After some issues and challenges, 343 Industries has finally fixed the Big Team Battle mode's matchmaking problems after it failed to solve the issue in the last update. The developers tweeted, confirming the improvements to matchmaking in the BTB mode. They ask players to close and relaunch to install the new patch.
Besides the matchmaking issue, the new patch also resolved the following issues:
Local Area Network (LAN) multiplayer is now available. There is a known issue for LAN multiplayer: Match settings changed in the Mode Editor still show as the defaults. The changed settings work as expected once the match begins.
Players with AMD Radeon RX 500 Series GPUs no longer experience crashes because Async Compute in Video Settings is turned on.
Players who have turned off Async Compute because of this can now turn it back on.
If Halo Infinite is launched without an internet connection, players can connect to the internet while on the main menu and play online. This does not resolve all scenarios where the game is launched connected to the internet, later loses internet connection, and is stuck offline until the game is restarted.
When launching in windowed mode on Steam, the window shows correct borders.
To compensate players, the team is giving out five XP boosts and five Challenge Swaps, which can be collected until 16 February.
