Opus Major Reveals MAJJAM — A Musical Multiplayer Adventure with a Creative Twist

Opus Major, a studio founded in 2023 by former Ubisoft developers, has officially announced its debut project: MAJJAM. Backed by $10 million in funding, the studio is aiming to redefine musical gaming with a bold, cooperative adventure.

Unite Through Music to Fight Darkness

In MAJJAM, players step into the role of unique heroes and join forces to battle a mysterious, encroaching evil — not with weapons, but through the power of music. The world itself reacts to your melodies, with environments shifting and evolving in response to your sound.

Use your magical instrument to overcome monsters, shape the landscape, and craft original songs in real time. Music isn’t just a tool — it’s your voice, your weapon, and your means of healing a broken world.

Not a Rhythm Game — A Musical Sandbox for Everyone

The developers are clear: MAJJAM is not a rhythm game. Instead, it’s a music-driven experience designed to be accessible to all players, regardless of musical background. At its heart is collaborative creativity, where improvisation, teamwork, and expression take center stage.

Coming Soon — Wishlist and Playtest Now Available

While there’s no official release date yet, MAJJAM is currently planned for PC via Steam. Players can now add it to their wishlist and sign up for a September playtest to get an early taste of this imaginative new world.
