Kill the agents, lose the cop and head to FIB building. If you get a mission where you need to go to the FIB building, you will first have to go kill some agents and get the FIB agent pass so you can impersonate that agent. The first one requires you to get it from the N.O.O.S.E headquarters, while the second will have you grabbing it from the FIB building. When you go for the hacking device, you can expect two different locations where it will be located.
So we recommend AVI if he's unlocked for you, otherwise, go with PAIGE. Trust us when we say this, those 15 seconds are a lot when you're emptying the vault. If you choose AVI, you will get an extra 15 seconds giving you a total of 3 minutes and 30 seconds. If you choose PAIGE, you will get a total of 3 minutes and 15 seconds in the vault and she takes 9% of the cut.
If you want to know how to unlock Avi Schwartzman you can check our full guide here. Choose either PAIGE HARRIS or AVI SCHWARTZMAN if you've unlocked him. You need to make sure you choose the best hacker in the list since the time you get inside the vault is based on the hacker you choose. Karim Denz on the prep board HackerĬhoosing a hacker is the most important thing in this whole prep.
Also, if you do decide to use the vehicles, makes sure you upgrade them to Level 3 in the arcade garage, by sitting in the car and upgrading them. For the vehicles, in case you decide to use the getaway cars (which you do not need if you're following this guide) you can choose the Sentinel Classic getaway vehicles.
But hiring a driver is mandatory therefore you can choose KARIM DENZ who only takes 5% cut. You do not need your driver either, since you won't be using the getaway vehicle for this approach. Do not choose the shotgun loadout as it does little to no damage. When you choose the weapons, make sure you choose the Micro SMG loadout in case the heist doesn't go as planned. Therefore, you can choose KARL ABOLAJI who only takes 5% cut. You will be using disguises to make your way in and out and shouldn't need any weapons. It will be a simple "in-and-out" approach. You do not need to worry about choosing the best gunman for this approach since you won't be getting into combat situations. You can also do the prep missions in either public or solo sessions. Having said that, it is not impossible to do the prep missions on your own. However, doing them with at least one friend will make things much faster and easier for you. Note that you can do all these heist prep missions either solo or with your friends.
What is the difference between the Level 1 and Level 2 security passes?.Is there an easier way to get the NOOSE outfit?.Do you need to buy the penthouse to carry out the Diamond Casino Heist?.Since there are many setup missions and heist prep missions, we will show you the most optimal setup for The Big Con approach so that you don't have to do all the missions, only the necessary ones, resulting in the most efficient use of your time and the best outcome. As the name suggests, you con your way into and out of the casino using various disguises. One of the three approaches is called The Big Con approach (the others being the Aggressive and Silent and Sneaky approaches). Having different approaches to the new casino heist is one of the major new features added to GTA Online via the DLC. Make sure you also check out how to unlock the elite hacker Avi Schwartzman for more time in the vault, our heist payout guide, and also the POI and access point guide. There is also a variant of this approach which uses Yung Ancestor disguises instead and you can read how to do that here.
Our Silent and Sneaky guide can be found here and our Aggressive approach guide is here. This guide is a complete walkthrough of the Big Con approach to the Diamond Casino Heist.
