System Shock 2 is the sequel to the award-winning original System Shock. It is 35 years after the destruction by an unnamed hacker of the TriOptimum-owned Citadel Station and Shodan, the rogue AI controlling it. TriOptimum scientists develop the theory for a faster-than-light starship drive, but the UNN is unwilling to allow TriOptimum sole access to the rest of the universe. Later, a compromise is reached: a TriOptimum corporate starship, the Von Braun, is constructed, but on its maiden voyage it will be accompanied by a UNN heavy destroyer, the Rickenbacker, in case of any hostile alien encounters. The Rickenbacker is crewed by UNN Navy, Marines, and the OSA--experts in psionics.
Your character is one of the Rickenbacker's soldiers and, after training, the game starts as you find yourself waking from cold sleep aboard the Von Braun with no memory of the past weeks. An electronic message from Dr. Janice Polito has just arrived, telling you to come find her on Deck Four, but as you start your journey toward her, all you encounter are scenes of carnage and chaos; the logs of the crew members that you find do not yet explain what has caused things to go so very wrong...
In the demo, you will start with a smattering of weapon skills, tech skills, and cybernetics. You can grow your character any way that you see fit by advancing your skill in the categories that you choose. The full version allows you to build your character in the 3D RPG character generation system. You can choose from three different branches of military service.
