Minecraft Dungeons II does not run on Linux, and Mojang says its team is working on it
Minecraft Dungeons II arrived on Steam on September 29 at $29.99 in the US, and it does not start on Linux or SteamOS. Mojang Studios has answered the complaints in a pinned official reply on its own feedback site: "We've seen your feedback about Steam Deck support for Minecraft Dungeons II. The team is working on it and we hope to have more to share soon. Thanks for your patience, and keep the feedback coming."

The block is not subtle. Steam's own store data for the game lists Windows as the only supported platform, with macOS and Linux both set to false. The game is developed by Mojang Studios and Double Eleven and published by Xbox Game Studios.
The game asks for Microsoft's Gaming Services and then stalls
The compatibility report on Valve's own Proton issue tracker was opened at 08:46 UTC on September 29, hours after launch. It describes the failure in one line: "The game asks to install Gaming Services, after clicking Yes, the game runs as a zombie, with no window spawning."
Gaming Services is Microsoft's own Windows component, and it is the piece Proton cannot supply. A commenter in the same thread narrowed it further, writing that the missing library "is xgameruntime.dll in System32" and that running the main game binary instead of the launcher crashes instantly. That is one owner's diagnosis rather than Valve's or Microsoft's, so treat it as a lead rather than a confirmed cause.
The thread has passed 350 comments. Owners reporting the same failure name Arch Linux, CachyOS, Bazzite 44 and Fedora 44, and say they tried Proton Experimental, Proton 11, Proton-GE and proton-cachyos with the same result each time. What none of that establishes is scale: nothing published says how many buyers are affected, or that every Linux configuration fails.
What Mojang's reply does and does not promise
The reply on Mojang's feedback site runs to three sentences and carries no date on the page. It answers a request for Steam Deck support, and it says the team is working on it.
It stops there. There is no date, no version, no commitment that support will ship, and no mention of Linux or SteamOS outside the Steam Deck, which is the same operating system on different hardware. For a reader with a Steam Deck, a Steam Machine or a SteamOS desktop, the honest summary is that the developer has acknowledged the problem and nothing more.
A familiar pattern for Steam Deck owners
This is the second game blocked on SteamOS the site has covered since late September: For Honor stopped running on Steam Deck and Steam Machine, for a different reason. What the two share is the shape of the problem: a Windows-side dependency the publisher controls decides whether a SteamOS machine can run a game at all, and Valve's compatibility layer cannot supply a licensed Microsoft component on its own.
Valve has said nothing about Proton support for Gaming Services in the thread, and buyers asking for it there have had no answer. Minecraft Dungeons II remains on sale at $29.99 in the US with Windows listed as its only platform, which is the one fact on the store page that has not changed since launch.
