F.E.A.R. 3 or Silent Hill 3 or Silent Hill 4 or Doom 4?

I'm not sure if Silent Hills/Doom will scare you, but I will tell you that F.3.A.R. is NOT a scary game. It's quite fun but it's not a "horror game" per se. Neither is Dead Space 1 and 2, since they're more action oriented. DS and SH do have great atmosphere though. The soundscape of Dead Space is frightening at times. And one thing for sure: Amnesia will make you sh** your pants.
