Free Fire OB52 Advance Server requires a unique activation code that Garena only gives to selected players after they complete registration on the official Advance Server website; without this code, the OB52 client will not open even if the APK is installed. The OB52 Advance Server will run from 25 December 2025 to 9 January 2026, so players must register and secure their code during this limited window.
A special beta client where selected players can test upcoming OB52 features, characters, and balance changes before the global update.
Progress on this test server is separate from the main account and is wiped when the server closes, so it is mainly for feedback and bug testing.
