2K Boston & 2K Australia. (2007). BioShock [Video game]. 2K Games.

BioShock is a 2007 first-person shooter developed by 2K Boston (later Irrational Games) and 2K Australia, and published by 2K Games. Set in 1960, the game follows protagonist Jack, who discovers the underwater city of Rapture—a supposed utopia created by business magnate Andrew Ryan to escape government and religious oversight. The city's decline began with the discovery of ADAM, a genetic material granting superhuman abilities, leading to societal collapse and the rise of hostile mutants known as Splicers.

The gameplay combines traditional shooter elements with role-playing mechanics, offering players a variety of approaches to combat and exploration. Players can wield conventional weapons and utilize Plasmids—genetic modifications that bestow powers like telekinesis and pyrokinesis. This system encourages creative strategies, such as electrifying pools of water to incapacitate multiple enemies simultaneously. Additionally, players can hack security systems and turrets to turn Rapture's defenses against adversaries.

A notable aspect of the game is the moral choice system involving Little Sisters—young girls who harvest ADAM from corpses. Players can choose to rescue or harvest ADAM from them, impacting the game's narrative and ending. This ethical decision-making adds depth to the gameplay, influencing character interactions and story outcomes.

BioShock's development was led by Ken Levine, who drew inspiration from 20th-century dystopian thinkers like Ayn Rand and George Orwell. The game's art direction features a distinctive art deco style, enhancing its atmospheric and immersive experience. Upon release, BioShock received critical acclaim for its narrative, thematic depth, and visual design, and is often cited as a landmark title in video game history. It has since spawned two sequels: BioShock 2 (2010) and BioShock Infinite (2013), further expanding the franchise's exploration of complex philosophical and social themes.
