If you've got some time to kill you might want to head over to the Bioshock 2
as 2K has started to populate the site with content. There's some interesting images on the site include what looks to be a new protector (maybe Big Sister?) as well as a few other clues to the existence of some other kind of underwater facility. I know the original holds a special place in the heart of a lot of gamers so it will be interesting to see what 2K Games does with the game.
