A few days before the launch of its first playtest, Opus Major unveils a new gameplay trailer for MAJJAM
MAJJAM is getting ready to thrill players during its first playtest!
Paris – September 17, 2025 — Opus Major studio is proud to announce the launch of the first MAJJAM playtest from September 18 to 22, 2025 (registration at majjam.com). To accompany this first playtest, Opus Major is also unveiling the brand-new gameplay trailer for MAJJAM, its cooperative multiplayer game where music is the magic of the world used to fight against darkness.
Several thousand players have already registered on the game's website to join this first playtest. The opening and closing times for this playtest are listed below:
Start: Thursday, September 18 at 12 p.m. CEST
End: Monday, September 22 at 9 a.m. CEST
This first MAJJAM playtest is taking place at a very early stage of development. Although MAJJAM is still far from its final form, Opus Major has decided to launch it in order to gather player feedback as early as possible and incorporate their expectations from the very first stages of the game's development.
Players can still sign up for the playtest in the coming days, add the game to their Steam wishlist, or join the Discord community.
Watch the new gameplay trailer below:
A world in danger, an unexpected weapon: music
In MAJJAM, an evil force is slowly spreading its deadly and silent grip. To protect their world and save their lands, players must unite and face the dangers threatening the universe.
Their only weapon: music.
MAJJAM is not a rhythm game and requires no musical skill. The heroes express their magical powers through melodies and rhythms, harmonized by online technology developed by Opus Major, offering a fluid experience with no apparent latency.
Each time the heroes play music, face the dangers of the world, or explore its secrets, the universe of MAJJAM fills with energy to repel the darkness that threatens it in regular waves.
Key features
Save the world with the power of music
The joy of jamming, accessible to all—no musical skills required
A world rich in wonders to explore
A system of “Jam Cards”—unlock, collect, and store musical abilities to enhance your powers and interact with the environment
A unique cooperative experience where each player contributes to the collective symphony

About Opus Major
Founded in January 2023, the Opus Major studio has a strong artistic ambition. The studio's name reflects this vision: “Opus” evokes the work and artistic ambition of the teams, while “Major” conveys the scope of a project designed to resonate far beyond gaming, on several platforms and in a rich universe yet to be developed.
Having raised 10 million euros just one year after its formation, the studio unveils MAJJAM, its first project, in which the team aims to unite two powerful vectors of emotion: music and video games. The idea is simple but ambitious: to create a world where music becomes magic, encouraging cooperation.
