BioShock is a first- person shooter video game developed by 2K Boston (later Irrational Games ) and 2K Australia, and published by 2K Games. The game 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, and an OS X port by Feral Interactive in October 2009. A mobile version was developed by IG Fun. The game's concept was developed by Irrational's creative lead, Ken Levine, and incorporates ideas by 20th century dystopian and utopian thinkers such as Ayn Rand, George Orwell, and Aldous Huxley, as well as historical figures such as John D. Rockefeller. The game is considered a spiritual successor to the System Shock series, on which many of Irrational's team including Levine had worked previously.
BioShock is set in 1960. The player guides the protagonist, Jack, after his airplane crashes in the ocean near the bathysphere terminus that leads to the underwater city of Rapture. Built by the business magnate Andrew Ryan, the city was intended to be an isolated utopia, but the discovery of ADAM, a genetic material which can be used to grant superhuman powers, initiated the city 's turbulent decline. Jack tries to find a way to escape, fighting through hordes of ADAM -obsessed enemies, and the iconic, deadly Big Daddies, while engaging with the few sane humans that remain and eventually learning of Rapture's past. The player, as Jack, is able to defeat foes in a number of ways by using weapons, utilizing plasmids that give unique powers, and by turning Rapture's own defenses against them.
