The six-game Halo bundle now plays nice on the Steam Deck thanks to an anti-cheat patch.
You can now earn a Killtacular whilst on the move — yup, Halo: The Master Chief Collection has Steam Deck support.
The game, which first landed on Steam back in December of 2019, finally works on Valve's portable thanks to a fresh patch.
This long-awaited update for the game was announced on April 5, 2023, with the following note shared on the Halo Waypoint site:
Today’s update for Halo: The Master Chief Collection (MCC) enables players on Steam Deck to access modes that require Easy Anti-Cheat (EAC), such as multiplayer matchmaking and the Custom Game Browser. Future updates for MCC will continue to improve Steam Deck compatibility as well.
As noted by Gaming On Linux, the game did work in some capacity prior to this update, but this new patch improves the experience significantly.
The massive collection includes all of the single-player and multiplayer content from over a decade of Halo games, including Halo: Combat Evolved Anniversary, Halo 2: Anniversary, Halo 3, Halo 3: ODST, Halo: Reach, and Halo 4.
Despite this announcement, at time of writing, the $40 game is still showing as 'Unsupported' on the Steam store. But rest-assured, it does work.
