It's been more than a week since Halo: The Master Chief Collection hit shelves, and players are still waiting for matchmaking issues to sort themselves out. Right now, lots of players still can't regularly get into multiplayer games. It was supposed to get better with a patch tomorrow, but it's been delayed.
A recent update says the patch "will now be releasing later this week to allow for additional fixes, as well as the completion of the testing and certification process."
That does sound important, yes, but it doesn't make The Master Chief Collection's issues any less glaring or frustrating.
Full patch notes are coming later this week, but promised changes include:
"This content update includes a variety of fixes across the title, including Matchmaking performance issues, general UI and game stability improvements, as well as fixes for game-game specific issues in Halo: CE, Halo 2, and Halo 2: Anniversary, and more. The full patch notes will be posted later this week, in advance of the content update release."
