F.E.A.R.

I know this is an old game, but with the release of the sequel right around the corner, I borrowed this from Maurice to give it a try. Since this game's so old, this will just be a quickie review.

I like it. Solid graphics, good sound, good AI, solid combat. And creepy, to boot. The slow-mo mechanic works, and once properly mastered, you will tear through the enemies like wet tissue paper. My only gripe with combat is that you can only carry 3 weapons, which really doesn't feel like much, and you'll have to manage your load-out carefully. 

If you like first-person shooters, and don't scare easy, grab this game. You'll enjoy it, and it should be a bargain.
