BioShock is a 2007 first-person shooter game developed by 2K Boston (later Irrational Games) and 2K Australia, and published by 2K. The first game in the BioShock series, it was released for Microsoft Windows and Xbox 360 platforms in August 2007; a PlayStation 3 port by Irrational, 2K Marin, 2K Australia and Digital Extremes was released in October 2008. The game follows player character Jack, who discovers the underwater city of Rapture, built by business magnate Andrew Ryan to be an isolated utopia. The discovery of ADAM, a genetic material which grants superhuman powers, initiated the city's turbulent decline. Jack attempts to escape Rapture, fighting its mutated and mechanical denizens, while engaging with the few sane survivors left and learning of the city's past. The player can defeat foes in several ways by using weapons, utilizing plasmids that give unique powers, and by turning Rapture's defenses against them.
