If you bought Halo: The Master Chief Collection for the Xbox One earlier today, but have yet to connect to the game's online matchmaking servers, you are not alone. Microsoft has admitted that the matchmaking features in the new first person shooter collection currently have some issues that need to be fixed.
In a post on the Xbox Live service alert page, Microsoft said:
Hi Xbox members, we're seeing longer than expected Matchmaking times for some regions for Halo: The Master Chief Collection. Matching times will improve as we continue to roll out. If you do not find a match after a few minutes, please restart your search."
In addition, playlists that are specific to one of the games in the collection, Halo: Combat Evolved, are currently not available. Have you encounted any problems with matchmaking while playing Halo: The Master Chief Collection?
