BioShock is a first-person shooter video game developed by 2K Boston/2K Australia—previously known as Irrational Games—designed by Ken Levine. It was released for the Windows operating system and Xbox 360 video game console on 21 August 2007 in North America, and three days later in Europe and Australia. A PlayStation 3 version of the game, which was developed by 2K Marin, was released internationally on 17 October 2008 and in North America on 21 October 2008 with some additional features. The game was also released for the Mac OS X operating system on October 7, 2009. A version of the game for mobile platforms is currently being developed by IG Fun. A sequel, BioShock 2, is scheduled for release on February 9, 2010.

Set in an alternate history 1960, the game places the player in the role of a plane crash survivor named Jack, who must explore the underwater city of Rapture, and survive attacks by the mutated beings and mechanical drones that populate it. The game incorporates elements found in role-playing and survival games, and is described by the developers and Levine as a "spiritual successor" to their previous titles in the System Shock series.

The game received overwhelmingly positive reviews, being particularly well-reviewed in the mainstream press, which praised its "morality-based" storyline, immersive environment and Ayn Rand-inspired dystopian back-story.
