The DUSK Soundtrack is composed by Andrew Hulshult, and is composed of various Industrial Metal (with some general heavy metal, and thrash) and Ambient themes. The native format of the songs (and pretty much all of the game's audio files, are .wav files, which can be played in any modern media player made since the 1990s)
