French studio Opus Major unveils MAJJAM: An adventure where the power of music can save the world!
A cooperative journey where every note can change the fate of the universe.
PARIS, France — July 8, 2025 — The emerging French studio Opus Major, which earlier this year announced a €10 million fundraising round, is now unveiling its very first game: MAJJAM, a unique multiplayer adventure where players must unite to save their universe through the power of music.
MAJJAM immerses players in a dreamlike open world where music becomes a tool for both creation and action. Together, they can jam, explore, and push back the darkness in an experience that's accessible to all.
Dive into the world of MAJJAM with the official trailer:
The world of MAJJAM is in danger. An evil force, Kodé, is slowly extending its deadly, silent grip.
To protect their lands and preserve their world, players must unite and confront the growing threats across the universe.
Their weapon? Music.
MAJJAM is not a rhythm game, and no musical skill is required. As heroes use their powers to explore and defend the world, every interaction generates melodies and rhythms in real time. The game's self-harmonizing technology ensures that players' overall performances are consistent, online and with no noticeable latency.
Every note played is a spark, every harmony rekindled is a beacon in the darkness. Because in this story, music isn't just entertainment : it's the world's lifeblood. A weapon. The light that pushes back the shadows.
Regarding the announcement, Opus Major founders Pierre-Armand Nicq and Jean-Nicolas Vernin shared:
"Our dream as a team is to make the world jam together. In music, a jam is a special moment: you share energy with friends, strangers, and fellow travelers. You may not know each other, but you vibe together in a magical, spontaneous instant. That feeling — It's also what you sometimes feel in a multiplayer gaming experience. Our goal is to bring those joyful moments into a single, united experience."
Key Features of MAJJAM
- Save the world through the power of music
A silent death spreads, slow, heavy, and cold. Kodé's fog devours everything in its path : life, color, even sound itself. Kodé isn't just a villain; its strength shows up as a major environmental threat in the game. An active, deadly force that restricts exploration and tightens the boundaries of the open world.
But players are not powerless: by using their musical powers, they can push back the fog, revive lost areas, expand their territory, and uncover the hidden secrets of MAJJAM's universe.
- The joy of jamming, accessible to all
MAJJAM captures the joy, intuition, and spontaneity of a jam session, without any musical skill needed. Melodies and rhythms come alive in real time, perfectly harmonized with other players. As they jam, the world responds : landscapes shift, lights pulse, and the entire environment dances to the beat.
- Explore a world full of wonder
In MAJJAM, players journey through a vibrant world where music is both a tool and a source of life. Notes played throughout the adventure revive lands, awaken ancient sanctuaries, and uncover secrets buried in silence.
Melodies guide exploration and lead to environmental puzzles, cooperative challenges, and long-lost trials designed to be experienced together.

While not all of MAJJAM's secrets have been revealed just yet, development is progressing smoothly. The studio plans to gradually unveil its universe, with a limited playable alpha version set for release in 2025, giving players a first taste of this musical journey.
