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 psychological horror simulator where every playthrough is unpredictable. Face ever-changing events, sounds, and rules in a haunted house filled with hostile entities. You can't predict. You can't learn. You can only survive… or break.
Under The Floor is a psychological fear simulator where every playthrough is unique… and every minute could be your last.
You are alone in an abandoned house, overrun by hostile entities.
Your goal: survive as long as you can, then attempt to cleanse the place.
But nothing plays by the rules.
Every session generates a different combination of events, sounds, apparitions—even the rules themselves.
What you think you’ve learned won’t help you next time.
Sounds shift.
Entities behave differently.
Mechanics evolve.
The environment turns hostile in new and unexpected ways.
You can’t learn. You can only survive.
Your only weapon is your instinct.
Hide in the shadows.
Listen for signs of movement.
Anticipate what you don’t yet understand.
Sometimes, running is your only option.
And sometimes… even running won’t be enough.
Under The Floor isn’t just another horror game.
It’s a nerve-wracking, unpredictable experience.
A true test of your mental endurance.
🎲 Randomized events, sounds, and rules each time you play
👻 Unpredictable entities that adapt to your behavior
🧠 Constant tension without cheap jumpscares
🏚️ Free exploration of an increasingly hostile house
🔁 High replayability — no run is ever the same
