Well, I'll throw in Unreal 2: The Awakening....great game.
Sci-fi with horror elements.

Another along the same lines - Star Trek: Elite Force 2...Such a cool game...great storylines, and some fucking hectic battle scenes. More'n a few jumps...

NOES on nes was probably one of the better film-related horror games.

Aliens on arcade was cool, so was Alien 3 on genesis, and Alien: the gun on arcade.

Hmmm...metal Slug 2 had zombies...?

Altered beast, would that count?

Postal 2, and p2: Apocalypse weekend, for SURE. Just about as close as you can get to being a serial killer rampaging lunatic...Gorey as all fuck, and the expansion pack has some awesome zombie stuff.

wouldnt really consider it to be horror related though. more leaning towards comedy. but hot damn, it is an awesome game never the less.

Any suggestions work, thats what the voting is for :)

Duke Nukem: Plutonium Pack had some great horror additions (liek an Aliens style level), plus Duke Nukem's space levels were claustrophobic and pretty godamn scary in their own right.

I guess I must be really out of the video game loop now, because I'd say Donkey Kong, Super Mario, Mario Kart, and Super Ghouls and Ghosts!

Luigi's Mansion

Ghostbusters for the C64 was AMAZING (buying traps and driving around town...)

Carmageddon


When I have time I'll think about it and try to remember, bet I'll think of at least 10/20 more.

"VAE VICTUS!!"

How about a few arcade classics

Joust
Dragon's Lair
Galaga
Ms. Pac Man

The list of Resident Evil games...

The Suffering, The Suffering:Ties That Bind.

Oh yeah, add Pinball of the Dead and Typing of the Dead just to have a pinball game and educational game on the list. :)
