Did you play this?
I loved that game. I was scared out of my wits.
Personally I liked FEAR and Condemned too, but they definitely weren't as traditionally scary as Undying.
It had a lot of great mechanics. Your guy was some kind of psychic sent to help an old friend whose family was in deeeeep, bloody, messy trouble, and the fact that you were a psychic gave you the ability to "scrye", which would be cued by a ghostly voice whispering "Looooooooook...". In a dark room, with no one around, that alone was bad enough, but then when you actually did scrye, you'd be treated to the ghostly happenings beyond the veil.
Paintings coming alive, people coming alive - Just generally creepy shit.
I loved it.
