The game is played from a third-person perspective and its world is navigated on-foot or by vehicle. Throughout the single-player mode, players control Niko Bellic. An online multiplayer mode is also included with the game, allowing up to 32 players to engage in both co-operative and competitive gameplay in a recreation of the single-player setting. Two expansion packs were later released for the game, "The Lost and Damned" and "The Ballad of Gay Tony", which both feature new plots that are interconnected with the main "Grand Theft Auto IV" storyline, and follow new protagonists.
