Downloaded the FEAR demo to give my new 8800GTS a run for it's money...I'd played it before on my AGP card, and didn't think the atmosphere could be much improved on with a couple of graphical tweaks, but after slamming everything up to maximum at 1600x1200, I must admit I crapped my pants.
Arm hairs standing on end, shivers down my spine, and hesitating before every corner. FANTASTIC!!!
Plus great AI, cool weapons, great slow mo (the close up kills with the shotgun leaving nothing but bloody mist hanging in the air are just stunning....in a really sick kind of way ), and the best atmosphere I've seen in a long time.
Going to pick up FEAR Gold tomorrow if I get the chance....awesome game.
