There's an unexpected surprise waiting for gamers at the end of the PlayStation 3 version of BioShock: A trailer for BioShock 2.
The trailer for the game, known in full as BioShock 2: Sea of Dreams, shows what's presumably a Little Sister holding a home-made Big Daddy doll as she gazes out over the Atlantic. No in-game action is shown, but the waterlogged BioShock 2 logo at the end of the clip is strong evidence that the sequel will take us back to the cold depths of the ocean. (Yeah, I know, what a shock.)
BioShock 2 was announced back in March 2008, but as far as I know this is the first anyone has seen of the game's actual progress. The game is being developed by the new 2K Marin studio rather than the original team at 2K Boston (with help from 2K Australia, of course), and while Creative Director Ken Levine will apparently be involved with the project, at last check it was unclear exactly what form that involvement would take. The game is targeted for release in fall 2009.
The BioShock 2 promo trailer is available on YouTube.
