If you want to skip the process, choose the direct download link for the Free Fire OB51 APK below. Simply download the APK file, install it, and confirm using the code you registered on the Free Fire Advanced Server page above.

Download Free Fire OB51 APK directly

Download the official Free Fire app (awaiting update)

As always, once you've logged in, you'll see the server allowing you to download by displaying the AFK button in green instead of gray. Then you just need to download the Free Fire Advanced Server installer file and install it like any other APK file.

Step 3: The size of the Free Fire OB51 APK file may vary compared to the previous Free Fire OB48 version, depending on the new content included. The version you download will usually be around 1GB. The main content will need to be downloaded within the game later.

Step 4: Create your character's name and select "Let's Go" below.

Step 5: As with previous versions, Garena will still only require players to log in with a Guest account. Since this is a test version, you don't need to use your official Garena account.

Step 6: Next, enter the activation code you received when registering your email to download the Free Fire APK installation file during the registration process. You can register with this code now and save it, waiting until Garena officially allows players to access the server.

Registering for the Free Fire beta will allow you to see what new content is available beforehand. To avoid having too many players on the beta server, Garena has limited the number of players by requiring a code to join.

What is Free Fire Advanced Server?

Free Fire Advanced Server is a test version of Free Fire. In this version, you will have the latest updates, from features and mechanics to maps, characters, and new weapons. You will be able to experience them before they are released to the official servers.

Does the Free Fire Advanced Server have higher system requirements?

The FF Advanced Server is no different from the regular Free Fire version, so unless there are configuration upgrades or graphics enhancement options, the trial version will not require higher specifications.

Is there a limit to the number of players on the test server?

Even before activation codes were required, the number of players on the test server was very limited. Since this server was created solely to test the latest game content, a large player base wasn't necessary.

Is the beta version stable?

The beta version may contain bugs, so players will frequently encounter errors related to image display, feature glitches, game mechanics, etc. While this can be frustrating when experiencing new content, if you find these issues, you can report them to the developers to receive diamonds for your Free Fire account in the official version.

How to report errors in Free Fire Advanced Server

The developers will suggest that you report bugs directly in the game through support tools. Or you can send feedback through official channels such as email, forums, or Free Fire's social media pages if you find any bugs.
