The games original score was created by Finishing Move, composers comprised of Brian Trifon, Brian Lee White, Jay Wiltzen, and Alex Klingle, who have delivered a soundtrack worthy of the Slayers legend. The music is a sonic reflection of the games adrenaline-fuelled action, its unique Medieval setting, and the raw energy of the classic DOOM experience.

Elements of thrash metal, modern deathcore, early doom metal and Swedish black metal bleed into brutal guitar breakdowns and downtempo grooves, while traditional folk instruments such as the Nordic bass tagelharpa, balalaika and massive animal hide drums are combined with modern synths for a dark and gritty sound that feels raw, primal and unmistakably DOOM.
