Bioshock Infinite: Burial at Sea
First mentioned by EscapeGoat
Like Undead Nightmare, Burial at Sea is really only tangentially related to the game it's attached to. It's set in the underwater city of Rapture from the first Bioshock, but stars the characters of Bioshock Infinite. Taking place a year before the events of the first game, Burial at Sea features Elizabeth as a femme fatale who hires Rapture-based private eye Booker Dewitt find a missing girl, leading to adventures, flashback, and more. In the second episode, you take control of Elizabeth as she continues her pursuit of the missing girl. It's a noir-themed private eye tale filled with plasmids and eve. Episode Two even features a 1998 mode, in which you're trying to complete the chapter using only stealth and non-lethal attacks.
