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.
Dive into the Ocean Keeper – a cooperative roguelike where four survival miners defend their Mech Spider, fight with endless hordes of monsters, and dig for resources. Team up with your friends, upgrade between waves, and survive the deep caves, full of treasures… if you can.
Fight endless waves of monsters, protect your Mech Spider, and mine resources in Ocean Keeper, a survival co-op roguelike. Play as one of four miners, upgrade your gear and Mech, and explore underwater dungeons. Face the ocean’s dangers and do whatever it takes to stay alive.

Team up with your friends and climb into the Mech Spider to kill thousands of monsters. Work as a team to protect your Mech – if it goes down, your crew will be defenseless against hordes of creatures.

Take a rest from endless battles and explore the caves in search of valuable resources and rare artifacts. But don’t get too comfortable – your team has just one minute to mine, upgrade your gear, and get ready for the next wave. If you are brave enough, you might find something truly powerful… just in time to face the bosses.

Mine resources from the ocean depths to unlock and upgrade powerful gear. Choose from 9 unique weapons – each with its own range, strengths, and playstyle. Don’t forget to coordinate with your team and plan your loadout beforehand: strategic positioning is key to protecting your Mech and surviving the endless waves.

In Ocean Keeper, no two waves are ever the same. Each brings new challenges, enemies, and opportunities for your team to adapt, strategize, and survive various underwater adventures. Upgrade your gear differently every time, uncover rare relics, and battle frightening bosses – you will never experience any run twice.
So gear up, dive deep, and may your Mech legs never rust.
Good luck, survival miners – the ocean is waiting.
