Dead Space and FEAR have their moments. I can recommend both.
There seems to be an abundance of 'pure' survival horror around at the moment, with more on offer soon.
A couple of titles not mentioned already would have to be
Siren: Blood Curse
Japanese horror, film crew happen to film rural community involved in a shared blood ritual, you can fight in some sections, but you ultimately have to run & hide. You can also (in a limited sense) see the world from point of view of the creatures attacking you. Freaky stuff.
Vampire The Masquerade: Bloodlines
1st/3rd person RPG, based on the tabletop RPG. Pretty dark themes throughout as you would expect. Amazing scope for a game of this era, somewhat flawed by bugs on release, but brilliant in it's ambition.
The Hollowbrook Hotel section is particularly worthy of note. It is necessary to enter the hotel to continue the the narrative of the game. I am a huge horror fan, books, films and games. I only managed to complete Hollowbrook in the middle of the day, with bright sunshine outside.
But I will not do it again.
(I'd rather have a fight with the entire cast of demons from The Grudge, armed only with a bit of wood)
