MONOWAVE launched for PC via Steam and Nintendo Switch on September 17, 2026, with PlayStation 5 and Xbox Series X|S versions scheduled to follow within 2026. The game is playable at Tokyo Game Show 2026.
MONOWAVE is out. Phoenixx released the 2D puzzle action game from South Korea's Studio BBB for PC via Steam and Nintendo Switch on September 17, 2026, with a 10 percent launch discount on each store. A PlayStation 5 and Xbox Series X|S release is scheduled to follow within 2026.
The launch confirms the design Phoenixx announced on August 13: players control Mono, a guardian spirit, and switch among four emotions that work as abilities. Happiness gives a high jump, sadness shrinks the body to pass narrow paths, anger enables wall kicks, and anxiety allows cautious movement to avoid traps. Mono's song spreads emotions to companions, who assist with traits such as melting ice with fire or tossing Mono into the air.
Dates held across the two stories. The August announcement set September 17 for Steam and Switch, announced the PS5 and Xbox Series X|S versions for later in 2026, and released a trailer with the trailer announcement. The launch story adds the discount, the Tokyo Game Show 2026 playable showing, and the release itself. The free Steam demo, which the August story said runs up to the boss of Stage 1, is not mentioned in the launch story.
