There's Silent Hill PT (GZPT) and Simon's Destiny, which is a first-person Castlevania with an, optional, mod to play as Samus. I have only tried the base of these 2 games, though, and the play well in my brief testing. I can't remember where I found the links, it has been months.
What have to found that wouldn't make you, instantly, think DOOM?
