Advanced stealth method discovered by the GTA6Copilot team. Zero wanted stars, maximum payout — full step-by-step walkthrough for Pro members.
The GTA 6 Underground Casino Heist is a hidden alternative to the main Diamond Casino job, discovered by digging through the casino’s basement network rather than the main vault floor. Its biggest draw is that it can be completed without triggering a single star of wanted level if you follow the correct route.
Reaching the underground vault requires accessing a maintenance tunnel from an adjacent parking structure, bypassing the casino’s main security entirely. Once inside, timing your movement between patrol rotations lets you clear the entire heist without alerting a single guard, which is the key to keeping your wanted level at zero throughout.
Successfully completing the Underground Casino Heist nets a payout of roughly $4.8 million, making it one of the most lucrative zero-star scores in the game. Because the heist can be repeated after a cooldown period, it has quickly become a favorite among players looking for a reliable, low-risk source of late-game income.
