Majjam is the first game from the recently-announced studio Opus Major, and it’s an exciting multiplayer adventure game that relies entirely on music to power its gameplay. From the way you traverse the world and engage in combat through to how you interact and explore, Majjam is inspired by “live jam” sessions–where musicians bring their instruments and voices to an improvised musical collaboration.

Majjam is described as a co-op multiplayer adventure and MMO, where you can use your own rhythms, melodies, and harmonies to work together to rescue the world around you. Music, as the world’s life force, is the only thing holding back the corruptive element known as Kodé. Kodé is a dark presence that’s encouraging death and silence via an ominous fog.

Working together, you and your friends will harness musical energy via jams, using your characters’ unique abilities and instruments to solve puzzles, defeat enemies, and ultimately rescue the world.

While Majjam relies on music and creativity to progress through the game, Opus says that there is “no instrumental expertise” required to play. You’ll unlock more musical abilities as you progress, and each one has a specific power that will unlock the world’s true potential.

Speaking about the announcement, Opus Major founders Pierre-Armand Nicq and Jean-Nicolas Vernin said, “Our team’s dream is to make the world jam together. In music, a jam is a suspended moment–a shared energy between friends, strangers, and other passionate souls who just happen to be there. You might not know each other, but for a few magical, spontaneous moments, you vibe together. It’s that same spark you sometimes feel in a multiplayer game. Our dream is to bring all these joyful moments together into one single, shared experience.”

Majjam is launching a closed alpha playtest this September. Opus says it knows the first version of the game will be “flawed” but that it values player feedback. “We’re inviting players not just to test the game, but to help us build it in the next months,” it said. To join the closed alpha test, you can sign up on the Majjam website. It’s also available to wishlist on Steam.
