BioShock Infinite’s first proper DLC pack – dubbed Clash in the Clouds, if you’re curious – may be a disappointing arena-based combat affair, but publisher 2K Games has softened the blow by revealing the title’s two-part story expansion Burial at Sea, which will take you back to the depths of Rapture later this year.

The episodic content will star both Booker DeWitt and Elizabeth, and will allow you to plunge into the underwater city before its collapse in 1958. You’ll play as the private detective in the first instalment and the femme fatale in the second. Additional details are scarce, but director Ken Levine told Eurogamer.net that developer Irrational Games is not cutting any corners.

“When we started this, we really tried to listen to the fans, and to us the fans were clearly saying to us, ‘Look, we want the A-team on the DLC, we want the same team who did the actual game,’” he said. “So basically the day that we finished – literally, pretty much the day that we finished Infinite – we went to work on the DLC, starting pretty much from scratch on the game content."

There’s a trailer embedded below which gives a pretty enticing account of what you can expect from the upcoming expansion pack. The add-ons will cost £9.99/$14.99 apiece, or will be available as part of the title's season pass. Are you eager to go swimming in the sea of corruption again? We’re feeling giddy just thinking about it, to be honest.
