Explore a living world powered by Ecological A.I., where the inhabitants have interesting and consequential relationships with one another that impact your gameplay experience. Genetically modify your body through dozens of Plasmid Stations scattered throughout the city, empowering you with fantastic and often grotesque abilities.

Upgrade your weapons with ionic gels, explosives and toxins to customize them to the enemy and environment. Take control of your world by hacking mechanical devices, commandeering security turrets and crafting unique items critical to your very survival. 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. Constructed as an idealistic society for a hand picked group of scientists, artists and industrialists, the idealism is no more.

After your plane crashes into icy uncharted waters, you discover a rusted bathysphere and descend into Rapture, a city hidden beneath the sea.

Going beyond 'run and gun corridors,' 'monster-closet AIs' and static worlds, BioShock creates a living, unique and unpredictable FPS experience.
