The Hacker must stop SHODAN from destroying the earth and wipes her completely from the database.

After the six-month coma needed to heal from his surgery, the Hacker finds that SHODAN has gone haywire from having her ethical controls removed, and has transformed the entire crew into cyborgs and mutated monsters devoted entirely to her. ' The Hacker,' caught breaking into the mainframe of the Tri-Optimum Corporation, is offered a chance at freedom and a prime-grade neural interface by CEO Edward Diego, in return for performing nonstandard modifications to the Sentient Hyper-Optimized Data Access Network (SHODAN), the AI on the corporation's space station. A sequel, System Shock 2, was released on August 11, 1999.

It wasn't exactly a smashing success in sales, but it was massively influencial and spawned one of the most memorable villains in all of video games. System Shock by Looking Glass Studios is a groundbreaking First-Person Shooter/ Immersive Sim with Survival Horror and RPG Elements set in a Cyberpunk future.
