This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.
1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."
Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.
Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.
2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.
3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.
4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.
A plague-mutated doctor fights through wave after wave of infected husks in this fast-paced roguelike pixel shooter. Equip cursed masks, wield biomechanical weapons, and mutate your build as you survive a kingdom undone by immortality.

Plagun is a grotesque roguelike shooter set in a post-apocalyptic kingdom rotting from a failed cure for death.
You play as a masked survivor—once a doctor, now a monster—using plague-infused weapons and cursed masks to fight back against an endless tide of regenerating horrors. Every corpse you collect strengthens your run. Every mask changes how you play. Every weapon is a twisted tool of infection.
Runs are short, intense, and always evolving. Choose your gear, survive escalating waves, and uncover the dark truth behind the plague that ruined the world.

Bullet-Hell Mayhem
Auto-shooting action meets tight platforming and fast, wave-based encounters.
Skull Mask Builds

Permanent Progression

Discover a fallen kingdom through environmental storytelling and cryptic logs.
Pick-Up-And-Die Gameplay
