Thank you for being with us from the very beginning!
The O2Jam team has prepared a special gift as a token of our gratitude.
We’ve sent this gift to a carefully selected group of Early Access O2Jammers who have shown O2Jam so much love and support.
Selected players can log in to the game to receive one Steam Key Invitation, allowing them to give O2Jam : The Beginning to a dear friend.
Share it with a friend you’d love to enjoy O2Jam’s music with, and have fun playing PVP and DJ modes together!
When to Check for Your Invitation
After the update on Friday, October 16, 2026 – Saturday, October 31, 2026, at 23:59 (KST)
How to Check for Your Invitation
If you’ve been selected, an invitation pop-up will appear when you launch the game, displaying one Steam key for the base game.
Copy the key from the invitation pop-up and send it to the friend you’d like to give it to.
Even after closing the pop-up, you can view your key again by clicking the “Steam Key Invitation” button in the lobby, as long as the activation deadline has not passed.
How to Activate a Steam Key You’ve Received
In the Steam desktop client, select “Games” → “Activate a Product on Steam” from the top menu, then enter the key.
The key can be activated on a Steam account that does not already own the base game.
💡 Who Gets an Invitation First
The more time you've spent with O2Jam, the better. Our thanks reach those who have kept Early Access close and enjoyed it for a long time.
Play the songs yourself. Rather than staying in the lobby, the more songs you play, and the more steadily, the better.
Try a variety of songs and modes. The more widely you enjoy PVP and DJ Mode, the deeper your time with O2Jam grows.
Important Notes
Each invitation includes one Steam key.
The key must be activated within 7 days of the exact time it is automatically issued when you log in to the game. Please check the remaining time displayed in the pop-up.
Keys that have already been issued can still be activated until their individual deadlines, even after the event ends.
Unused keys will be revoked after their activation deadlines and, as a rule, will not be reissued.
The key is for the base game only. Separately sold DLC is not included.
Each key can only be activated once. Please send it to your friend in a private message rather than sharing it in a public post or comment.
No key will be issued if the event ends or the available supply runs out before you meet the requirements for receiving one.
Congratulations to all O2Jammers who have been selected to receive an invitation!
Give the gift of O2Jam to a dear friend and discover the joy of playing together.
