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.

Windows Pc Requirements

Minimum:

• OS *: Windows 10 (or Windows 7 if you still refuse to update)
  
• Processor: A potato with a pulse. (Any Dual Core CPU from the last decade. Single-core speed is king here because the engine doesn't know what "multithreading" is).
  
• Memory: 4 GB RAM
  
• Graphics: Integrated Graphics. If it can render a spreadsheet, it can render this game.
  
• DirectX: Version 9.0c
  
• Network: Broadband Internet connection
  
• Storage: 500 MB available space
  
• Additional Notes: A mouse is required. Touchpads are a death sentence.

Recommended:

• OS: Windows 10 / 11
  
• Processor: High-frequency CPU (3.0GHz+). The engine runs on a single core, so throw raw speed at it.
  
• Memory: 8 GB RAM
  
• Graphics: Dedicated GPU (Not for the game, but so you can watch YouTube while you wait for the Round Restart).
  
• Network: Broadband Internet connection
  
• Sound Card: Any. You need to hear the distinct hiss of a Xenonid behind you.

The year is 2182, but the engine is from 2003. Join the Falling Falcons in a massive tactical deathmatch RP fest held together by spaghetti code and duct tape. Build bases, perform surgery, or evolve as the Hive. It's laggy, it's complex, and it is the most fun you will have dying in space.

The year is 2182. High Command has dispatched the USS Almayer to the frontier. You are a member of the Falling Falcons - 2nd Company, 2nd Battalion, 4th Brigade.

Your orders are simple: Respond to an unknown distress signal, secure the colony, and neutralise any threats. But on the rim of known space, nothing is ever simple.

BYOND: Build Your Own Net Dream

Built on the ancient, accursed, yet still beloved BYOND platform, this isn’t regular SS13; it's a completely overhauled multiplayer roleplay tactical disaster simulator. It looks like a game from the 90s, plays like a milsim from the future, and breaks like a cheap lawnmower.

Whether you are holding the FOB, performing open-heart surgery in a sand pit, or playing a xenonid trying to figure out how to open a door, your actions define the round. Every bullet must be accounted for, every wound requires surgical precision to treat, every host must be incubated, and every order must move down the chain of command.

KEY FEATURES

• Massively Multiplayer: Theoretically high player counts allow for full company-scale operations, meaning lots of people screaming over the radio at once or complaining that the Empress is micromanaging the hivemind.

• Complex Medical System: Health isn't just a bar. Treat broken bones, internal organ failure, and overdoses. If the xenonids don't kill you, the medic mixing up the labels on the pill bottle might.

• Destructible Environments: Blow open walls with C4, weld doors, or burn down the entire jungle because you saw a spider.

• Logistics & Command: The war isn't won by shooting alone. It’s won by the shipside support crew, including the Requisitions Officer, who orders the ammo for your rifle, and the Executive Officer, who really didn't mean to accidentally orbital bombard Delta Squad.

• Roleplay First: Immerse yourself in the hierarchy. Follow orders, shout tactical info over the radio, and engage in the unique "culture" of the Falling Falcons.

• Emergent Storytelling: Will you hide in a locker for 45 minutes as a suvivor? Will you robust a xenonid with a toolbox? Or will you succumb to liver failure after finding the colony's vodka stash?

• Corporate Interests: Roleplay as a Liaison from a shadowy company that cares more about the quarterly profit margins than your survival.

• Hostile Third Parties: Sometimes it’s insurgents. Sometimes it’s high-tech hunters. Sometimes it’s just the Military Police arresting you for not wearing your helmet.

  ⚠️ WARNING: READ BEFORE ENLISTING ⚠️

  1. Ancient Technology: This game runs on BYOND. When you click "Play" on Steam, it will install the BYOND requirements for you. Yes, you sometimes will get an popup for Byond Premium when it boots up. Lummox JR has to eat somehow. 

  2. The Learning Cliff: The controls are not intuitive. You will accidentally shoot your foot. You will drop your gun in the middle of a firefight. You will struggle to open a bag of chips.

  The UI looks like the cockpit of a 747-800. Take a moment to read the starter guide, call a Mentor (F1), or just ask the Marine standing next to you how to put your helmet on. We were all bald and confused once.

  3. Roleplay Expectations: aka Yes, you have to play as a Character. This is a Medium Roleplay (MRP) environment.

  • Names: Name your character something believable, not "xx_Headshot_King_xx" or "Obi-Wan Kenobi."

  • Behaviour: You are a Marine (or a giant bug). Act like one. If you run around griefing your teammates or screaming internet memes in the chat, you will probably hear the dreaded Bwoink. That is one of our volunteer Moderators coming to have a very polite conversation with you about your life choices.

  4. The Rules: Read them. They exist to keep the chaos fun, not frustrating. If you break Marine Law, the MPs will arrest you. If you break Server Rules, the Admins will probably ban you without much fanfare.
