If it plays anything like System Shock 2, it'll be far from simple minded. Here's a video of System Shock 2...but remember that this was released in 1999, so don't expect the graphics to be as good as something like Doom3. They're pretty damn good for the time, which added with the music helped to emerse you in the atmosphere. The game is set on a computer-controlled spaceship that decides to rebel....think Event Horizon meets Matrix.

I know that this isn't Bioshock, but it's what was the base foundation of what Bioshock is all about. So if you like Bioshock, you should be interesed in System Shock 2....or vice versa.
