Dead Space and Alan Wake are weapon intensive, but excellent games in my opinion of liking the horror genre. Finding games that don't put emphasis on combat isn't really the popular thing to do ... I mean, there's Silent Hill Shattered Memories. There's an indie game based off the engine of Penumbra called PHOBIA - The Fear of the Darkness (http://forum.thegamecreators.com/?m=forum_view&t=166807&b=35) if you want to give that try. It's short and a little ... different, but interesting to play.
