The add-on to BioShock Infinite, which launched in March, should be out "before the holiday." Irrational is still stamping a date on episode two.
Part one of the narrative-driven expansion set tells a new story of Booker DeWitt and Elizabeth in the underwater city of Rapture. Gameplay is more in line with the original BioShock. Part two focuses on bringing closure to Elizabeth's story.
Both DLC cost $15 each and are part of the game's season pass.
