Halo: The Master Chief Collection Content Updates (2014-2015)

This page lists all Title Updates released by 343 Industries for Halo: The Master Chief Collection.

November Content Update (General)
Released on November 14, 2014, this Content Update focused on campaign, UI, and some Matchmaking and party issues. Performance focused Matchmaking updates were addressed in another content update the following week.

List of Changes

 * Fixed a variety of issues that caused players within the same Matchmaking party to be placed on different teams. In rare cases, this issue may still occur, and we are investigating additional fixes.
 * Fixed a Matchmaking issue with behind the scenes team skill matching, allowing team skill matching to be more accurate in both ranked and unranked playlists.
 * Fixed an issue where the campaign HUD did not reset from level to level with scoring or time HUD enabled. This will clear out the full visualization of level segments, which was previously not reset.
