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, fighting ADAM-obsessed enemies and Big Daddies, while engaging with the few sane people that remain and learning of Rapture'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.
BioShock'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 Jr. and Walt Disney. The game includes role-playing elements, giving the player different approaches in engaging enemies such as by stealth, as well as moral choices of saving or killing characters. Additionally, the game borrows concepts from the survival horror genre, notably the Resident Evil series. BioShock is considered a spiritual successor to the System Shock series, on which many of Irrational's team, including Levine, had worked previously.
BioShock received universal acclaim and was particularly praised by critics for its narrative, themes, visual design, setting, and gameplay. It is considered to be one of the greatest video games ever made and a demonstration of video games as an art form. BioShock was followed by two sequels, BioShock 2 and BioShock Infinite, released in 2010 and 2013, respectively. Ports of BioShock were released for macOS and mobile following its console releases. A remastered version of the game was released on Microsoft Windows, PlayStation 4, Xbox One, and Nintendo Switch as part of BioShock: The Collection.
BioShock takes place in Rapture,[5][6] a large underwater city planned and constructed in the 1940s by individualist business magnate Andrew Ryan, who wanted to create a utopia for society's elite to flourish outside of government control and "petty morality". This philosophy resulted in remarkable advances in the arts and sciences, which included the discovery of "ADAM": a potent gene-altering substance which is created by a species of sea slug on the ocean floor. ADAM led to the creation of "Plasmids", mutagenic serums that grant users super-human powers such as telekinesis and pyrokinesis. To protect and isolate Rapture, Ryan outlawed any contact with the surface world.[7]
As Rapture flourished, wealth disparities grew, and criminal Frank Fontaine used his influence over the disenfranchised working class to establish illegal enterprises and obtain power—enough to rival Ryan. With doctors Brigid Tenenbaum and Yi Suchong, Fontaine created his own company dedicated to researching plasmids and gene tonics. As ADAM became addictive and demand skyrocketed, Fontaine secretly mass-produced ADAM through slugs implanted in the stomachs of orphaned girls, nicknamed "Little Sisters". Fontaine was killed in a shootout with police, and Ryan took the opportunity to seize his assets, including control of the Little Sisters.
