After your plane crashes into icy uncharted waters, you discover a rusted bathysphere and descend into Rapture, a city hidden beneath the sea. Constructed as an idealistic society for a hand picked group of scientists, artists and industrialists, the idealism is no more. Now the city is littered with corpses, wildly powerful guardians roam the corridors as little girls loot the dead, and genetically mutated citizens ambush you at every turn. BioShock forces you to question the lengths to which you will go and how much of your humanity you will sacrifice...to save your own life.

BioShock is the "genetically enhanced" first person shooter that lets players do things never before possible in the genre – turn everything into a weapon, biologically modify your body with plasmids, hack devices and systems, upgrade weapons and craft new ammo variants, and experiment with different battle techniques.

Gamers enter the game as a cast-away in Rapture, an underwater Utopia torn apart by civil war. Caught between powerful forces and hunted down by genetically modified “splicers” and deadly security systems, players have to come to grips with a deadly, mysterious world filled with powerful technology and fascinating characters. No encounter ever plays out the same and no two gamers will play BioShock the same way.
