Grand Theft Auto III revolutionized the gaming industry in 2001 by introducing a fully realized, 3D sandbox metropolis. The story follows Claude, a silent criminal betrayed and left for dead by his girlfriend Catalina during a bank heist. After escaping a prison transport convoy, Claude dives into Liberty City’s gritty underworld, taking on contracts for rival mafias, corrupt cops, and cartels to fuel his revenge.
