BioShock
BioShock is a shooter unlike any you've ever played, loaded with weapons and tactics never seen. You'll have a complete arsenal at your disposal from simple revolvers to grenade launchers and chemical throwers, but you'll also be forced to genetically modify your DNA to create an even more deadly weapon: you.

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. Players step into the boots of the most iconic denizen of Rapture, the Big Daddy, as they travel through the decrepit and beautiful fallen city, chasing an unseen foe in search of answers and their own survival.
