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.

Encounters filled with unknown dangers
Equip specialized weapons to enhance your class abilities
Different classes can equip their corresponding signature weapons, allowing each character to unleash their full potential.

Scavenge for resources and struggle to survive
Resources are scarce and filled with danger. Every expedition may lead to a breakthrough—or a disaster. You must make critical decisions with limited supplies to ensure you survive long enough to reach the next floor.
Unique tactical, turn-based combat system
Combat is built on a predictable yet deeply strategic grid-based system. Players must carefully consider positioning, skill timing, and enemy behavior patterns.
Enemies with randomized attribute enhancements
During every run, enemies may gain random enhancement traits, turning familiar foes into unpredictable threats and forcing you to adapt your strategy.

Stronger Enemies
In the deeper areas, you’ll encounter more powerful foes — enemies with higher defenses, deadlier attack patterns, and unique abilities. Stay cautious and use your resources and strategies wisely if you hope to survive.

Forge Your Own Combat Build
Master the four core attributes, enhance your team’s capabilities, and build the strategy that suits you best.
Collect special chips to accelerate progression
Learning Chips can be used to enhance core attributes and accelerate your character’s growth.

Access recovery, training, and insight functions in specific areas
In designated rest areas, you can use Recovery to regain HP through short rest, Training to consume Chips for ability upgrades and faster EXP gain, and Insight to operate surveillance systems that remotely reveal sections of the map. These features provide breathing room between encounters and allow you to plan ahead for the increasingly dangerous zones ahead.

Out-of-run upgrades unlock new classes and enhance abilities
By earning special points during gameplay, players can unlock additional character classes and passive upgrades, encouraging them to continuously experiment with different playstyles.
Carry over EXP and CV into a new run
After each cycle, accumulated experience and special currency are carried over, giving you an advantage in the next run and reinforcing the long-term progression of a roguelite structure.
Collect story fragments to uncover the truth behind the disaster
Scattered research logs and fragmented documents can be found throughout the facility. Piecing them together gradually reveals the laboratory’s secrets and the true cause of the disaster.
