Tis' the season, so what are a couple of your favorite horror games?
Dead Space 2 - While not the scariest game, the constant dread you have through it is pretty great, fighting off hordes of necromorphs that can only be killed by hacking off limbs and crushing their corpses with your boot, I mean, they don't pull any punches with that intro at all. I like a game with good atmosphere and I feel this game does everything right.
FEAR - No specific game, though mainly the ones before FEAR 3, these games could get down right spooky for sure. I like that is a violent FPS game, but then your mixing all this visual horror throughout with Alma constantly showing up. It keeps the heart rating moving lol Sadly FEAR 1 has not aged well at all as I'm come to find out, though it's still rather creepy. I might take the time to beat FEAR 3 eventually.
At the moment, I'm drawing a blank on others I'd feel would fit here. I love zombie stuff, but Dead Rising, Dead Island, anything like that isn't scary. I'd also like to put Silent Hill 2 through 4 here, but I never beat those games cause they freaked me out years ago and could barely touch them lol
*EDIT*
Fatal Frame - I knew I was forgetting something! This game scared the crap out of me and my buddies years ago. It has the best mechanic for putting you into the terror by making you stare at the ghosts coming at you. Look into their faces or die! One time my friend had a huge subwoofer under his bed that he didn't realize it's volume was way up and when a ghost showed up, it rumbled the bed and shook it good, freaking everyone out lol
