Casino Heist Sewer Tunnel Access Guide
The sewer tunnel route in casino heist missions provides an alternative entry point that avoids main-floor security. Players must first locate the tunnel access panel near the construction site, then navigate the underground maintenance corridors to reach the casino vault area.
This path requires specific equipment and timing. Live casino tables are not part of the heist mechanics, and bonus funds cannot be used for in-game purchases. Standard withdrawal rules apply to any real-money winnings from related promotions.
