MoonHack is scheduled for a 2027 PC release via Steam from ASTRA, Astro Production's indie brand. The playable rhythm action portion has been hands-on at Tokyo Game Dungeon 13 and at the Tokyo Game Show 2026 indie corner in Hall 9, booth 09-C53.
MoonHack went from announcement to show-floor demo in about two months. Astro Production announced the title on July 7, 2026, as the first game from its new indie brand ASTRA. It is a rhythm action ADV set in 2125, a society where AI manages emotion, love, and creativity. The player follows Tsukuyomi Kaguya, an old-model AI girl branded a criminal, and other characters rebelling by rewriting the world through song. The Steam release is set for 2027, with character design by Noyu, music by Ukiyone, scenario by Shin Kedo-in, and Ariyo Hanami voicing Kaguya. A teaser video carried the song "DANCE ALL NIGHT."
The title had been teased as "Humanity Optimization Plan Eden Protocol - Order of 2125" before an in-universe hack of the official X account produced the MoonHack name. Game Spark played a build at Tokyo Game Dungeon 13 on August 8, 2026, and reported that both the 3D rhythm action and the novel sections were playable.
ASTRA then took MoonHack to Tokyo Game Show 2026 at Makuhari Messe, starting Thursday, September 17, with the booth in the Indie Game Corner of Exhibition Hall 9. Visitors could play a polished rhythm action section, watch the third music video ahead of its September 27 YouTube release, and get a random trading card from 13 types or an original sticker for showing a Steam wishlist screen. By the show itself, the demo covered the rhythm action portion rather than the novel portion, with the booth at 09-C53. The 2027 Steam release remains the only dated window across the four stories.
