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.
When your father’s whereabouts become unknown, your mission is to venture into this mansion in the middle of nowhere to uncover the mysteries hidden within. But beware—you are not alone. Datagames Studios presents an survival horror experience where sound is your greatest—and only—ally.

When your father disappears without a trace, your mission is to venture into this mansion in the middle of nowhere to uncover the mysteries it hides. But be careful, you are not alone.
Datagames Studios presents an experience in which sound is your greatest—and only—ally.

In Lost Files: 1978, you find yourself alone in the face of danger.
Without sight, you move forward in complete vulnerability, so you must make sounds (gunshots, footsteps, throwing objects) or interact with your surroundings.
Each pulse momentarily reveals walls, objects, and hidden presences through sound waves... but there is a price: every noise also gives you away.

Inspired by survival horror classics such as Resident Evil, your goal is to escape by solving puzzles and exploring the mansion while a presence relentlessly stalks you. Use the tools to your advantage, stay out of sight, find hiding places when danger approaches, and shoot only when necessary.

Delve into the mansion and search for traces of your father: gather hidden clues, examine every corner, and solve environmental puzzles to unlock new paths to the truth.

In 1978, the story is not told through cutscenes or long texts: it is embedded in the mansion. Every room, object, and riddle is part of the narrative. Explore, connect clues, and solve the associated puzzles: each player can reconstruct, at their own pace, the truth hidden in Estancia Santa Rosa.
Datagames Studios was born as a way to express our ideas in video game format, exploring experimental proposals and unusual combinations. This is our first commercial project and marks the beginning of an anthology of experiences under the name “Lost Files,” where each installment tackles a new case, a new place... and a new truth to be discovered.
