Scope out the Diamond Casino ahead of the big score.
The GTA 6 Casino Recon mission begins the buildup to the game’s signature Diamond Casino Heist, sending Jason and Lucia undercover to scope out the casino floor, security office and vault access points. This mission favors patience and observation over direct confrontation.
You will pose as guests to walk the casino floor, using a hidden camera to tag security cameras, guard positions and staff-only doors. Completing optional side objectives, like cloning an employee’s keycard, will make the eventual heist significantly easier to plan and execute.
Finishing Casino Recon rewards a detailed security blueprint and unlocks the Diamond Casino Heist mission, one of the biggest scores in the entire campaign.
