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

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Power drills: You wanna get it if you think there is enough time to hit deposit boxes AFTER grabbing all the main stuff.
7. 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.
8. Acquire masks: A complete waste of time.
9. 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

1. 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.
2. Driver: Hire the cheapest guy, period.
3. Hacker: Hire Paige or Avi.
4. 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.
5. 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.
6. 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.
7. Duggan shipments: Not necessary at all! Since no shots will be fired, their protective gear doesn't do any use against knocking out.
8. Power drills: Same as other approaches.
9. Security passes: LEVEL 2!
10. 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

1. 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.
2. Driver: Do I need to say that again?
3. Hacker: Yeah one of those two.
4. Patrol routes: Nobody cares because it will be loud.
5. 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!
6. Power drills: There is less time in vault so I usually skip this unless it's a crew of 4.
7. Security passes: If you don't get a level 2 pass then you are out of your mind.
8. Acquire masks: Literally no one cares.
9. 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.
10. 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!

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.

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:

1. Leave the camera
2. Call Lester WHILST STILL IN THE CASINO
3. Cancel the Casino Heist
4. Leave the Casino and go back to your arcade
5. 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.

1. Go up to one and press E to start collecting the gold.
2. Collect every bar but stop at the last one
3. Press right click to stop the looting whilst there is still loot on the cart
4. Wait 2-3 seconds infront of the cart
5. 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:

1. 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:

1. 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
2. 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.
3. 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:

1. 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.

​

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!)
