The Free Fire OB52 Advance Server is now opening registrations for the highly anticipated January 2026 update. Players around the world are excited to play upcoming leaked “Morse” stealth character and experience the confirmed Jujutsu Kaisen collaboration, before they are released on the main servers.
This complete guide will help you understand everything you need to know about the OB52 Advance Server.
What is the Free Fire OB52 Advance Server?
The Free Fire OB52 Advance Server is not the actual game, but an experimental version. All the new features, characters, modes, and balance changes are added here first, which will later be rolled out in the main OB52 update coming in January 2026.
Garena opens this Advance Server for selected players approximately every two months, so they can test the game in advance, catch bugs, and provide feedback. In return, players often receive rewards of up to 1000–3000 diamonds.
- Registration Opens: December 26, 2025 (Expected)
- Server Active Period: 7-10 days
- Global Update Release: Mid-January 2026
The server typically closes approximately 8 days before the main patch goes live.
