Halo: The Master Chief Collection patch detailed, coming later today [Update: is now live]

Update: As of 7 pm ET, the MCC patch is now available and comes in at 1437 MB in size. Thanks, Thomas W., and others!

343 Industries, the developers behind Halo, have published the massive changelog that's coming in today's patch update to The Master Chief Collection.

The game launched last week but has had severe matchmaking issues for the majority of players. A patch was scheduled for yesterday but was delayed until today (11/20). Today's patch should alleviate all issues that resulted in extended matchmaking times and low matchmaking success rates. Plus there's a bunch of fixes for the different campaigns and a few UI tweaks.

Here's your full changelog for today's update going out to Halo: The Master Chief Collection on Xbox One:


  • Addressed a number of issues that resulted in extended matchmaking times and low matchmaking success rates.
  • Made a number of updates to how matchmaking progress is communicated to the player. With this update, you'll see better, more frequent and more informative status updates throughout the matchmaking flow – so "Players Found" for example, will be displayed to let players know where they are in the matchmaking process instead of simply wondering if it's going to connect.
  • The improved matchmaking flow is as follows:
    • Searching
    • Searching for more players
    • Players found
    • Finalizing matchmaking process
    • Connecting session
  • Made an update to ensure that parties stick together when returning from the post-game carnage report
  • Prevented the ability for players "kick" other players from matchmaking games
  • Made an update to ensure that the Roster correctly displays the "searching" UI rather than "My Game Session" while searching for players
  • Removed the possibility to boost ranking through a custom games exploit
  • Made an update to ensure that players cannot get stuck in the matchmaking screen during map voting
  • Made an update to ensure that the "Connecting to your game" message no longer incorrectly displays in the lower right of the screen during gameplay
  • Made an update to the "team creation" phase that allows players to be grouped by team
  • Made an update to prevent players from seeing the "connection failed" dialogue if disconnected during the map voting screen
  • Improved roster / matchmaking lobby stability
  • Made improvements to the accuracy and stability of the "Game Session Details" UI

