As October nears its end, Free Fire fans are all stoked about the launch of the OB37 version, scheduled to arrive in November. However, before the rollout of the patch update, fans will be able to witness the OB37 Advance Server, which Garena has scheduled to release on November 3, almost two weeks before the final update.
Like previous iterations, fans can expect plenty of additions to Garena's BR games, Free Fire and FF MAX, via the OB37 patch update. Apart from the new additions, the OB37 version will also introduce several optimizations to the game. However, players will be able to see most of the OB37 content via the Advance Server.
Free Fire OB37: The forthcoming Advance Server is expected to launch in the first week of November 2022

As mentioned, the upcoming iteration Advance Server program will be released in the first week of November. The testing phase for the OB37 update will stay online until November 11, and players will get access to the unreleased content after filling in a unique Activation Code.
For the unversed, the Activation Code is 16-characters long, and only a limited number of users will receive it. Therefore, interested gamers must register for the OB37 Advance Server on the official website and get the Activation Code before the program initiates on November 3.
