Today’s update for Halo The Master Chief Collection enables players on Steam Deck to access modes that require Easy Anti-Cheat (EAC), such as multiplayer matchmaking and the Custom Game Browser. It was also mentioned that future updates for MCC will continue to improve Steam Deck compatibility as well.
Halo The Master Chief Collection Known Issues
Alongside this update, the team has added three Steam Deck issues to our Known Issues list:
- When launching Halo: The Master Chief Collection on Steam Deck, selecting one of the available Anti-Cheat launch options will result in the game launching with the opposite launch option. For example, selecting “Anti-Cheat Disabled” will result in MCC launching with Anti-Cheat enabled.
- Until this issue is resolved in a future update, players on Steam Deck must select the “Anti-Cheat Disabled” launch option to access multiplayer matchmaking and the Custom Game Browser.
- Shortly after being removed from or leaving a party with other players via the Roster menu, players on Steam Deck may experience Halo: The Master Chief Collection freezing or crashing.
- Players on Steam Deck are unable to play Campaign Co-op or Spartan Ops with players on PC or Xbox consoles. Attempting to do so may result in players accessing gameplay, however, all sessions will eventually experience a “Connection Interrupted” error or a similar disconnection.
- Campaign Co-op and Spartan Ops will function as expected if all players in the group are playing on Steam Deck.
