DECEMBER 15 HOTFIX
The following issues were resolved by the December 15 Hotfix.
Global
- Improvements to online service connections after re-entering Halo Infinite using Quick Resume on Xbox Series X|S consoles. Players should see quicker and more stable reconnections to our services.
Campaign
- MJOLNIR Armor Locker customizations collected in Campaign are now consistently unlocked in the Multiplayer Customization menu.
- Players who did not receive their customizations, either due to losing their internet connection or using Quick Resume on Xbox Series X|S consoles, should now have their customizations unlocked.
- Xbox Achievement reliability has been improved in this update.
- Achievements no longer track progress toward their completion, but will unlock as expected when their conditions are met.
- If an Achievement’s conditions were met prior to this update but the Achievement did not unlock as completed yet, it should unlock after installing this update and continuing Campaign gameplay.
