Deus Ex: Mankind Divided Composer Unveils Never-Before-Released Demo Tracks

Fans of the Deus Ex series now have a rare opportunity to explore previously unheard audio creations, as Sascha Dikiciyan, also known by his alias Sonic Mayhem, has released a collection of demo tracks from Mankind Divided entirely for free. These unreleased pieces, which span cinematic cues, trailer themes, in-game club music, and rough drafts, were originally composed between 2015 and 2016 but never appeared on the official soundtrack, offering a fresh glimpse into the game’s creative process.

Described by Dikiciyan as “unmixed, unmastered, and even unfinished,” these raw audio files grant fans access to his original production vault, complete with working filenames and unpolished textures. Though imperfect, the tracks have garnered attention for their rich synthesis of dystopian ambiance and sharp, futuristic electronic elements. In exchange, Dikiciyan invites listeners to explore his other work, notably the soundtrack of the upcoming cyberpunk shooter Metal Eden, signaling both artistic continuity and future potential.

Best known for creating iconic soundscapes in games such as Quake II, Borderlands 2, Mass Effect 3, and the original Unreal Tournament, Dikiciyan has consistently imbued his compositions with an industrial-driven intensity and rhythmic precision. For Mankind Divided, he infused the score with his “future synth” aesthetic, melding atmospheric electronic textures with live percussion and neo-industrial tones to evoke the oppressive and complex tone of the cybernetic world. His contributions complement those of Michael McCann, who returned from Human Revolution, creating a multi-layered auditory identity for the game.

The full soundtrack for Mankind Divided was released in December 2016 in both standard and extended editions. Even years later, Dikiciyan’s decision to share these disused compositions not only enriches the game’s musical legacy but demonstrates notable transparency into its creative evolution. For fans of game music, these tracks provide an immersive window into both the composer’s creative journey and the atmospheric heart of one of the most visually and tonally ambitious entries in the Deus Ex franchise.
