BioShock Infinite developer Irrational Games has confirmed that Burial at Sea - Episode 1 will launch for PC, PlayStation 3 and Xbox 360 on 12th November.
The first slice of a two-part Rapture-based DLC story, Burial at Sea will see Infinite's leading characters Booker and Elizabeth somehow recast in the series' original setting of Rapture.
How they've ended up there - and what they know of Infinite's events - will play a key role in the story. You'll also get to see Rapture before its fall into anarchy, and meet up with a memorable face from the original game.
A new Plasmid - the icy Old Man Winter power-up - new gear and the ability to once again switch weapons from a weapon wheel are among the other highlights.
Burial at Sea - Episode 1 will cost £9.99, or is available as part of BioShock Infinite's £15.99 season pass alongside the game's second episode and wave-based arena add-on Clash in the Clouds.
