"Grand Theft Auto IV" (also known as "GTA IV") is an action game developed and published by Rockstar for PC, Xbox 360, and PlayStation 3. The game features two additional episodes (or expansions): "The Lost and the Damned" and "The Ballad of Gay Tony."
Like other "Grand Theft Auto" games, "GTA IV" features both a storyline and an open world, offering a somewhat sandbox style environment for players to explore. Third-person combat, morality and law systems, and vehicles play a major part in the game's style and replayability. The game also offers over a dozen types of multi-player modes.
