Developer 343 Industries is set to release an update that it says will resolve matchmaking problems in Halo: The Master Chief Collection, as well as make numerous tweaks and improvements to other aspects of the game.

The patch is due to arrive on "mid-late afternoon" Pacific Time on Thursday, which means the update may not arrive in the UK until the early hours of Friday.

Multiplayer connectivity issues have plagued Halo: The Master Chief Collection since its release on November 11. Various bugs within the netcode have effectively locked out many players trying to access the game's online multiplayer modes--a problem which has led 343 Industries to apologise publicly and insist its teams are "working 24/7" to fix the errors.

Xbox boss Phil Spencer has said he's "disappointed" with the network problems.

The new patch addresses "matchmaking performance, UI, gameplay, and title-specific issues", which 343 industries has detailed below.

"We have additional content updates on the way, and work is already underway in an effort to continue to improve your experience with Halo: The Master Chief Collection," the studio wrote on its official site.
