same.
Unlock the balconies in properties, like at the penthouses or stilt houses. Make it so that we can walk out onto the balconies instead of just looking through windows.
Pets being in players apartments and houses/adding animals to GTA online.
More tv shows and movies, or more episodes to existing series. More than just one video game on the office tv, and ability to play video games on TVs in other properties.
Open up the mechanic's area in the back of garages.
Make menus for property radios and TVs so that instead of guessing what channel or station the player is selecting, they can instead use the menu to quickly and easily select their favorite channel or radio station when directly interacting with them.
If mansions or more apartment/penthouse properties are added in future DLC, allow the purchase of extra rooms, like a pool or home theater.
Make the camper available for purchase as a mobile home property.
Make yacht more individually customizable, able to pick out all tents, pick colors and patterns separately, pick helipads, pick individual lighting. Color options wouldn't be limited, it would include all colors. Pick which helicopters and boats are stationed. Open up yacht engine room. Open up the 3rd-floor front exterior.
Add more room for yachts.
Fix interior inclined windows or remove inclined windows on the yacht.
Let doors inside yacht close.
Let security gates in the bunker close and open.
Add more rooms in bunkers.
Let players pick the paintings in properties.

Big downloadable content:

A DLC that would be based mostly on water, it could be business based or heist based. I understand you must get plenty of emails regarding a naval-themed DLC but I would at least like to pitch in my thoughts, I suggest first that either both or one of the two following watercraft be included and available for purchase: 1. The aircraft carrier or a variant of the aircraft carrier that would include aircraft and watercraft storage, a living quarters, an armory, and possibly a section where a battleship (either visually in game or said to be farther out away from the coast) would be ordered to bombard or strike a small section of the map. The explosions would be smaller and less damaging than the orbital strike but there would be 2-3 at once. 2. Bogdan's submarine or a variant of it, it would include mainly the same basic rooms but the aircraft and possibly watercraft storage wouldn't be available, which is why I noted that both could be included. Both would be able to move around the map in a similar fashion as the galaxy super yacht, and both would be own-able at the same time. Second, MK.II weapons and weaponized/non-weaponized watercraft. For the MK.II weapons, I would like to see the grenade launcher, minigun, RPG, sweeper shotgun, micro SMG, and ap pistol. These are just suggestions, you can use whatever weapons you feel should be upgradable. For the weaponized watercraft, two could be variants of the tug and dinghy, the dinghy would have a minigun on the front and the tug would have a huge cannon on the back and miniguns on the sides, maybe a walk-in interior could be opened up on the tug with cannons and miniguns in it. Maybe one of the new ships could be a pirate ship (more on that below), but I'm sure you all would be the experts in finding small warships to put into the DLC. Now depending on if this becomes a business or a heist will vary the features put in: 1. Bogdan's treasure: a small heist could be included involving Bogdan finding an old treasure map and recruiting a team of players to go out looking for the treasure whilst fending off multiple factions of enemies like Merryweather, the army, the FIB/IAA, and maybe the gangs of San Andreas (vagos, ballas, the lost mc etc.) that have also caught wind of the treasure. The heist would be available from the screen in the players facility (it bothers me that there is empty space on the screen when its just the 3 doomsday heists) or from a small island base, some of the freemode setups would include getting various naval ships from one of the many factions to use in mission setups to look for more clues, gather information, or follow the map through sonar or other navigation/detection methods. The finale would include the players finding a cave leading into a cove with a huge pirate ship filled with gold (think the goonies) but on the way there, players would have to fight through the multiple factions that they encountered in previous sections of the heist, at the very end they would blow a massive hole in the side of the cove exposing the ship to the outside of the map and sailing it away in a cinematic cutscene. 