Free Fire OB52 Advance Server is expected to release soon, as the official OB52 update is scheduled for January 2026 and will feature a Jujutsu Kaisen collaboration. The FF Advance Server is a special test server that Garena releases before every major update to check new features and gameplay changes. It usually comes out 18–20 days before the main update. To join the FF Advance Server, gamers must register first. After registration, they will receive a Free Fire OB52 Advance Server Activation Code. Once the download becomes available, players can use this code to access the server and test the upcoming update.
Free Fire OB52 Advance Server: Expected Release Date and Website
The Free Fire OB52 Advance Server is expected to be released in the last week of December 2025. Garena usually opens the test server around 15 to 20 days before the main update, and this pattern has remained the same for almost every OB update. Since the OB52 major update is likely to arrive on 15 January 2026, the Advance Server should open between 26 December and 31 December 2025. This timeline matches the usual gap seen during previous updates like OB51, OB50, and OB49.
The Advance Server generally runs for 10 to 14 days, giving players enough time to test new features, report bugs, and share feedback. Keeping this in mind, the OB52 Advance Server may remain open until the first week of January 2026. Players will need an Activation Code to enter, which Garena provides only after registration. Overall, late December 2025 is the most accurate expected window for the OB52 Advance Server.

How to register and get the Free Fire OB52 Advance Server Activation Code
To join the FF Advance Server, players must register on the official Advance Server website. This special server lets gamers test new features before they come to the main game. However, entry is limited, so Garena gives Free Fire Advance Server Activation Codes only to selected players. These codes help control the number of users and ensure the test runs smoothly.
To register, visit the official Advance Server page when the OB52 server goes live. Log in using your Facebook or Google account that is linked to your in-game ID. After logging in, enter your active email address and tap the “Join Now” button. If your registration is approved, Garena will show your Activation Code on the screen. Copy this code and keep it safe. You will need to paste it inside the Advance Server APK to log in. Without this code, you cannot access the test server.
