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.
HARBINGER is a nightmarish action-horror adventure through the ruins of a mid-western American city ravaged by a cultic terrorist organization. In a world dominated by an advanced form of bio-terror, the only thing you can trust is the weapon by your side...
In 2030, humanity will be rattled by its inaction.
The wound left behind to fester has burst with its rot, and with it...
An enemy that alters the entire concept of life itself on its head...
They make their mark on the world through violent, ruthless attacks on civilization.
Who they really are is unknown, WHAT they really are is unknown...
But they've proven to have no interest in democracy, nor do they discriminate on the lives they alter and take.
Will you fight for the future of humanity? Or will you aid in the downfall of all life as we know it?

bio-terror and cultic activity,

Facing horrific abominations of science, you'll need to play smart to make it out alive.

spanning from the unkempt halls of your apartment complex, to secretive underground labs and toxic disposal facilities.
