Today, our team is proud to open the very first MAJJAM Closed Playtest, from September 18 until September 22, 2025. It's a big step for the studio and a testament to months of craft across design, engineering, audio, art, and community. Thank you to everyone at Opus Major, and our partners, who helped us get here.
What we're shipping into players' hands
MAJJAM is a cooperative multiplayer adventure where music is magic. Players band together to push back a deadly darkness using instruments, jam cards, and music-driven abilities. This is an early build, focused, raw in places, purposefully open to feedback.
Thousands of players have already registered to join the first session, and we're inviting more to help shape what MAJJAM becomes.
- Playtest window: September 18–22, 2025
- Start: Thursday, September 18 at 12:00 PM CEST
- End: Monday, September 22 at 9:00 AM CEST
- Join in: Register for the playtest, Wishlist on Steam, and join the Discord.
A note on how we build
We believe in sharing early, listening closely, and iterating fast. This playtest is designed to validate core loops, stress multiplayer, and gather real-world feedback on gameplay.
Thank you
To our team: your work made this moment possible. To our community: your playtime and feedback will guide the next measures in MAJJAM's composition.
See you in the alpha. Let's make something unforgettable, together.
