System Shock is a 1994 first-person action-adventure video game developed by LookingGlass Technologies and published by Origin Systems. It was directed by Doug Church with Warren Spector serving as producer. The game is set aboard a space station in a cyberpunk vision of the year 2072. Assuming the role of a nameless security hacker, the player attempts to hinder the plans of a malevolent artificial intelligence called SHODAN. System Shock's 3D engine, physics simulation and complex gameplay have been cited as both innovative and influential. The developers sought to build on the emergent gameplay and immersive environments of their previous games, Ultima Underworld: The Stygian Abyss and Ultima Underworld II: Labyrinth of Worlds, by streamlining their mechanics into a more "integrated whole".
