The BioShock series is a collection of story-driven first-person shooters in which the player explores dystopian settings created by Ken Levine and his team at Irrational Games. The first two games, BioShock and its direct sequel, BioShock 2, take place in the underwater city of Rapture in 1960 and 1968, which was influenced heavily by Ayn Rand's Objectivism. The third installment, BioShock Infinite, is set aboard the floating air-city of Columbia in 1912, designed around the concept of American Exceptionalism. Though Infinite is not a direct sequel to the previous games, the game is thematically linked; a short scene within the core Infinite game returns to Rapture, while the downloadable content BioShock Infinite: Burial at Sea tie in many of the plot elements between BioShock and BioShock Infinite.

As a heavily plot-driven series of games, BioShock contains a long list of non-playable characters (NPC) with which the player interacts and which drive the games' respective stories.
