Bioshock 2

Set approximately 10 years after the events of the original Bioshock, the halls of Rapture once again echo with sins of the past. Along the Atlantic coastline, a monster has been snatching little girls and bringing them back to the undersea city of Rapture. You are the very first Big Daddy as you travel through the decrepit and beautiful fallen city, chasing an unseen foe in search of answers and your own survival.
