The sole survivor of an oceanic plane crash, you swim to a lighthouse. Inside you discover a bathysphere and descend to the seafloor where arch-capitalist Andrew Ryan’s city sits. Volcanic vents fuel its sprawling Art Deco facilities. Economic liberalism spurred its leading citizens to innovate in the name of prestige and profit; the gene-altering drug ADAM granted them unbelievable abilities and then drove them mad. Saving your skin could cost you your humanity; returning to the surface means delving deeper into the city of Rapture’s sordid history.