2. Marines and pirates: a business similar to the bikegunrunning would be available to the player, on the maze bank foreclosures website a cove (think Hitler's underground cove dock in sniper elite 4 where you kill him or that submarine lair in mechanic resurrection) would be purchasable to the player. Inside of the cove would be the regular rooms like an armory, living quarters, and the main business room, but there would be multiple closed off manufacturing sections that could be unlocked through "Purchasing" them, the computer inside would allow upgrades to be made to each section they're in. The player would gather supplies based on what section they're in, for example, if the player were resupplying the forge, they would go out and use sonar to look for lost gold that could be at the bottom of the sea and bring it back, or steal gold bricks from a shipment on land and bring it back to be melted and sold (like in story mode). A rare resupply encounter could be to steal a pirate ship from Merryweather or the IAA/fib and bring it back. The small island could be where the base of operations is located, or gates and doors would be added to the side of rock walls on the map along the water with a valve hatch being located above for on-foot entry. Bogdan's submarine variant could be stored in here as a moc/avenger type vehicle, while the aircraft carrier is placed outside wherever the player has it.
The nightclubs are opened up and either be a small business headquarters for trafficking or a hang out spot with a couple minigames, perhaps there could be different kinds like the hen house be a strip club and Bahama mamas be just a regular dance club or the player could choose what type of club the property would be. There could be a dancing mini-game be placed near a dance floor along with a fight club of sorts in the basement. It could also introduce Brucie as more than just a contact for bst or bring back a character from another title.
Another heist idea could be that the casino is robbed by the player and his team, they would be hired by Phoenicia rackman to rob the casino because it hasn't been paying its government taxes or something, so the players must take the money by force for her so that the IAA could be funded. The heist could possibly include some variants of that huge tunnel digger to reach the vault room, or the skylift, that could be used to pick up the entire vault and fly it away. It would be the fourth or fifth heist to appear in the heist room in the facility (if the naval-themed DLC above was used for a heist then this would fill the last remaining spot on the heist screen, though I would push for that DLC to be a business since I like the businesses). I don't think gambling would be a feature since it would probably be exploited or glitched, giving players insane monetary gain.
If the naval-themed DLC was used as a business then this heist could be the fifth heist on the screen in the facility. The altruists in Blaine County are taking over and assembling a small army of hillbillies, hobos, members of other various cults (children of the mountain, epsilon program), the O'Neil's, hunters, and possibly the lost mc to attack Los Santos and purge it, Phoenicia rackman has hired the players to infiltrate Blaine county and take back sections and loosen the grip of the altruists with the help of Trevor Philips, the finale is to infiltrate and destroy the altruist camp and end its tyrannical grip on Blaine county. The DLC would be more low-end than most of the recent content but I think some of the community would appreciate lower end content, stuff like pickup trucks and dune buggies and whatnot. Some of the heist vehicles could look like something out of mad max: fury road which I personally think would look insanely awesome, something like an armored bus with machine guns sticking out of the windows.
Civil service DLC: buy police stations and vehicles.
Continental hotel like from john wick.

Game modes & mini-games:

An adversary mode of hide and seek at night with all the lights out, like slasher but on a larger scale. Players would hide in a small section of the map like sandy shores, the player could stay in one spot for about 30 seconds before having to move away from that spot or else they would appear on the map. It could be played in vehicles too since it's in a much larger area, the hiders could be on Sanchez's and the seeker could be in a khanjali tank or weaponized Tampa.
A race mode idea could be something like motocross madness, where the maze bank arena is used for motocross races. There could also be an adversary mode that's a demolition derby or monster truck show.
Add more sports mini-games like bowling, archery, pool, table tennis, and triathlons, possibly add baseball too.
Add a 2 player hunting minigame.
Make official creator props and adversary modes for games such as deathrun, car vs gun, ramp climb.
Let players play mission minigames as video games. Like the doomsday laser hack, and lesters fleeca heist maze hack.

