Horror games as good as Amnesia?

[xxxxxxxxxxxxxxxx]

Ok so I played through Call of Cthulhu: Dark Corners of the Earth in the meantime. It's riddled with bugs to the point where some missions are only beatable by following very specific instructions in youtube videos (I mean how else do you beat a level that includes hitting three tiny targets with a ship-mounted gun, when half the level - including the targets - is INVISIBLE? ). But let's put that aside, it's not part of the game
First half of the game is a good, creepy and very atmospheric adventure. It takes very long until you even get your first weapon and it captures the spirit of the source material quite well. It's not really fear-inducing though - more slightly creepy. There's some very intense chase scenes, but they suffer from the fact that you have to start them over when you fail and you WILL fail. Quite often. Or at least I did. And when I ran from those crazy Innsmouthians for the tenth time in a row it was a lot less scary than the first time
Unfortunately the second half of the game turns more and more into a shooter. At the end they basically give you the Lovecraft equivalent of the BFG 9000 and by that time there's not much horror left.
Still it's a good game all in all and I'd recommend it. But it's not as extremely scary as I was told. Or maybe that's just because it's pretty old?

Edit: Hold it right there, I almost forgot! There ARE terrifying parts in CoCCotE ! The parts were you turn insane and wander through the hallways of your own twisted mind (or something like that). Those parts were pretty damn horrifying. They were quite rare though.
