This is the longest MIDI I've made, and probably the best. As a whole it has a dark and hopeless theme. It starts out slow, and builds up until eventually reaching a fast-paced section in the middle that doubles the tempo, before returning to the initial depressing theme and tempo. It's suitable for dark environments where action takes place. Originally made on request for a Doom WAD called Abaddon's Garrison.

No .ogg download because the soundfont has potential copyright issues. I may upload a replacement later. If you would like to record it yourself, I recommend the Arachno Soundfont or EmperorGrieferus's SC-55 soundfont.
