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.
Welcome to the Afgarn Mansion. Don’t ask why it’s empty. Nor why the lights flicker. The more you ask, the more they’ll want to answer. Find your father. If you hear voices, don’t respond. The experiments are still inside. They know you entered. And they’re eager to have you close.

The Story
Ryle received a strange letter from his father, after years of being away from home. In it, his father revealed that something had gone terribly wrong at the corporation where he worked. After a long journey, Ryle arrived deep within the Afgarn Mansion… and found that the security protocol had already been activated. The place was collapsing. He had only one option: find the key and get out before it was too late.
The protocol was clear:
“DO NOT speak to any experiments.”
As he moved forward, Ryle confirmed that several laboratories were still operational. The company had attempted to alter human DNA… and failed, fatally.
The experiments had survived. Mutated, hostile, and with unnatural abilities: phasing through walls, sensing movement… and something more.
They already knew he was there.
And they were waiting for him.

BRIEF EXPLANATION OF THE GAME:
Mechanics
In Haus of Irndrous, your stamina is limited—push yourself too hard, and you'll be in danger. Your flashlight is your only hope in the darkness, but it won’t always work. Each area contains puzzles that will test your observation and logic… all while you're being hunted by brutal enemies twisted by genetic experiments. They don't just want to catch you; they were designed to tear you apart.
Immersive Narrative
The story in Haus of Irndrous isn't handed to you—it’s uncovered piece by piece. Hidden radios, scattered notes, and the mansion’s eerie atmosphere slowly reveal the truth. Each audio log provides clues to solve puzzles or fragments of the dark past of the Afgarn Corporation and its inhuman experiments. Exploration and curiosity are rewarded, making you an active part of the mystery.

80s-Inspired Atmosphere
Dive into a retro nightmare. Haus of Irndrous draws heavily from the 1980s, blending the mansion's decadent elegance with period technology—vintage radios, VHS-style visual and sound effects. The result is a deeply immersive experience that evokes classic psychological horror.
Progression and Challenge
Every conquered area raises the stakes. Enemies become more aggressive, puzzles more complex, and environments more oppressive. The constant sense of danger makes every bit of progress feel like a true victory.
