“Ascent of the Arkifane” is the piece of music that plays during the climactic showdown in Warhammer 40,000: Boltgun II, written by Mick Gordon for the fight against Vashtorr the Arkifane. It is a driving industrial metal track built from distorted guitars, synth bass, and heavy electronic percussion, and it gives the sequel’s villain a sound of his own.
Quick answer: “Ascent of the Arkifane” is an industrial metal track composed by Mick Gordon for the final boss fight against Vashtorr the Arkifane in Warhammer 40,000: Boltgun II, launching October 14, 2026.
What “Ascent of the Arkifane” sounds like
The track opens on a low, droning ambience before a distorted, demonic voice speaks a single word, “Vashtorr,” about nine seconds in. From there it shifts into heavy territory, with downtuned djent-style guitars, deep synthesized bass, and punchy industrial drums carrying the main body of the piece.
From that point the music moves through several distinct phases rather than holding one groove. High-pitched mechanical screeches push it into a rhythmic breakdown, chugging guitars and sequenced synths drive the middle, and the percussion briefly drops out for an atmospheric electronic passage before building back to a heavy climax. It finally winds down as the rhythms stop and a lingering synth reverb trails off into silence.
Auroch Digital shaped the composition to evoke “dread and danger,” establishing Vashtorr’s sound as the rest of the game’s score gradually moves toward it.
Why the theme fits Vashtorr the Arkifane
Few Warhammer 40,000 villains stand apart like Vashtorr. Rather than serve one of the four established Chaos Gods, he is a technology-and-invention demigod, spawned by mortal ambition for progress pushed into its bleakest form. His resolve keeps the four great Chaos powers from absorbing him, while he pursues godhood for himself.
From the Forge of Souls, he oversees production of daemon weapons and daemon engines, supplying each of the four Chaos factions while swearing loyalty to none. He seeks power and artifacts enough to rise as a fifth Chaos God. His blend of hellish machinery and tainted technology fits a score shaped by industrial sounds.
Mick Gordon’s role on Boltgun II
Mick Gordon joined Boltgun II as a guest composer, writing “Ascent of the Arkifane” specifically for the game’s final boss encounter rather than scoring the whole game. The track debuted in the release date trailer shown during the Future Games Show at Gamescom 2026, and Gordon confirmed the collaboration on social media afterward.
Gordon is best known for the industrial metal scores to DOOM (2016) and DOOM Eternal, and he has also provided music for Wolfenstein: The New Order and Wolfenstein II: The New Colossus. His approach runs progressive metal through analog effects to produce sounds that feel both aggressive and mechanical, which is a natural match for a boomer shooter built in the tradition of those games.
Only this single boss track has been confirmed as Gordon’s work. The rest of the Boltgun II soundtrack is separate.
Where the theme plays in the game
Vashtorr’s last battle is accompanied by this track. The story sends returning Ultramarine Sternguard Veteran Malum Caedo and new Sister of Battle Nyra Veyrath to a remote star system, where they investigate a surge in Chaos activity. They discover that Vashtorr, the Master of the Soul Forges, has set loose a colossal daemonic machine; it wipes out the Imperial fleet dispatched to investigate.
The two champions then race from world to world to purge the corruption and banish the demigod back into the Warp, with the fight against Vashtorr himself serving as the campaign’s loud, definitive finale. Nyra Veyrath is voiced by Alanah Pearce and Malum Caedo by Rahul Kohli.
