"Rapture is a very different place than it was a decade ago. BioShock protagonist Jack's escape (or demise) left the underwater city disrupted, and the aftermath shaped the way the genetically mutated denizens adapted to their new, even harsher existence. With a fresh recruitment of Little Sisters to harvest the power-granting Adam also comes a new generation of enemy splicers -- some faster, and some stronger, like the heavyset "brute." But the girls also have a bigger and badder retinue of protectors, including the Rumbler, a new heavily defensive Big Daddy model, and, of course, the lithe and deadly Big Sister. Throw in some new powers and you've got a recipe for chaos."
