The year is 1912. A floating city called Columbia has been drifting above the clouds since 1893 and has become a nation of its own, built on American exceptionalism and religious fervour. Booker DeWitt is a disgraced Pinkerton agent sent to retrieve a woman named Elizabeth from it. He finds a city on the edge of civil war and a young woman who can open doors in reality itself.

BioShock Infinite is a first-person shooter set in the airborne city of Columbia, designed around the complementary pairing of Booker's conventional gunplay with Elizabeth's Tear ability — the power to pull objects, weapons and allies from alternate timelines into the current moment. Vigors replace BioShock's Plasmids as the game's supernatural powers, allowing Booker to send crows, throw electrical charges, possess machines and combine effects. Sky-Lines are roller-coaster-like freight rails connecting Columbia's floating platforms, used for movement and combat positioning. The game's narrative is its defining achievement: Columbia is a fully realised ideological world with its own history, mythology and propaganda, and the story it tells about American exceptionalism, racism, religious fervour and the nature of choice builds to one of the most discussed endings in the medium. Burial at Sea, a two-part DLC set in the original BioShock's Rapture, continues the story.
