I love these kind of games. Can't play them myself though cause I'm a big bitch. None the less, this looks really interesting. Nightmare House is a Survival Horror game using the Source Engine and it requires Half Life 2: Episode 2 to run. For those who play it, share your experience. If you can, record it, it'd be fun hearing you scream. :D Their are two parts to it, whether you play both or just the one is up to you. The trailer is for Nightmare House 2.
