You might have heard of the BioShock series, with its amazing dystopian settings and twisted narratives about morality and excess. But you might not know that BioShock rose from another game: System Shock 2, a classic shooter that’s finally getting a new sequel.

System Shock 3 is officially in development from Boston studio OtherSide Entertainment, although the title is currently in early concept phases. Even still this is a big deal, as System Shock 2 is regarded as one of the best PC games ever made.

Set on a derelict spacecraft in which the crew has been turned into violent alien monsters and robots have gone crazy, 1999’s System Shock 2 let players augment themselves with cybernetics, allowing them to shoot guns and zap people with telekinetic powers. It was designed by Irrational Games founder Ken Levine, who would go on to create the much more ambitious spiritual successor, BioShock, which also has guns and special powers and people who go crazy, but is not set on a spaceship.

Sounds like System Shock 3 will also include series antagonist SHODAN, a murderous artificial intelligence that manipulates the player all the way through System Shock 2 (another idea that was lifted almost wholesale for BioShock). You can get a taste of SHODAN’s abusive personality on the System Shock 3 teaser site, where she’s apparently been lightly berating the Shock fans who cracked the code on OtherSide’s big reveal a little early. While you’re there, you can also check out a survey from the developers to chime in on what platforms System Shock 3 should land on and whether you want it to include virtual reality support.
