We first caught a glimpse of this at the end of the first game on the PS3, at that time it was going to be called 'Sea of Dreams'. Bioshock 2 is set in the same underwater city of Rapture but this time you play the Big Daddy, how cool is that? The events actually take place 10 years after Bioshock, and Rapture is now under new administration, some deranged woman named Sofia Lamb whose busy creating Big Sisters for her army, a sort of Little Sister/Big Daddy hybrid. Since Rapture is a big place, I'm guessing we'll get to explore a whole new side of it and plus, who knows what happened there in the past 10 years, something I cant wait to find out.
Here is a small video clip of the new gameplay elements, as you take your first step in the Big Daddy's shoes.
