How to Play Minecraft on the Steam Deck

Looking to play Minecraft on your Steam Deck, with mods too? Here's how to do it.

Minecraft on the Steam Deck
Recently, the leading developer of PolyMC went on a political rant and removed all his co-developers from the project. We do not condone any form of bigotry.

Meanwhile, the other developers released a fork of PolyMC called Prism. This is the solution we propose you pick instead of PolyMC.

If you want to play Minecraft on your Steam Deck, with mods and everything, I recommend you install a little app called PolyMC Prism. It’s an unofficial launcher with fewer issues than the official one.

Here’s how you do it.

  1. Go to desktop mode. Click the Steam button, go down to Power, and then Switch to Desktop. Wait for the Deck to reboot.
  2. Click on the menu button and open up Discover.
  3. Search for PolyMC Prism. (If the keyboard doesn’t pop up, click the Steam Button + the X-button.) Install the app.
  4. Launch PolyMC Prism and add your account in the top right corner. You can use both your Mojang and your Microsoft login.
  5. Next, go into the main PolyMC Prism settings, click Minecraft in the left sidebar and click the option to close PolyMC Prism whenever the game window opens.
  6. Also, check if Java is set to the latest version.
  7. Click Add Instance in the top left. Either choose vanilla Minecraft or follow this guide to install mods.
  8. If you care, you can add Minecraft to the Steam Library. Open up desktop Steam, go to Library, and at the bottom left corner, click on the plus sign, then Add a Non-Steam Game.... Navigate to your installation folder and add PolyMC.

..and that’s that covered. You should now be able to play Minecraft on your Steam Deck with mods.

Enjoy your blocky worlds!
