BioShock is a first-person shooter developed by Irrational Games and released in 2007. Set in the underwater city of Rapture, players assume the role of Jack, a plane crash survivor who uncovers the city’s dystopian collapse. Combining gunplay with genetic modifications known as Plasmids, the game allows players to wield elemental powers alongside traditional weapons. Its atmospheric world-building, moral choices involving Little Sisters, and philosophical themes about objectivism and control helped redefine narrative-driven shooters.
