Microsoft released a new patch for "Halo: The Master Chief Collection" containing a set of updates. The latest patch includes bug fixes and solutions to matchmaking, parties and roster issues, among others. 

According to players, the matchmaking bug makes it quite difficult to find a match and there are uneven teams when matches are found. The previous patch allegedly included a fix for the issue, but it seems that the new patch truly resolves the problem. The latest one allows gamers to get discovered more quickly, do voice chats while loading the Matchmaking screens, and even has improved language support for Japanese, German, Norweigan and Spanish languages.

Meanwhile, developers of "Halo: The Master Chief Collection" swore to release more patch updates soon to fix the remaining bugs and issues found in the game and to compensate for the rocky launch of the collection. In order to release updates quickly, Microsoft delayed the release of the twin-stick shooter "Halo: Spartan Strike" to next year. 

343 Industries' chief Bonnie Ross apologized to gamers for the bugs, saying, "We have not delivered the experience you deserve. I personally apologize for this in behalf of us all at 343 Industries. Our team is committed to working around the clock until these issues are resolved."