Player customization:

Have there be a gym placed in ls where the player could train their character and upgrade their stats, like the gyms from GTA: San Andreas.
Add more customization for the player's phone.
Make more actions and taunts, its been a while since any have been added.
Make some of the clothing options for male characters available for female characters, for example, the bow-tie that can just be on the male character without the proper shirt or jacket, and make some clothing options for the female character available for the male character, for example, the golden cuffs from ill-gotten gains. Maybe let players purchase the dunce hat too.
Add clothes exclusive or only seen in story mode, for example, the visor that Amanda wears during tennis, franklin's skydiving outfit, Trevors dress, triathlon outfits. Some hairstyles could also be added, for example, Trevor's mullet and beard, Franklin's afro. Additionally, let hairstyles and clothing from holidays be available permanently.
In the character creator, allow the players to change the size of their characters female breasts or male genitalia.
The possibility of this is highly unlikely, but make a no shirt/bikini clothing option for female characters or at least just nipple tape, the strippers are partially nude during lap dances, also the strange blue nipples could be taken care of. I really don't see this being implemented but I see no harm in suggesting it.
Choker chains.
Let players do their own makeup inside their home.
Looping actions or idle actions.
Add backpacks. Something more than parachutes.
Add football helmets, grilled shades, headbands, fezes.
Let players put on duffle bags and other restricted mission outfits.
Let players purchase the wrestler masks.
Let players color and choose the decals for clothes.
Add earbuds.
Bandana’s from bandana masks be separate if the player wants it that way.
Flaming skull masks.
Platform shoes.

Returning content:

Having the little things like free mode money trucks, mechanic vehicle delivery, the fireworks that were placed on the ground, very rare crate drops that held unique items. I understand if this one is a little tricky because they were already in the game but removed, but they could be tweaked. The free mode money trucks could be put in as a free mode event where players go around and try to make the most money off of robbing the trucks (besides, last time I checked there was a tattoo related to robbing trucks, and me being a bit of an "I must have everything" kind of person I feel incomplete to not be able to get that tattoo). For the mechanic delivery, in the vehicle interaction submenu options, it could be set to if the player wants their car personally delivered or just teleported near them. For the fireworks placed on the ground, I would just like to see that re-added into the game, I never got the chance to get any before they were taken but I'm sure I and many, many other players would be thrilled to have them back. As for the rare items that were rewarded from crates, I propose that either the crates be added back with the rare items and past holiday items, or have the items be purchasable but extremely expensive, possibly both.
Bring back assassinating targets for Lester in freeroam.
Add climbing mechanics from older GTA titles and possibly advance it with parkour.

Radio:

When someone has a self-radio, make it so that its not affected when someone changes the radio or if you're the passenger and the driver doesn't have a self-radio station let the passenger listen to theirs, also, I always find that it's never the station that is picked for my moc/avenger, property radio, and sometimes my own personal cars. Additionally, make an option for self-radio in the clubhouse jukebox.
If the player has headphones on then have music playing while they are on foot and in the interaction menu the player could change the radio stations.
Let self-radio play in stores.
Let self-radio play in the nightclub.

Pause menu:

In the report options of a player, allow there to be more specific modder report reasons, for example, some option in a "Modding" tab would be: god mode, money dropping, blame killing, prop spawning, mass killing, organization kicking (where a modder kicks someone from their own organization and makes them wait the 30 or so minutes). Additionally, when a player dies and they are in the menu trying to report, they're kicked out of the pause menu when they die, so when a player dies they can't report, and when a modder is blowing everyone up constantly they cant report them. Have the menu stay open even when the player dies. Also, let players report modding from the social club in case they are kicked by the modder and didn't get a chance to report them.
Let players throw away money so that they don't have modded money.
Let players view how long their friends have been offline.

