Yeah, just recently seen gameplay videos of this in action. Never heard much about it.
However, I love Bioshock, FEAR 2, and Half-Life 2. This seems to have elements of all 3.
Think I'll be getting this. It's great that there are still FPS being made with some substance to them, unlike the slew of 'shallow single player story/online multiplayer focused' ones that keep coming out.
By the way, it's developer Ravensoft - are they the ones that made the brilliant Hexen from years ago?
