System Shock 2 begins with you being unfrozen from a long cryogenic sleep aboard the Rickenbacker, a security spaceship assigned to tail the Von Braun on her maiden voyage. Apparently, the Von Braun has been infested by an unknown alien race and has converted the crew into relatively intelligent zombies. You must gather bits of audio clips along the way to figure out what happened to your crew and, more importantly, how you can rid the ship of the aliens. Rely on your skills training from either the Navy, Marines, or OSA to guide you on this difficult path. This 3D title offers unbelievable graphics, as the Thief engine is utilized to provide mouth-watering environments and character skins. The astounding graphics, varied RPG elements, and fluid action make this title worthwhile.
It has a nice, creepy atmosphere- but not many scary moments, and a nice RPG system; the story is well paced, and voice acting is pretty good for the time it was released.
But it's not perfect as some say: from a technical point, the game is average compared to it's contemporary engines (e.g. Half-Life or Unreal).
Monsters and people look too square-shaped, and while they may scare you with their sounds, their look washes away the fear. Sound is also average, some sounds (like the pistol) don't feel right. Gameplay wise, the game forces you, no matter which class you pick, to invest the in 'HACK' skill, because most ammo and health goodies -scarce and needed items- are inside locked crates which need to be hacked in order to be opened. Most PSI powers (magic-like) aren't really useful e.g. Why should I try to be invisible when I can destroy that security camera with a single attack?
Summary: it's creepy, it has one of the best villains (SHODAN), a great story and it's fun overrall, if you don't mind the negative spots mentioned above.
