Bioshock 2: New Details - New Enemy - 'Big Sister'

Lots of lovely new detail has been revealed about Bioshock 2, in which you get to play the original Big Daddy, looking after a very grown up little sister called Eleanor. A new adversary has cropped up in Rapture, she's called Sofia Lamb. Not only that but the ten years on from the original game, the splicers have grown less human, but have grown in intelligence... and speed. See the fun in the video below.
