Kokatu is hinting that an unnamed source has told them that Bio Shock 2 might feature Big Sisters instead of the Big Daddys that made us go so mental in the first game.

If you look at the picture posted this weekend on the games teaser sitethere are some fairly noticeable differences between the doll there and the lumbering lunatics from the first game. The newspaper article that describes the missing girl’s abductor (you have been to the site right) says the abductor is tall and fast….hmmm

Kokatu went on to explain that their mystery source told them the Big Sisters would be Amazonian versions of the Big Daddies from the first game.

The Game Developers Conference is only a few short weeks away, so I’m pretty sure we’ll be seeing more of the Big Sisters.
