a FPS horror game is a bit tough to pull off and FEAR did about as well as one could hope. The whole idea of an FPS is to mow down as many enemies as possible and get from point A to point B in the most bombastic way allowed. FEAR does this, while, as you stated, working to build an unsettling atmosphere and creating some tense moments. But it is hindered by the fact it is still, at heart, an FPS.
