Bioshock Infinite is getting its head out of the clouds and heading back to the briny deep for its newly announced “Burial At Sea” DLC. The two-part add-on will feature Booker DeWitt and a sultrified Elizabeth investigating Rapture before its collapse.

Part one of “Burial” has players solving problems and killing Splicers as Booker DeWitt, and features combat and plasmids that are reminiscent of the original Bioshock. Part two puts you in Elizabeth’s shoes and, according to creative director Ken Levine, is more survival-horror than two-fisted action.

The game’s story means to shed more light on Rapture’s history, and let players experience the city in a transitional period between utopia and dystopia.
