Soooo, Devil Engine...
After some long-running developer/publisher drama that gave way to additional intra-developer drama that I'm not qualified to fully recount, the expansion DLC Devil Engine Ignition was finally released this week. As advertised on the Steam page, this includes new arranged tracks from Shinji Hosoe, Loser Kashiwagi (CHO REN SHA 68K), Hyakutaro Tsukumo (original composer of the track embedded above), and at least one unadvertised remix from cohost's own @heavyviper (see my last rebug, or just click here). None of this music seems to be for sale on its own anywhere yet.
The track embedded here, a fantastic arrangement of "Cosmo Babylon" from Technosoft's Hyper Duel, was part of the initial soundtrack release way back in 2019. That release also included a few tracks from Tsukumo himself, as well as guest tracks from Mason Lieberman and Tristan Chapman. It was pulled from Steam and Bandcamp in 2021 after the dev drama came to a head, but at least composer Joseph Bailey was able to list his original 17 tracks on his personal bandcamp.
