Halo: The Master Chief Collection gets Steam Deck support

By - | Views: 58,993

It took quite a while for the issues to be figured out but Halo: The Master Chief Collection (MCC) now has improved Steam Deck support. This should also mean it works better on desktop Linux too.

While the game did somewhat work for a while, you weren't able to play fully online with others due to problems with Easy Anti-Cheat. Whatever the issues were have been partially solved now so players on Steam Deck can jump into EAC enabled games in multiplayer matchmaking and the Custom Game Browser. In a support post on the official site, the developers said that future updates will "continue to improve Steam Deck compatibility as well".

Testing it myself and yup — playing online works just fine:

There's some known issues though, like the launch options being backwards, that you need to keep in mind for now until future updates:

  • 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.

By "PC", they of course mean specifically Windows in the above quoted list.

For people trying it on Steam Deck for the first time, just be aware it won't automatically bring up the on-screen keyboard to sign in. You need to press STEAM + X to have it appear, and it may take a few taps in the input box to have it actually get focus from the keyboard. Hopefully they work on that too.

Quoting: ElectricPrismThanks I added it to my radar,
No problem! It doesn't seem to be mentioned on the Steam listing, but Bail or Jail does have local split-screen, so if you're using external monitors it should definitely be alright.

Quoting: ElectricPrismI often use the term LAN ambiguously loosely. However with the world events of the last few years and the Internet not being guaranteed with possible war on the horizon I am skewing away from putting my eggs in just one basket.

So -- "That Offline LAN functionality" has increased in value to me as a consumer -- I bought and downloaded a bunch of games on GOG (and I don't even really like GOG that much) just because they're more future-proof ready to go if the Internet goes out.
Like fellow GOL'er StoneColdSpider, I make my home-base in Emulationville, so outage-proof future-proofing lies with the classics, for me.

exciting news
Has anyone been able to get this working on desktop?

I've tried with EAC enabled and disabled. I get different errors. When I check enabled, it tells me that EAC is disabled. When I check disabled, it tells me: "Contacting Server. Connecting to transport service. Please wait." And it will load forever.

Others have been getting this on desktop as well:

I'm trying with Proton 8.
