tbh crap game on PC and crap game on xbox 360.
If you have a decent setup on your PC then you wont notice much difference if any between it and the 360 version. I have a 256MB 7800GTX and tbh the 360 version didn't look any better. Maybe slightly smoother frame rate on some cut scenes but other than that.
But the game as a whole just isn't very compelling, just kinda plods along. Although i say this every time i post about fear. The Enemy AI is quite cool. I like it taking cover and turning over tables to get cover etc. But thats about all.
There are better shooters on the 360, and cheaper than this too.
