MONOWAVE is out on PC via Steam and Nintendo Switch, with the PS5 and Xbox Series X|S versions still scheduled to follow within 2026. Phoenixx published the game and four of its producers now work on the title.
MONOWAVE is a 2D puzzle action game developed by South Korea's Studio BBB and published by Phoenixx. The two companies confirmed a September 17, 2026 release for PC via Steam and Nintendo Switch, moving the project from an announced date to a shipped title. A free Steam demo covering up to the boss of Stage 1 was available before launch, and a trailer with gameplay footage accompanied the release date announcement.
The game has no combat. Players control Mono, a guardian spirit who switches between four emotions that work as abilities: happiness for a high jump, sadness to shrink and pass narrow paths, anger for wall kicks, and anxiety for cautious movement that avoids traps. Mono's song spreads emotions to companions, who then assist with traits such as melting ice with fire or tossing Mono into the air. Each store carried a 10 percent launch discount.
At Tokyo Game Show 2026, Phoenixx president Kazunori Sakamoto said he first saw the game at Taipei Game Show and pursued it for a year or two. Studio BBB CEO Lim Gwon-yong said four Phoenixx producers now work on the title. The puzzle difficulty was the one point both sides argued over during the publishing deal. The PlayStation 5 and Xbox Series X|S versions remain scheduled for within 2026.
