Somebody on another forum mentioned that they played Doom 3 in a dark room with their headphones on, this got me thinking. Because I have to play with the sound down at home, I dug up some old headphones of mine and plugged them and played some Doom... ! Man, did I jump out of my skin!!! Now that I could hear all the little sounds and things, the game gets a hell of a lot more creepier... And I'm still @ Alpha Labs, apparently it gets much more scarier.
