arcticstoat writes "If you've played Bioshock, you'll know it can be a tough choice deciding whether you're going to kill the cute (yet evil looking) Little Sisters and extract their ADAM, or let them live. Your choice even affects whether you're given one of three possible endings of the game, and their story will now continue to be told in the sequel. 2K Games has just released a trailer for the new game, showing what appears to be a grown up Little Sister, still clutching a toy, while the city structure of Rapture springs up around her. No gameplay is shown, but it does give a hint as to what the game will be about, and it looks as though the game may take you onto dry land." Gamespot initially confirmed the trailer's authenticity after it was leaked last week. A representative from 2K Games also mentioned Bioshock 2 was "destined for the PlayStation 3, Xbox 360 and Windows PC platforms."
