GTA III is set in modern Liberty City, a fictional metropolitan city. The game follows a nameless criminal who was betrayed by his girlfriend in a bank heist, and is required to work his way up the crime ladder of the city before confronting her. GTA III is comprised of elements from driving games and third-person shooters, and like its predecessors, implements sandbox-like gameplay, where the player is given the freedom to explore a large city, complete missions, commit criminal acts, or complete side missions.
