Thief 3. Not horror-esque for the most part, but more of a psychological scariness and atmosphere that pervades the whole game.. sneaking in the shadows, holding your breath as a guard passes a few inches from your face.. etc. Definitely a game to play in the dark!
P.S. There was also that one level where it feels like the game devs were like: how can we make this level especially scary? Make it an orphanage? Or an asylum? Ah, screw it, make it BOTH and add zombies!
