Halo Studios says a major update for Halo: Campaign Evolved will arrive sometime between August 17 and 21, bringing fixes for stuck AI teammates, tougher combat balancing and new graphics options across every platform the game runs on.

The developers have highlighted five main areas of change. Sergeant Johnson’s AI will no longer block mission progress in certain spots, and Jackals will stagger more reliably when players shoot at their arms and legs instead of relying on headshots alone.

Two more fixes address specific bugs. Infantry and Flood-infected enemies will now correctly fire their assault rifles when the Magnified Skull is active, and players will be able to fully disable chromatic aberration and film grain in the graphics menu, on top of general stability improvements across platforms.

Halo Studios has also issued a warning alongside the update. Save files created mid-mission will stop working once the patch installs, so the studio is advising anyone deep into a level, especially on higher difficulties, to finish that mission before the update lands next week.

The patch arrives as the game tries to shake off a mixed launch. Campaign Evolved landed with a Metacritic score of 81 and analysts have described early sales as soft, pointing to its price against a package that skips competitive multiplayer. Halo co-creator Marcus Lehto has also criticized the absence of split-screen play, calling it a planning failure.

Campaign Evolved sits inside a larger, more unusual production setup. Reports describe Microsoft‘s next Halo project as involving as many as fifteen different studios, with Halo Studios, the team formerly known as 343 Industries, acting more as a central hub than a traditional single developer.

That restructuring has had consequences of its own. Following the game’s launch, several contractors saw their contracts lapse or end, part of the wider reset Xbox chief Asha Sharma has been carrying out across Microsoft’s gaming division, though reports indicate no full-time staff were let go in this round.
