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.
A tactical Vietnam War shooter with open mission areas. Infiltrate, ambush, or go in loud. Customize weapons, use vehicles, and play solo, in coop, or PvP. Create missions with the built-in editor.
What started as a routine mission turns into a fight for survival deep in hostile territory.
Move through jungles, villages, and military outposts, choosing how you approach each situation. Stay quiet, set up ambushes, or go in loud when things escalate.
The battlefield reacts to your actions, and missions shift between open areas and more directed encounters. Play the full campaign solo or in 2-player coop and fight your way back - one step at a time.
Every encounter can be handled differently. Stay quiet and eliminate targets up close, fight through enemies with rifles, or use heavy weapons when things get out of control. At longer distances, precision matters just as much.
Fights shift fast, and reacting at the right moment can decide whether you push forward or get overwhelmed.
Earn new attachments through side objectives or by actively using your weapons. Each weapon progresses individually, unlocking new options over time.
Attachments offer both benefits and drawbacks, giving you control over how your weapon performs in different situations.
Use land vehicles, helicopters, and boats to move through the battlefield and support your mission. Reposition quickly, outmaneuver enemies, or bring mounted firepower into the fight when needed.
Vehicles are based on authentic military equipment used during the Vietnam War.

Earn experience, climb the ranks, and track your performance with detailed statistics. Every weapon features its own progression system and stat tracking, allowing you to refine your playstyle and optimize your loadout.
Unlock attachments, expand your arsenal, and showcase your progress in multiplayer. Whether you play solo, in coop, or in PvP, all modes contribute equally to your progression.
