Moon Sweepers on Steam Deck: rating and Proton status

Does Moon Sweepers work on Steam Deck?

Moon Sweepers can run on Steam Deck through Proton, though Valve still lists its official compatibility badge as Unknown.

On October 25, patch 1.0.4 fixed startup issues with older Proton versions on Steam Deck and Linux.

Is there a native Linux version?

No. Moon Sweepers only ships a Windows build on Steam, so SteamOS automatically runs it through Proton.

Do the Steam Deck controls need remapping?

The game includes full controller support and Steam Input, so the default Deck controls work without a custom remap for ordinary play.

What does the Unknown rating mean?

Valve’s Deck compatibility ratings describe the current status:

• Verified: Works on Deck out of the box.
• Playable: May need manual adjustments, such as choosing a controller layout.
• Unsupported: Currently does not work on Deck.
• Unknown: Valve has not checked compatibility yet. This is Moon Sweepers’ status as of October 29, 2026.

What to test first on your Deck

Make sure your game is updated to 1.0.5 (or at least 1.0.4, which added the Proton launch fix). If you are trying it on Deck for the first time, run through a quick solo check before building a massive factory:

1. Boot into the main menu and start a solo world.
2. Test movement, sweeping and the upgrade UI text size on the 800p screen.
3. Deposit a load of dust and buy a cheap upgrade.
4. Save, quit to the menu and reload the world.

How does it perform on Steam Deck?

Deck performance varies by settings and Proton version. Start on Medium graphics if you see stuttering or graphical glitches, then raise quality once the game feels stable. Patches 1.0.4 and 1.0.5 also improved Proton startup and late-game stability, so keep the game updated.

For desktop hardware specs, see the Windows system requirements. You can also check the platforms and controller guide or head to where to play for the Steam store link.
