Armored Core VI: Fires of Rubicon (2023) marked FromSoftware’s return to its mech franchise, and its soundtrack matches the high-speed combat with a bold, synth-driven score from the studio’s in-house sound team, led by returning composer Kota Hoshino.
Set on the remote planet Rubicon 3, the game’s music leans on analog synthesizers for a deliberately classic sci-fi feel — a distinct sound from FromSoftware’s orchestral Souls and Elden Ring scores.

The Score & Composers
Kota Hoshino, a longtime Armored Core composer, returned to lead the music, joined by Shoi Miyazawa, Takashi Onodera and others on the FromSoftware Sound Team. The result is credited collectively to the studio’s sound team.
The original soundtrack runs 47 tracks across roughly two hours. As the game’s director Masaru Yamamura noted during development, the score makes heavy use of analog synthesizers to evoke a vintage, mechanical, sci-fi atmosphere that suits the planet Rubicon 3 and its towering mechs.
The full OST is available on major streaming platforms, and the music was later celebrated with a “Re:Resonance” live recording.
The release was a major moment for the franchise: Fires of Rubicon is the first mainline Armored Core game since 2013’s Armored Core: Verdict Day, so its score had to reintroduce the series’ identity to a new audience while honoring its mechanical, electronic roots.