Business benefits:

Cargo running is slow to fill 5 large warehouses so maybe there would be an option to fill the warehouse in large chunks, say by 10, the player and associates would go find either a semi-truck across the map and go retrieve it facing aggressive enemies the whole way back, or possibly 5 vans with 2 crates inside each van. Another option could be to fill the warehouse completely by going around all of San Andreas grabbing semi-trucks with 10 crates, moving trucks with 5 crates, and small vans with 2 crates inside them, all adding up to 110 crates and the final crate after collecting the 110 crates could be one of the 6 rare special cargo crates. However the buy option would be extremely expensive like perhaps 500 thousand to 1 million depending on how full the warehouse is already, if the warehouse isn't completely empty then the chance to get a rare special cargo would be reduced but if there are already a couple rare cargo in the warehouse then the chance to get another one would only be reduced slightly.
Have an option for the player to hire NPC associates or prospects, they would have tiers like the strike teams in the facility, level 1 would be free, level 2 would cost $5000 an associate, and level 3 would cost $10000 an associate, and they would be paid half their hiring price periodically. That way players don't have to go from session to session hoping someone joins them. The NPCs would be able to help fight and pick up separate cargo crates, they wouldn't be able to take cargo vehicles, they would attack other players based on a setting the player would have for them like the targeting system in the interaction menu, they could target strangers, attackers, or everyone. They would always be by the player's side and get into whatever vehicle they get in. They also wouldn't be able to take sell vehicles by themselves so players would have to hope to get something like the titan or tug if they're full of NPC associates.
Make securoserv associate vehicles like the enduro and the dune buggy CEO vehicles too.
Possibly a progress bar or something in clubhouses and offices to let players know when they've filled the property with a product, cargo, or money "Clutter" so that they don't have to guess and check.
Let CEOs invite members from an mc.
Business to manufacture new weapons for the player and make ammo.
In an organization or mc, if friendly fire is on let members lock on to each other.
Ability to choose organization color if not already taken.
Increase VIP/CEO/pres limit.
Allow players to customize the look and clothing of NPCs in business properties, like the bartenders, mechanics, and assistants.
Allow multiple CEO work missions to be active at the same time.

Crews:

Let players join more than 5 crews.
Give crew leaders the ability to change the crew name when editing their crew, and crew leaders also don't have to level up to 100 in their own crew.
Crew emblems on more clothes.
Let players put crew emblems on guns.
Crew emblems in more properties.

Map expansion/immersion:

Possibly add a small island to the right side of the map. Not as small as the one avi Schwartzman hides on but not as big as a whole map, something with similar beauty and just a bit smaller than great Inagua island from the assassins creed: black flag game. It could be a base for the naval DLC, or maybe if the pirate ship gets added, this is where it would be stored.
Open up fast food places. Like in previous GTA titles, the player was allowed to walk into a restaurant and purchase food to regain health. Possibly also add in fast food vendors around the map for a hot dog or something to quickly replenish health, I understand we have snacks but I feel that it would improve the game, and what if we've run out of snacks?
Open pier carnival games.
More carnival rides, like the drop tower.
Let players buy snacks from places other than the office, facility, or stores.
Let players buy clothes and tattoos from shops along Vespucci beach and on the pier.
Make arcade machines playable.
Add ladders to more buildings to climb on or add a grappling hook.
Let players rob safes in the back of stores.
Have it snow more often.

Annoyance fixes:

Don't force players into cargo warehouses when a crate or cargo vehicle is delivered.
Make an option in mors mutual insurance to claim all cars from all garages
Make older accessories wearable with newer accessories. For example, if I put on original earrings with a lowriders chain, it will remove the chain or earrings
Let players rearrange bicycles in garage bicycle racks.
Allow certain contacts to be blocked from calling or messaging. For example, block ljt from calling about businesses, or block Simeon from giving players a list of cars to bring to him.
Allow the player to disable gang attacks.
Allow players to call the car that's in the moc from office.
Assisted havok landing.
Add an option to stop players from changing the tv or radio.
Let players acknowledge new options in clothing stores and mod shops instead of having to scroll through everything to get rid of the stars.
When exiting a vehicle, don't force the last selected weapon in the vehicle to be the selected weapon on foot.
Let players run in their nightclubs.

