F.E.A.R. for me.
I didn't finish it, had to uninstall because I needed disk space on this laptop
(didn't play very smooth anyways haha)
The scariest part to me was one point when you're walking on the catwalks, then at one point you go down a ladder, and when you go down ladders in F.E.A.R. you actually look at the ladder than turn around and go down normally (unlike CS, where you just kind of glide down backwards lol), and you walk up to it (no one is there) then when you get on the ladder and turn around the girl is suddenly there, so naturally I got scared as crap then rushed down the ladder to run away then as soon as you get to the bottom and turn around the GUY is there and he lunges at you and screams then dissolves in the air... >_<
That freaked me out for a good few minutes. lmao
