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. Injectable plasmids give you super human powers: blast electrical currents into water to electrocute multiple enemies, or freeze them solid and obliterate them with the swing of a wrench. No encounter ever plays out the same, and no two gamers will play the game the same way.
Explore the undersea city of Rapture, a haven for society's greatest minds that has devolved into a dystopian nightmare wrought by one man's hubris. Amidst the waterlogged ruins, a new ecosystem has emerged, where deranged Splicers hunt down the Little Sisters who would be helpless without their hulking Big Daddy guardians. Your only hopes for survival are quick thinking, reclaimed weaponry, and superhuman powers granted by DNA-altering Plasmids. To defeat Rapture's mutated monsters, you must become one.
