The Free Fire OB51 Advanced Server is expected to arrive in September, with the global update rolling out on October 29, 2025.

Garena Free Fire fans are gearing up for one of the most exciting times of the year, the arrival of the Free Fire OB51 Advanced Server. While players are still enjoying the content from OB50, leaks and rumours about OB51 are already dominating the community.
What is the Free Fire OB51 Advanced Server?
The Advance Server is a special testing space that Garena opens before every major update. It’s a temporary, invitation-only server that allows selected players to get early access to new features, gameplay systems, characters, and event content before they launch worldwide.
Here’s what makes it so important for the Free Fire community:
- Players get to try out new characters and gameplay modes ahead of everyone else.
- Early testers uncover bugs and help balance gameplay, ensuring a smoother global release.
- Participants often receive rewards like diamonds or skins for actively reporting issues and providing valuable feedback.
For OB51, this means a chance to preview brand-new features, potential Halloween event content, and weapons making their way into the October update.
FF OB51 Advanced Server Release Date Leaks
Although Garena has not officially confirmed the exact launch date, reliable leaks suggest that the OB51 Advanced Server will open in September 2025. Invitations and registrations are expected to drop soon, giving lucky players early access before the global rollout.
This follows Garena’s regular schedule: every major update gets its Advance Server roughly a month before launch. The official OB51 global update is expected on October 29, 2025, perfectly timed with the festive Halloween season, hinting at spooky-themed content.
Registrations and How to Join
Spots for the Advanced Server are limited, so registration is crucial. Official invites and download links for the APK are expected on Free Fire’s social platforms and website soon. Once registered, players will be able to:
- Download the APK for the Advanced Server.
- Test unreleased content not yet available in the main game.
- Report bugs to earn rewards and directly help shape the final patch.
Considering how quickly slots fill up, fans are advised to stay alert for registration announcements.
Global Free Fire OB51 Update Release Date
The global FF OB51 update is set to release on October 29, 2025. This timeline fits Garena’s established two-month cycle between patches, following the FF OB50 update launched in July.
All in all, the Free Fire OB51 Advanced Server will likely open later this September, giving select players a sneak peek at upcoming characters, modes, and rewards. This all builds up to the global OB51 update launching October 29, 2025, which promises to deliver one of Free Fire’s biggest seasonal updates yet.
