Aftershock can't touch NIN's guitar sounds, the one in track001 (track 2 on the Quake CD because of the data track) seems to have been substituted by a synthesizer? It doesn't have the same punch.
Track 03: I miss the voices (Shub-Nigguraaaath!). I listen to that track a lot atm because it's in the map I'm working on

Good attempt, but I prefer NIN. I don't know why this was made, probably for fun, which is cool. Hats off to the producers.
