Halo Studios released the first post-release patch for Halo: Campaign Evolved on July 29, 2026. This update matters because it addresses stability issues and AI behavior that affect gameplay across Xbox, PlayStation, and PC. Players on all platforms receive these fixes simultaneously with this release.
Halo Studios releases first post-launch patch for Halo: Campaign Evolved
The patch carries version number 16.754.404 and targets stability improvements on all platforms. It also adjusts AI enemy behavior to refine combat encounters. These changes apply uniformly whether players launch the game via Xbox consoles, PlayStation systems, or PC storefronts.
- XBOX File Size: 13 GB
- PlayStation File Size: 7 GB
- Microsoft Store/Xbox app PC File Size: 4 GB
- Steam File Size: 21 GB
- Update Version: 16.754.404
File sizes vary significantly by platform, with the Xbox version requiring 13 GB and the PlayStation version needing 7 GB. The Microsoft Store and Xbox app PC version is the smallest at 4 GB, while the Steam version is the largest at 21 GB. These size variations result from how each platform handles game assets and optimization.
PC players now see warnings for AMD and NVIDIA drivers with known issues before launching the game. The update also fixes Xbox Gamertag display problems during account linking for PlayStation and Steam users. Specific mission improvements include stability fixes for 'The Maw' and 'Pillar of Autumn', along with AI patrol adjustments in 'The Truth and Reconciliation'.
Known issues remain for some configurations, including cinematic stuttering on non-multiple-of-30Hz displays and crashes on Intel 13th and 14th generation CPUs due to microcode issues. We looked at the last Halo: Campaign Evolved update earlier, and several of the same balance and stability themes came up in this release. The developers are improving the game through specific updates instead of major changes.
