GTA Online Diamond Casino Heist Setup Guide: Approaches, Access Points of Interest, Support Crew

If you’ve secured a laser and your wanted level isn’t dropping on its own, proceed to the marked spot in the provided image. This is the sewer entrance you scouted during your initial casino inspection. Enter the underground area and remain concealed until your wanted level decreases naturally.

Continuing forward, you’ll encounter the security checkpoint ahead. After a brief moment, you’ll pass through and must park the van in the designated space. Upon arriving at the morgue, examine the valet’s corpse to obtain the keycard. Position your vehicle directly in front of the entrance—it’ll be beneficial when exiting later.

Now it’s time we move on to the next section of this guide. Much like the unmarked weapons mission mentioned earlier, this setup mission can task you with one of several different objectives.

After you exit to the outside — you should be right next to the race track. There will be plenty of NOOSE agents here, so make sure you have body armor on. As for the next mission, we are going to need to grab the vault drills. Interestingly, we won’t actually be using them in the heist with the Gruppe Sechs method. But we still need to complete the mission never-the-less to complete the heist. Out of all the different heists that have been added to GTA Online over the years, my favorite is without a doubt the Diamond Casino heist!

At this location is a police helicopter — which you can use to escape the police. For a detailed walkthrough on how to get to it, please check out this video here made by YouTuber Gtamen. Once you climb up the building and both you and your partner get inside the chopper, simply fly to the yellow dot shown on your map. Avoid any other police helicopters and stay high in the air while you fly there. Take a left and walk down the hallway until you reach another hallway leading to the left. There should be a guard patrolling down this second hallway.

Which support crew should you choose for the Diamond Casino Heist?

Repeat this process until all the locks are broken and enter the vault. Firstly (when it comes time to do the fingerprint scanner hacking), https://rt-roofing.co.uk/ the pattern that you will see on one door will be the same for all the doors that you hack inside. Make sure you and your friend are in sync and have already decided who will take which side. For instance, you can take out the left guard and your friend can take out the right one. Once you’ve taken out the guards proceed through to the double doors ahead of you.

Understanding the scoping part of The Diamond Casino Heist in GTA Online

The guards on the other side can’t see you, so don’t fret about them. While they do that, you should head to the farthest point away from the vault door. Don’t worry about the guards inside, they also can’t see you through the glass. After you leave the vault, breathe a sigh of relief because you now have a checkpoint! Continue back through the corridor and get to the security checkpoint again.

As long as you stay clear of the police, by the time you reach the next objective your wanted level should disappear. Next on this full walkthrough for how to do the Diamond Casino Heist in GTA Online, we have the vault explosives prep mission. Go back to the whiteboard you were at for the last mission and select the option to the right of the thermal charges mission. Once the mission launches, you’ll need to head to a location off the coast of the map where you can salvage some explosives.

If you divide the work this way, completing the mission should be no problem. I recommend using a weaponized helicopter or an Oppressor Mk II if you have it. Just know that the NOOSE outfit has the benefit of making NOOSE agents friendly to you when you first leave the casino. Go to the Approach Specific Preps section of the whiteboard and select Exit Disguise. After you get in the truck and drive away — you should have a 3-star wanted level. I’ve found that the best way to get rid of it is to drive to the location shown in the image below.

Aggressive patrol routes simplify navigation, though they’re not essential. While you can attempt this solo, teaming up will make it significantly simpler. If you fail to collect all items (simply exit the game), and you’ll be able to restart the mission. Wearing reinforced armor increases your damage tolerance, so I’d suggest using it despite the speed reduction.

When selecting a gunman, no deliberation is needed—this heist demands stealth over firepower! Combat engagements are minimal — so expect few confrontations. Consequently, we advise picking **Karl Abolaji**, who only deducts 5% from the final payout.
