According to internet chatter, a teaser trailer for 2K Marin's sequel to the critically acclaimed shooter has been discovered. CVG is reporting that a teaser for the upcoming sequel unlocks within the menus of the PlayStation 3 version when the game is completed. The trailer opens with a title card that reads "Atlantic Ocean" and pans away from a Big Daddy stuffed animal being held by, what looks like, a grown up Little Sister as she looks off into the water. Pillars then begin to form around her and the title screen reveals the name "Bioshock 2: Sea of Dreams."
Joystiq has contacted 2K Games for confirmation on the game and trailer.
