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.

Systematic Immunity is a challenging precision platformer set inside the human body...and not a particularly healthy one either. This body has been infected by a big, nasty bugger of a germ, who is making it his business to spawn many more germs as fast as he can.

Systematic Immunity is a challenging precision platformer set inside the human body...and not a particularly healthy one either. This body has been infected by a big, nasty bugger of a germ, who is making it his business to spawn many more germs as fast as he can. You and your mob of 20 white blood cells must put a stop to his shenanigans at all costs!

Use all your skills to run, jump, roll, float, bounce and teleport your way through the inhospitable tissue of your host human. But remember, each white cell can only kill one germ. So watch out for casualties!

Key Features

• Control your cells using the keyboard or XBox 360/One controller
  
• Play through 75 levels spread through 3 organs
  
• Defeat boss germs in each organ
  
• Collect info snippets about the human immune system and biology
  
• Unlock extra levels with their own collectible info snippets
  
• Create your own levels to play and share

“Puffing myself into a balloon to toot around floating islands of death spikes, even if it seems slightly off textbook white blood cell behavior, is extremely fun.”
7/10 – The Cube

“While the fact-gathering adds a new dimension to the game and makes it stand out from similar games in the genre, the visuals are also alluring – cute and cozy – and, if I had the chance, I would live in this colorful body!”
4.5/5 – Indie Game Reviewer
