As well as the battle inside Rapture, the game also makes great use of your Big Daddy-issue diving suit, with several sections set outside on the sea floor or inside ruptured sections of the city. These moments, while a break from the action, are eerily tranquil (despite the bodies drifting past you), and offer another angle of Andrew Ryan's creation. The graphics and sound have had an overhaul for this new journey under the sea, showing the grime of the decomposing corpse of the city in all its brutal glory.
