My first post here. Please don't hurt me. I had problems with the PC controls also. The PC version can be played with a XBox 360 controller.And you have the mouse if you need it (which I personally did on two occasions).
Great game, gets a shade repetitive, but what makes this title is the sound. The bredth of noise - from clanking machinery, the muffled vaccuum areas, the screams and shrieks and yells - that's what really sets the atmosphere.
