I've heard a lot of good things about the game and I heavily enjoy DOOM 3, which from what I've seen is quite similar, a horror FPS where you get to shoot at what scares you, and I also enjoyed Trepang2, which is supposed to be a spiritual successor to the game. If I should, where should I start? I don't know if I can get my hands on the first 2, but I know that F.E.A.R 3 is on Xbox and I'm quite interested in playing it.
