God, that 'thud thud' sent shivers down my spine even on a wimpy little Stereo soundblaster! LOL
Indeed, a quite possible situation in DOOM 3:
You are walking down a dark hallway (as if there are any other in DOOM 3

) and you hear the "thud-thud" sound of a Cyberdemon, you start wondering where the hell he is, maybe around the next corner or so, and suddenly he comes crashing through the wall right next to you

that would be kind of neat.
