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.
The people in charge have defunded hospitals so you decide to help. With your squad of volunteer medics, plan your tactics, schedule actions and optimize the team strategy to heal as many patients as possible. 1-8 players, only the host needs to have the game installed. Modding support integrated.
The patients arriving at Lonchester hospital have ongoing medical and life issues. You can help them by administering the right kind of medicines. They will gradually reveal and share aspects of their lives with you.
Coordinate your volunteer medical squad, schedule your turns and enjoy figuring out the optimal strategy to heal each patient. Tabletop gamers might know this as "Action Programming". Decide which hospital equipment to upgrade and where to place items for maximum efficiency.
Similar to the Jackbox series of games, only the host player needs to have the game installed. Guest players join an online session by entering a 4-digit room code on their phone, PC or any other device with a web browser. Once connected to a game session, each player controls a character and/or becomes a dialogue writer via their connected device.
You can control multiple players/characters from a single device if you want to:
Play in single-player mode or
Share your device with a co-op buddy.
Turn-based and grid-based.
In single player you control two characters.
Maximum of 8 players in multiplayer mode.
Every round, patients lose health - heal them by using an optimal amount of turns.
After earning money from healed patients, decide which hospital equipment to buy.
Vote on where to place purchased and upgraded hospital equipment.
Improve your patient satisfaction scores and rank to unlock more hospital wards.
Deep modding integration: play other people's mods or make your own.
You can have up to 4 volunteer medics and 4 dialogue writers.
Volunteer medics play-out the core tactical gameplay.
Dialogue writers type the speech-text for patients and medics which is fun for players who want to join a session but are more creative than strategic.
Co OPERATION: MultiTurn is not *exactly* like any other game, so it’s quite difficult to say “it’s like game X but combined with game Y”. Having said that, if you enjoy tactical games where you have to think ahead, like Into the Breach, Wargroove, Shogun Showdown or Monster Train, you’ll probably enjoy this game. Co OPERATION: MultiTurn stands out when you play it with some co-op buddies. Coming up with clever tactics together and working out optimal strategies as a team is a really nice feeling. It’s typically pretty funny when your plans go wrong too.
We’re trying to make a multiplayer experience that helps people feel emotionally connected to each other. That’s (kind of) been scientifically proven! Groups of Masters level psychology students at Basel University evaluated an early demo and all agreed that it positively affects relationships. Here’s a quote from one assessor: “We felt that our relationship as a group was strengthened and we definitely got to know each other much better because of the game.”
Running hospitals is expensive. A clever bean in central government decided that tearing up requirements for medical qualifications would help. Volunteers are now welcome… throughout the country?! 🤷 You decide to enroll and help your local hospital. Find out what the patients need and form a strategy to help them. The more coordinated your team is, the more people you can heal!

To play online, screen-share your PC screen while on a video call. Guests join a session by entering the room-code on their web browser/phone. It doesn't really matter if one player has internet lag, the gameplay is designed so that lag doesn’t affect the fun.
We’re actively developing Co OPERATION: Multiturn. It was in closed-testing on Itch for [far too long] before we brought the demo to Steam. We appreciate all our player feedback and let it guide our plans. Many features were born from votes on our Discord and mailing list. We also have an ongoing collaboration with Plymouth University, with students from Plymouth making mods for Co OPERATION: MultiTurn. You can find them from the in-game modding menu. Documentation on how to make mods is also in-game.
