Catechesis -カテケシス-

Synthesized from 2 Yomimono stories · updated 1d ago

Baroque Decay's Catechesis was announced in 2013 as the studio's first title, then suspended when the project grew too large. The studio has since revived it and set a PC release for summer 2027. The game follows Daniel, a boy possessed by a demon who fights demons in dungeons at night.

The first public look came in June 2026, when Baroque Decay released a demo covering the first dungeon, main character encounters, and about an hour of play, alongside a new trailer. At that point the release date was undecided. The demo's reception on Steam is the clearest signal of where the project stands: an Overwhelmingly Positive rating, with 99 percent of more than 700 user reviews positive.

By October 2026 the demo had been updated with a baseball minigame, a study minigame, and leaderboards, and the studio had moved from an undecided date to summer 2027 for PC. The throughline is a project that sat dormant for more than a decade, returned as a playable demo, and now has a release window attached.
