Once you’ve grabbed one of the lasers and can’t lose your wanted level on your own, head to the location in the image above. This is the entrance to the sewer from when you scoped out the casino. Go there and hide inside underground until your wanted level dissipates.
Drive ahead and you’ll come across the security check point. After a couple of seconds, you’ll proceed through and need to park the van in the marked spot. Once you reach the morgue, search valet’s body and get the keycard. Park your vehicle right in front of the entrance as it will be useful later on when you’re exiting.

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.
Big Con Prep
After you exit to the outside, you should be right https://rt-roofing.co.uk/ 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), 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.

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.
Splitting tasks efficiently ensures mission completion will be effortless. For optimal results, equip a weaponized helicopter—or the **Oppressor Mk II** if available. The **NOOSE** outfit grants immunity from **NOOSE** agents upon exiting the casino. The whiteboard’s *Approach Specific Preps* section requires selecting *Exit Disguise*. Driving away in the truck will trigger a **3-star** bounty. My solution: head to the image’s marked spot to eliminate the issue.
Scoping out the Casino – Scope every entrance and POI
For aggressive, again, patrol routes make it easier but are never necessary. 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.
When you are choosing a gunman — there’s no need to spend any time deciding which one to choose as this heist is the silent and sneaky approach! You shouldn’t expect a lot of altercations and combat situations. Therefore, we recommend you choose KARL ABOLAJI who takes only 5% from the final cut.
