Halo: The Master Chief Collection has been updated with the Halo 4 playlist.
Matchmaking for Halo: The Master Chief Collection now includes the Halo 4 playlist. A Team Hardcore playlist has also been added, with support for only Halo 2 Classic at the moment.
The developer is also working on other playlists to be added later. Playlists like Team Snipers, Team Doubles and an objective-only playlist are all planned.
This weekend, a new patch will be released and will come with UI improvements, matchmaking, and game-specific multiplayer items. The full notes will be revealed once the patch has cleared certification.
