System Shock: Classic

The year is 2072. A hacker from a Saturn colony breaks into computer system of TriOptimum Corporation and gets arrested. He is taken to the Citadel Station, where Edward Diego, a TriOptimum executive, offers to drop all charges against the hacker, as well as grant him a valuable neural implant, if he agrees to hack into SHODAN (Sentient Hyper-Optimized Data Access Network) , the artificial intelligence that controls the station. The hacker removes the AI's ethical constraints and undergoes the promised implant surgery, after which he is put into a six-month healing coma.

System Shock is a first-person shooter with puzzle-solving and light role-playing elements. The gameplay incorporates gradual exploration of the Citadel's ten levels, interaction with the environment, problem-solving, fulfilling objectives, and combat.
