The soundtrack consists of 27 new songs, and six songs which previously appeared elsewhere. The new songs were mainly composed by James Paddock and Jamie Robertson, with additional contributions by Julian Aubourg, Eric Baker, Paul Corfiatis and Stuart Rynn. The reused music consists mainly of Doom and Doom II music which had also been reused in The Plutonia Experiment, but includes one Doom track which was not used in Plutonia, as well as the Bobby Prince song "Gut Wrencher" from Duke Nukem 3D.
