The first BioShock 2 teaser trailer has been uncovered by VG247. The video is unlocked after you complete the new PlayStation 3 version of BioShock. It shows a more grown up Little Sister with Big Daddy plushy in hand, standing at the Atlantic Coast staring out into the ocean as a city (that looks like Rapture) emerges from the beach floor.
The game has received a subtitle as well, now being called BioShock 2: Sea of Dreams. The FPS survival-horror sequel will likely appear on Xbox 360, PlayStation 3 and PC and has been confirmed for release in August 2009.
