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.
Explore, build, and survive in the depths of a forgotten world. Manage oxygen, power, and resources as you uncover the secrets buried beneath the surface.
The surface is gone.
Toxic dust has claimed the air, and what’s left of humanity hides beneath mountains of rock.
You are D. Kellan, maintenance engineer of Research Center 08, sent deeper and deeper to keep the last bunkers alive… and uncover what happened to Bunker 09.
Every descent is a risk.
Every meter you dig reveals collapsing caverns, abandoned structures, and geological anomalies.
And the further you go, the stranger and more hostile the world becomes.
Explore procedurally generated tunnels, swing across vertical shafts with your grappling hook, gather resources, build underground shelters, and keep your base breathing—literally.
The environment itself fights back: sand falls, water spreads, lava eats through the rock.
Afterdepth blends exploration, survival, and narrative in a dense, atmospheric underground where your only light is the one you carry with you.
Breathe carefully.
• Procedural underground world – unique caves every time you descend.
• Dynamic physics simulation – sand, water, and lava in real-time.
• Grappling hook movement – reach dangerous spots, escape collapses, traverse massive caverns.
• Base building – manage oxygen, energy, structure, and survival.
• Narrative exploration – uncover logs, equipment, and the secrets of Bunkers 08 and 09.
• Hostile environment – every resource matters; every mistake has consequences.
• Sandbox Mode – experiment with physics and building freely.
• Atmospheric pixel art – deep lighting, shader effects, and a heavy, underground mood.
Descend, discover, and see what humanity left buried—and what awakened after it.
