BioShock Infinite: Burial at Sea - Episode One

Come back to Rapture in a story that finds Booker and Elizabeth on the eve of the underwater city's fall from grace. Developed by Irrational Games, the developer of the original BioShock and BioShock Infinite, this DLC features Rapture as you've never seen it before-a shining jewel at the bottom of the ocean, built almost entirely from scratch in the BioShock Infinite engine. Gameplay has been modified to give the player an original BioShock combat experience that merges the best parts of BioShock and BioShock Infinite: new weapons, new Plasmids/Vigors, Tears, Sky-Lines, and Big Daddies.
