343 Industries boss Bonnie Ross scribed a lengthy apology to the players of Halo: The Master Chief Collection for the game's ongoing issues, and promised to make it right with fans.

Halo: The Master Chief Collection, which bundles together the first four Halo games on Xbox One, was released on November 12 and has been plagued by online matchmaking issues ever since.

"With the initial release of Halo: The Master Chief Collection ... we have not delivered the experience you deserve," said Ross. "I personally apologise for this on behalf of us all at 343 Industries. Our team is committed to working around the clock until these issues are resolved."

"Our primary and continued focus is first on fixing the issues at hand. Once we’ve done that, we will detail how we will make this right with our fans."

Ross said that the online matchmaking issues players were experiencing were not apparent in the internal testing environment prior to release. Resolving these issues was the studio's first priority, she added.

"We continue to partner with the Xbox platform team to analyse all data to make ongoing server-side adjustments to continually improve the matchmaking experience. We are also preparing additional content updates that will address existing campaign, UI, and other issues to improve the overall experience. With each update we will carefully analyse data to confirm that the improvements we’re seeing internally are also happening with fans at home."

Ross said 343 was also planning a number of server-side tweaks and game content updates over the coming weeks.

"Looking forward, I want to give you a high-level cadence of the latest updates we’re currently working on. Development and testing of our latest content update continues and we are on track for release later this week.

"We will update you on the status and patch notes of the content update once we have a better understanding of our release window. Only through making changes on both the “server side” (matchmaking and other server rulesets) and, via content updates (to the game itself), can we make the significant progress we’re working towards. And in the interest of expediency, we’re attacking the problem from both sides, non-stop."
