Halo: The Master Chief Collection might not have gotten off to the best start at launch in November 2014. But it has rebounded well since then, thanks in part to Microsoft's commitment to improving the game with regular updates, and its player population remains good enough to find matches easily. Microsoft's updates for Halo: MCC continue with one of its biggest yet later this year that makes significant changes and improvements. In addition to that, Microsoft is updating the game to add enhancements for people playing on Xbox One X.

Halo community manager Brian Jarrard spoke about this update recently. He said on the latest Inside Xbox episode that the work-in-progress version that the studio is testing now looks "gorgeous and stunning." He added, "The first thing Xbox One X owners will notice is the visual enhancements. Now with Xbox One X, we have a full visual enhancement suite, including HDR support."
