Irrational followed up Bioshock Infinite with two expansions. Bioshock Infinite: Burial at Sea features a return to Rapture and the world of Andrew Ryan through the eyes of Booker and Elizabeth. Released in two parts, Burial At Sea Episode 1 is a more conventional experience, whereas Episode 2 tries (and fails) to break the Bioshock mold.
The first episode features a more adult, jaded and seductive Elizabeth visiting Booker in Rapture. She gives him a job to find a Little Sister. There are references to the original Bioshock,as well as some cameos, but it's a pretty standard affair. The mechanics are the same as those of the base game and there's not much story to speak of. If 1930s adventure serials inspired Bioshock Infinite, then film noir-inspired Burial At Sea 1.
