BioShock Infinite's anticipated return to Rapture will hop into a submersible on November 12, Irrational Games has announced. Burial at Sea, the first story-based downloadable content, will tell an alternate take on Booker and Elizabeth, this time as the pair inhabit the sprawling underwater mega-city from the first BioShock game.

The tweet that announced the date was sure to note this is just episode one, as the DLC has been split into two parts. Players will control Booker for the first part, and Elizabeth for the second. As previously reported, the two packs will cost $15 apiece, but you can get them both (plus some extra goodies) with the $20 Season Pass.
