You can go ahead and download a demo for it on steam:
Humble Store Demo is also steam:
Or you can get a DRM free demo on GOG:
I'm pretty excited about this. It has alot of the people who made the original game working on it. It also looks they have a good representation of the game being made. I have backed this myself.
The original System Shock hasn't held up as the sequel, the controls were wonky but the story was pretty good.
What do you think about the reboot/remake? Are you going to join the kickstarter or wait till it's released?
I'm going to give the demo a spin when I get home from work.
