343 is back again with another Halo: Master Chief Collection update, and July 2023's drop feels busier than ever with big changes to Firefight, Halo 3 game mode support and more.
The headline additions are for Firefight in this month's update, with plenty of new options coming to the collection on July 12th. The team is (finally) adding the ability to join Firefight matches in progress, which means you don't have to start from scratch to get playing some MCC PvE. This is true for both public and custom games, and Firefight matches will also be added as a new option for the Custom Games Browser as a result of the new join-in-progress options.
