Quote from Garret
Not really, it was a FPS with a few scary moments interspersed between the action. You could argue it was survival horror for the first couple levels but (At least the Japanese definition of the term) it needs to be more slow-paced and limited in power. Unlike in Doom were you've got the BF(ucking)G!
Are you sure you're not thinking of another game? DOOM 3 was uniformly creepy throughout, the only part that didn't involve being shocked by a demon jumping out of the wall and slaughtering you while you desperately grab your shotgun was the first 5 minutes.
