After twelve years of development, DESOLUS finally gets a release date. The first-person puzzle game from solo developer Mark J. Mayers, published by The Quantum Astrophysicists Guild, is set to launch on October 15, 2026 for Xbox Series X|S, PlayStation 5, Nintendo Switch 2, and PC via Xbox and Steam. Mayers is no stranger to ambitious projects, having contributed to the BAFTA-winning Outer Wilds and the critically acclaimed Manifold Garden. Expectations for his first solo album are therefore understandably high.
Set in a sprawling gothic city on the brink of annihilation, DESOLUS tasks players with preventing an apocalypse by traveling between two timelines: the city’s past and its catastrophic future. The central mechanic involves manipulating black holes to solve architectural puzzles, moving stairs, archways, and debris between timelines to make your way deeper into the city. The visual inspiration is clear from the start, with the game drawing heavily on the loopy, impossible architecture of MC Escher, applied here to a world of towering cathedrals and ornate Gothic structures.
The city itself is divided into seven distinct zones, each requiring keen spatial reasoning skills as players strive to rebuild the architecture over time, unlock light-powered gates, and push further towards the city’s central castle. Along the way, there is an enigmatic guardian to seek out, whose knowledge may prove key to uncovering the source of the temporal disaster threatening Desolus. Mayers described the project as something he spent over a decade developing, building an entire city of Gothic architecture for players to explore.
“DESOLUS has been my life’s purpose for twelve years. I have put my heart and soul into it,” Mayers said in the press release. “I’m excited for players to experience this world I’ve created, filled with stunning architectural puzzles and stunning landscapes.” For a title that was solo-developed and over a decade in the making, this level of dedication is reflected in the scale of what’s presented, from the elaborate puzzle design to the atmospheric world-building at its heart.
DESOLUS will launch on October 15, 2026 with an impressive list of supported languages, including English, French, German, Japanese, Korean, Spanish, Portuguese, Chinese (Simplified and Traditional), and many more. For more information, the official DESOLUS site is worth a visit, and solo developer Mark J. Mayers can be followed on X and Bluesky for updates leading up to launch.