  • What a nice little patch lol got to love 343
  • 343 :)
  • Idk what you talking about lol
  • Lmaooooo
  • Version 1.0 coming soon!
  • Seems updated
  • Why I never immediately buy a new game. Save money, and fixes ready to download before you start. :3
    Like when I bought a brand new unopened copy of Halo 4 limited edition for 50$.
  • NO, 343 sucks.  They should have never shipped the game if it had all these problems.  
  • A lot of times the problems dont come to light until thousands of people are flooding the servers
  • Please tell me a game that doesn't have bugs and glitches on launch?
  • Still ... those were quite fundamental...
  • Great news!
  • How do patches work, as far as download and installation? It seems that sometimes a game or app updates automatically in the background, without asking me (I think this is what the little corner banner of an asterisk or gamepad on the top right or left corner of the game/app icons in the Games & Apps area indicate), but that sometimes I'll launch a game or app and right away it'll say "this game needs an update". What's with the inconsistency?
  • Good question, that happens with mine too. Not sure why it does that. I suppose some updates can install in the background, but others actually require the game/app to be running to install (this can't be done in the background). Just a thought.
  • It probably works like windows update, where it checks at specific times and you just catch it before it checks for updates.
  • The white triangle with green asterisk in the top right corner means that an update was downloaded since you last launched the game. The controller icon in the top left corner means that you have DLC for that game installed. Posted via the Windows Phone Central App for Android
  • Thanks!
  • That's all great cause I haven't been able to play online yet lol smh
  • I haven't either. Excited as well.
  • meh, seems they didn't fix the issue with achievements not being awarded after getting unlocked. I think I have at least 10 achievements reading "completed 100% unlocking...." and are stuck forever no matter if you re-do the event/steps to unlock it.
  • Not a game issue, Xbox live issue, since they are server side on Xbox one.
  • Wait a sec, I thought Xbox achievements could be popped offline. Since when do you have to be connected to the Internet for an achievement to pop? Has that always been the case?
  • Not always but it is now
  • This has been the case on Xbox One since the beginning. You can unlock achievements while offline but they will not pop out until you are online.
  • Same! I completed halo 1 campaign on legendary but no cheevs popped :(
  • Will there be a patch to improving quality of streaming in the halo channel. Also
  • Grrr. I'm on a connection that's as slow as molasses and it already took me 2 1\2 days to get it installed when I bought it this past weekend. I hope this update doesn't take as long. Already working 2 days on trying to dl\install AC Unity.
  • Anything but Grandé Comms. DSL. :3
  • See all of you online.
  • If you see me online, please don't kill me.
  • Me either. I'll be unarmed.
  • Halo is love. Halo is life
  • Can't stay mad at halo. I just hope the negative effects of this do not cause people to skip out on this game. It's awesome. I'll play tonight or tomorrow night.
  • I bought it the other day and have never played before. Has a few quirks but its awesome. Even got the wife playing. Honestly have more issues with Pinball FX2 than Halo.
  • Honestly, I have waited to purchase the game. This is my typical behavior as I have little faith in major games running without a hitch in the first couple of weeks. Plus, it gives me time to catch up on other games. :)
  • Good they're fixing a lot of stuff. No love for my unlocked but still locked achievements, though. :(
  • Hope they will bring back halo 4 playlists !
  • It will come back. With all the matchmaking problems they decided to cut back on the number of playlists to help people find games a little more quickly. Once the patch is out and things are working correctly/smoothly, then they'll beef up the amount of playlists again.
  • Me too. Halo 4 is the only one that I am good at.
  • Aweomse that so much is getting patched, good work from them. My only thing is that the onl screw-ups I've encountered offline don't seem to be mentioned, like: --Several Achievements show as completed, but won't unlock. --Terminal 7 (I think it is) in Halo 2 won't unlock for me. Instead, when trying to watch it, it would load, then cancel, and it stayed locked in the Halo Channel, meaning I have to re-beat the level, while hoping it works that time. --Last night, an hour into a level, my friend and I (playing co-op online) got split into different instances of the campaign. So, he progressed while I thought he was just screwing around, until we finally figured out we were no longer together in-game.   Hopefully those just weren't mentioned and WERE addressed, as they all are annoying.
  • Is anyone else having issues with the Bandanna Skull not appearing in the menu even though it's unlocked?
  • Yup. Decided to just say "screw it"
  • Disappointed that there is no system link, major fail for all the Lan events!
  • This is a joke right? They replaced system link with a thing called wifi. You can still plug all 4 xboxes into a single router like previous if you want though. There is still 16 person lan lol. In every Halo actually. Just invite all the friends to a game simple as that.
  • Not much use if you have a switch is it.. This WiFi thing. Who on earth organises LAN events across WiFi..? Posted via Windows Phone Central App
  • Tired of the same crap..
  • The update is supposed to drop sometime pacific time in the afternoon right, which should mean evening for me. That's cool. Thankfully the Xbox one updates games all on its own :) I've got a fee meetings tonight, then its finally halo time...
  • Does it? How come sometimes when I start a game it says "This game needs an update", then? Why didn't it update on its own for me?
  • How will we get invited to that mp twitch stream?
  • Hopefully this fixes Co-Op.  I haven't even been able to get someone to join my "roster" yet.
  • I have the same hope...
  • Awesome.
  • Your Xbox one updates in standby mode. That's why the initial 15gb patch was downloaded before release date so you could instantly play at 12:01 am. I like this feature
  • I had a bug in ce campaign where it pushed me off the map. I was able to run around outside the map. :)
  • This article didn't end with a question. Whaaaa
  • With a decent list like this, does anyone think that the game really finished at launch? Or this was like the soft open/ public beta?... Not really a question, just thinking out loud... Happy with the fix
  • Yes, that's why so many people are upset. Sure there's some hiccups with a major release like this, but a huge list of fixes and a whopping file size indicates it wasn't ready. Not to mention there's still a long long list of bugs to be fixed.
  • Downloading now... Keeping my fingers crossed that it actually fixes things.
  • Loving ❤ it .great game from 343 love u Microsoft
  • I love auto install I'm not at home
  • Is there a way to confirm that an app or game on Xbox One updated?
  • I'm not sure I will check soon. If it doesn't update at start should be good. If you go to games folder you can see a funky icon on the corner of a games tile I think that is an update ....
  • Where is the Halo 4 playlist??? :-\
  • Waiting for it too...
  • I'm still waiting much longer to find a match than I figure I should be....
  • Are you sure the patch was installed? Mine hasn't yet.
  • Anyone know if they fixed halo 2 campaign save?
  • Yea its still not working.....
  • Got the patch but my saved game for halo CE put me all the way back to the beginning of the chapter. Still, love the halo. This collection is a lot of fun so far.
  • Freezes on "Downloading Latest Data" for me.
  • I got stuck there too but I quit the game and relaunched it to get around that. Posted via the Windows Phone Central App for Android
  • How long does that process take because I eventually gave up, especially after my controller kept timing out.
  • Not seeing any improvement at all with the patch. Anyone else? Posted via the Windows Phone Central App for Android
  • I'm seeing huge improvements
  • Better results for me but still sometimes it will be stuck "looking" for a game.
  • Matchmaking is still super slow though, and the update kicked me out of halo ce and deleted my checkpoint, gotta love starting two betrayals from the beginning when you just finished it on legendary :'(
  • 343 is ruining Halo
  • Ok, so when I'll be back home I'll try to play online. If it's not working, guys, i swear I'm gonna drop the game and the Xone trought the window. Keep in touch
  • Still working meh ...
  • Even with the update, this matchmaking is slow as balls. Takes waay too long to find a match
  • UK based MCC player here. Matchmaking FINALLY kicked in for me tonight, totally out of the blue. Never received any update (or rather, not prompted or notified I was receiving anything). Played 4-5 back to back games of Big Team. OH... MY... LIFE! Halo is BACK! Sloppy launch, but seriously, WOW.
