Halo Master Chief Collection Update Highlights

Master Chief Collection update

Xbox Narration Improvements

As stated above, this new update to the MCC is for both the Xbox One and PC. There is just the one Xbox One exclusive patch note to tell you about, however. Following the December 18 update, the game’s front-end narration interface has been improved on Halo: Reach. The game should now be a little more accessible.

Mouse and Keyboard Improvements

Supposedly, there was a legacy mechanic still at play in The Master Chief Collection while playing with mouse and keyboard. This produced some negative effects while aiming whilst taking damage. Following the update, this should now be better to some extent.

General Fixes & Playlist Updates

A few small fixes have taken place thanks to the update, too. The sound effect upon gaining a Season Tier should now play as was intended, for example. That annoying stat error in which multiplayer kills were showing up as deaths too in Halo: Reach has been fixed as well.

A good number of Playlist changes have taken place with the December 18 update, also. In Social 4v4, for example, Oddball has been removed from Solitary. In Reach Hardcore Playlists, you should now notice that the maps and game types no longer have equal weighting. Zealot and Sanctuary, for example, should now show up a lot more as Capture the Flag in Hardcore. Read through the full list of patch notes below to learn more about the fixes and changes.

Improvements to narration across the front-end interface for Xbox.

  • One of our top priorities is ensuring that Halo: Reach is accessible to as many players as possible. Today’s patch includes a few updates to further improve accessibility for the title.

Addressed a mechanic for mouse + keyboard players which improves precision of aiming when taking damage.

  • As part of our ongoing work to assess player feedback across controller and M+KB inputs, the team discovered a legacy mechanic from the original game that was contributing to negative sentiment regarding the feel and responsiveness of playing on M+KB. We have adjusted this mechanic and are interested in what the community thinks of this change. The team will continue to monitor player feedback around controller/M+KB input.

Additional small fixes:

  • Fixed an issue which prevented the sound effect for unlocking a season tier from playing.
  • A stat error has been fixed that was causing multiplayer kills in Halo: Reach to increase the deaths in your service record.
  • A new Halo: Reach themed splash screen has been added to celebrate the inclusion of Reach, our sixth title into Halo: The Master Chief Collection.
  • Resolved an issue that could cause players to be kicked from a matchmade game when an intermittent loss of Xbox Live connectivity occurred.
  • Fixed an exploit where season items which were manually made available while Easy anti-cheat (EAC) was disabled and were able to equip them after launching on an EAC enabled exe.
