Halo MCC Gets Steam Deck Support

Halo fans unite, we are getting official support! I’m an update today posted on Halo’s support website, a Halo: The Master Chief Collection update was pushed out to start enabling Easy Anti-Cheat for certain modes in the game. These include matchmaking, custom game browsing, campaign co-op, and Spartan Ops.

Be aware, there are some issues with the update that include possible freezing/crashing when leaving a party with other people and not being able to play some game modes with people who aren’t using Steam Decks:

Halo MCC Update Known Issues:

• 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

While we haven’t personally tested the update yet, our good friends over at GamingOnLinux has reported that the update is working as intended! Just a heads up that launching is backwards, so for right now, make sure to select the option to launch “without Anti-Cheat”, it will end up launching the game with it. I’m also looking forward to the future updates they will bring to increase compatibility further!
