The developers have stayed true to their word and released another batch of updates for "Halo: The Master Chief Collection." One of the key points in this particular update, which is now live, is the fix for matchmaking issues. It also introduces new improvements and tweaks to the user interface of the game. Moreover, the update gives rise to more stable performance and better multiplayer experience.
