Halo MCC: joys and sorrows of the new update, the game does not run on the Steam Deck

Halo MCC

While we saw the long-awaited Halo Infinite last December, 343 Industries is continuing to systematically update the Master Chief Collection as well. The collection that includes all the main chapters of the saga is now available on both Xbox and PC consoles, and consequently also on the recent Steam Deck portable hardware. With the latest update, though, Master Chief Collection players are experiencing both joys and sorrows.



Right now 343 Industries has released a new patch for the Halo Master Chief Collection which introduces a series of innovations both for the third chapter of the saga and for its spin-off ODST. Specifically, there is a novelty that was highly anticipated by fans, and it is the possibility of playing in co-op in both campaigns of the titles even if the two users are playing on two different platforms.


If, like me, it no longer runs for you.

Delete this directory: "easyanticheat" in the installed folder.

Then you can at least play offline on Linux / Steam Deck like before.

This would at least allow you to play the collection in offline mode. In order to fully enjoy this experience proposed by 343 Industries, it will be necessary to wait for an upcoming corrective patch.





Halo MCC update breaks the game on Steam Deck and Proton

Halo MCC may be ‘unsupported’ on the Steam Deck, but plenty of players have been able to get the game’s campaigns up and running on Valve’s handheld (albeit on their lonesome). However, it appears that the most recent update to the game has rendered the FPS game unplayable on the portable gaming PC and other Linux Proton systems.


Easy Anti-Cheat (EAC) seems to be the culprit in breaking Halo MCC on Deck, but not in the way you might think. According to GamingOnLinux, the introduction of a new directory and files that should help get EAC up and running on the platform has actually “broken the game on Linux Proton / Steam Deck.”


GamingOnLinux notes there’s still likely work to be done in getting the anti-cheat software working on the Steam Deck, and there’s thankfully a way to get Halo MCC working again in the meantime. For now, players can delete the ‘easyanticheat’ directory in the installation folder, which should restore functionality to the level it was prior to the update.


While it’s unfortunate that this patch broke Halo MCC on Deck, it’s still great to see developer 343 Industries taking steps towards greater compatibility. Not only would native support allow players to team up with their buddies for co-operative campaigns, but it would unlock the power to jump into competitive Halo on-the-go too.

For those impatiently looking to get their Halo-flavoured fix, there are in fact some games from the sci-fi franchise that are officially ‘verified’ or ‘playable’ on the Steam Deck, and one in particular should greatly please RTS fans.
