It does look nice, but I had serious issues with the frame rate. I was barely getting 5 FPS (if that, at all... was probably closer to 2 or 3) while playing and the slightest movement of the mouse and keyboard was enough to send my aim hurling towards the other side of the room, making it impossible to aim my weapon at the bad guys.

Oh, I ran into something else. I played this on another setup of mine and found that while the frame rate was fine, the game had the 'up' button stuck in some way that I was always moving forward no matter what happened. I tried everything I could think of and it would not become unstuck. I did manage to win, despite that, at least.
