About III Online

III Online brings the legendary open world experience of Liberty City directly into your browser. Set in a gritty, living 3D metropolis, the city stands as a landmark in open-world gaming history.

The story follows Claude, a criminal who is betrayed and left for dead during a bank heist in Liberty City. After escaping from a police convoy transport, Claude dives deep into the underworld of the city, taking on contracts for rival gangs, corrupt officials, and syndicates to seek his revenge.

Navigate the three districts of Liberty City — Portland, Staunton Island, and Shoreside Vale — with full freedom, classic vehicle handling, authentic radio stations, and open-ended mission structures.
