About theGTA 5 Diamond Casino Heist The Big Con

Frankly speaking, the Big Con approach revolves around a special scenario, in which players disguise themselves to gain access to the Casino’s basement and steal the loot. At the end of the heist, players can optionally choose to take advantage of a new disguise to shy away from the guards during the getaway or even fight for an escape.

The Big Con approach is no doubt different from the other aforementioned approaches as this method comes with a unique entry in exchange for maintaining their cover. Once you fail to keep your disguise any longer, you must switch to a more aggressive method!

Note that the Ceramic Pistol will be the secondary weapon by default in all weapon loadouts in the Big Con, making sure that you’ll bypass the metal detectors without a hitch.

Bonus: When using the Bugstars disguise, Lester mentions that he had 'pulled something similar to take down a jewel store.' This references The Jewel Store Job, particularly the Smart approach, thereby making it the canon approach.

When you and your crewmates succeed in getting your hands on the vault, you have to drill the door locks to open it then get the loot as soon as possible. Try to not trigger the failsafe or you’ll activate the nerve agent in return.

Level 1 is actually useless. In addition, Level 2 cards allow you to enter through all the doors without the need to hack them. With Level 1, you will need to hack doors to get through them. It makes your heist much easier especially if you are doing a silent and sneaky approach.

Soon afterward, you have to get out of the vault as well as the casino. Just try your best to avoid being noticed by the guards and the police as they’re all alerted.

GTA 5 Diamond Casino Heist The Big Con - Exit Points


Players are allowed to decide how to exit the casino through one out of the five entry points from the remaining approaches. For instance, if you opt for the helipad or roof terrace exit point, you’ll be on the lookout for Parachutes at these places.

Otherwise, players can choose to enter the laundry room if they’re remaining undetected. The crew can equip themselves with either the NOOSE uniform (in case you’ve had the NOOSE Gear prep completed) or the High Roller set (if you’ve obtained the 54 Playing Cards).

The laundry room is also where the crew can find the main weapons, which are based on specific loadouts. It’s time to escape without drawing attention from the guards.

The outside area is now surrounded by NOOSE and LSPD officers, so the players must avoid them by all means to not only move towards the getaway vehicles but also get rid of the current wanted level.

If all the crewmates cannot remain undetected, they’ll instead have to face off against the police. To complete the Casino Heist, the crew needs to drive to the buyer’s location.