Weapons:

Let players buy MK.II ammo in the interaction menu, but they would be very expensive.
Melee weapons on guns (bayonet).
Allow the player to select multiple bomb types at the same time, for example, the incendiary and gas bomb could be selected, so the bomb would create fire and gas. They would only be able to pick one of the two explosive types: explosive or cluster. If they picked three it could be an incendiary gas cluster bomb.
Knuckle dusters on both hands.
Let players buy molotovs, the railgun, the stun gun, and airstrike flares (doesn't bring airstrike)
Lasers on weapons.
Flashbang, decoy, smoke grenades.
Dual wielding pistols.
Burst fire options on certain guns.
MK.III weapons would have branches.
Throwing weapons: ninja star, throwing knives, tomahawk.
MK.II melee weapons or just ammunation upgrades: spikes on the bat, flaming bat, and maybe projectiles like baseballs.
Add flamethrower, a heavy fire ax, sledgehammer, small shields for melee fights, sword, boxing gloves, crossbow/bow, kukri, chainsaw.
Add small sentry turrets that a player can call in for 1 minute before it self-destructs.
MK.II explosives: bouncy, cluster types.
Add cane and umbrella melee weapons that would also change the walk of the character to include the weapon.
Paintball gun for harmless firefights with friends.
Assault rifle with a grenade launcher attachment.
Emp grenades that would disable some explosives like sticky bombs, and jammers that could be placed on surfaces, including cars that would disable explosives until destroyed when shot or player dies.
MK.II tear gas with deadlier gas upgrades and canister upgrades like sticky, on impact.
MK.II grenade launcher with special grenades with fire, gas, cluster, and sticky, or on impact grenades.

Add a device that holds multiple explosives that would activate with proximity, timer, or manual and launch 6 small upgraded explosives.

Add a sort of mini anti-air device that would explode rockets and grenade launcher grenades shot at players.
Stun grenades and mines that would act like a taser.
Small glass shields on guns.
Crossbow bolts with smoke or tear gas.
Scanner for footprints, in freemode it wouldn't matter unless the enemy used off the radar, it would be useful in deathmatch.
Multiple explosive upgrades: on impact cluster flashbang.
Allow players to purchase all ammo when in the interaction menu > inventory > ammo section.
Make the programmable AR purchasable
LMG Bipods
Make the golf club hide-able in the weapons lockers.

Vehicles:

Adding multiple modifications on vehicles, for example, the bodhi has options for vents, side steps, and headlight grills. I'd like it if I had the option to choose all three instead of just one.
If you're reluctant to let us own more properties, then make some of the unpurchasable and rare cars like the Phoenix or manana purchasable so that players won't feel too bad about selling them to make room for newer cars.
Add gogo monkey blista compact, space docker, and the blimp.
Let players customize or at the very least change the colors on pegasus vehicles (i know planes were allowed to be customized in the smuggler's run update, I'm referring to land-based pegasus vehicles).
Add rims that spin, like if there were a fidget spinner on the outside of the rim. Let tire designs be available on any type of rim, for example, the white walls of lowriders rims being on muscle tires.
Make plane windows tintable
Add more rims from cars with unique rims.
Roof options on the ruiner.
Assisted yacht helicopter landing.
Able to call bicycles from office or mechanic.
Speed racer type of cars with jump jacks and unique weapons.
Hot wheels type cars.
In the vehicle remote functions, let players roll their cars windows up and down.
Allow players to upgrade and customize the car that comes with the anti-aircraft guns.
Pegasus semi-trucks with trailers.
Add zeppelins and war blimps, like from guns of Icarus.
In garages or workshops, place a spinning display platform for a car to be showcased.
Let players transfer cars between garages without manually driving them.
Let players change the avenger propeller light color.
Colored sun strips on cars with sponsored sunstrips only.
Purchasable trailers for cars like the boat or generator trailers.
Let players put spoilers on the ramp buggy.
Let players modify the other 3 special vehicles in the vehicle warehouse.
Make the Speedo, Mule, and Pounder Custom more explosive resistant.

Contacts:

Ability to call Lester and have him make another players phone ring and not able to shoot before ending the call would take about 3 seconds to end it.

Job creator:

Make pipes in stunt races that can go underwater.
