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.

Building on 10 years of constant engine development, ARMA II boasts the most realistic combat environment in the world. It models real world ballistics & round deflection, materials penetration, features a realtime day/night cycle and dynamic wind, weather and environmental effects. The simulation of a combat environment is so effective, the engine forms the basis for training simulators used by real armies the world over.
Although ARMA II is set in the fictional ex-soviet state of 'Chernarus' the gameworld is actually a 225 square kilometer chunk of the real world! ARMA II's highly detailed landscape is a meticulous facsimile of real terrain, modeled using extensive geographical data. This recreated region is brought to life with spectacular environmental effects and populated with dynamic civilian settlements and wildlife. Wild animals roam the atmospheric forests while the people of Chernarus try to live out their lives among the war-torn streets.
The 27th U.S. Marine Expeditionary Unit have been deployed to the former soviet country of Chernarus in this third installment in the series of award winning PC war simulators from Bohemia Interactive, creators of Operation Flashpoint*: Cold War Crisis and ARMA: Combat Operations.
Force Reconnaissance Team “Razor” are among the first to fight. This elite five-man team are about to fall down the rabbit hole, trapped in a war not only for control of the country, but the hearts and minds of its people. With the might of the USMC offshore and the Russians anxiously watching from the north, the stakes couldn't be higher. The fate of Chernarus is balanced on a razor's edge...
