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 third-person sci-fi survival horror shooter. Enter the Green Dungeon, battle AI-transformed enemies, and uncover the devastating truth behind a monster born not from evil, but from a mother's grief. Explore, survive, and face what hides in the dark.
Some doors are not meant to be opened. Some grief is not meant to be survived.
People are vanishing. No bodies. No traces. Only whispers — and a place the missing all had in common.
The Green Dungeon.
You are sent in with one mission: find out what's happening. Report back.
Nobody warned you about what grief looks like when it stops being human.
A Monster Made of Love and Loss
She was a mother once.
When her child died, she refused to accept it. She turned to AI — not as a tool, but as a lifeline. A way to feel less. A way to forget.
It worked.
The more she gave herself to the machine, the less the pain could reach her. Until one day, the pain couldn't reach her at all.
She didn't become a monster out of hatred.
She became one out of love she had nowhere left to put.
Inside the dungeon, she doesn't have to remember.
Inside the dungeon, her child never died.
She will not let you take that away from her.
The Other One
Deeper in the dark, something speaks.
A mother. Like her. She came here for the same reason — and became something else entirely. Her body is gone. Her spine, taken for research. Only her brain remains, kept alive, wired to a device that lets her talk.
She knows everything.
She's been waiting for someone to finally listen.
