Guide: Installing Procyon on Linux with Steam Proton

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.

What is Procyon? Features and Description

It's the future! And humanity is, predictably, under attack by extraterrestrial forces. Lucky for us we have an experimental ship that's never before been flown that will surely...uh, possibly...well, implausibly be able to win the war! All we need now is a pilot or two.

Key Features

Fight through five increasingly-populated shoot-em-up stages
Destroy a plethora of enemies (or, as we like to call them, "potential explosions")
Switch between two distinct weapons on the fly: bullets for lots of damage over lots of space and a locking beam for concentrating on those hard-to-reach areas!
Use your shields to zip unharmed through enemy attacks!
Overcharge your weapons on the fly for even more destructive power!
Original faux-orchestral soundtrack is like music to your ears! Because it IS music. For your ears.
Multiple game modes, from the start-at-any-level normal mode up to "I have but one life to give for my planet" survival mode.
Local co-op allows you and a friend (or even a complete stranger that you're willing to invite into your home, if you want) to team up and deliver double the delicious destruction!
Support for playing in portrait orientation for a true top-down shmup experience!
