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 Horus Heresy: Betrayal at Calth is a turn-based combat epic set during the origin era of Warhammer 40k. Play on either PC or VR, as the game will detect your platform choice. Take command of Ultramarines as they battle against their traitorous brethren, the Word Bearers. VR HEADSET NOT REQUIRED.

Immerse yourself in the Horus Heresy the epic origin story
of the Warhammer 40,000 Universe!

The first shots have been fired in the conflict that will change the future of mankind. Brother Legions of Space Marines taking arms against one another. The noble Ultramarines are betrayed on Calth by the zealous Word Bearers bent on tearing down the Imperium. A dark ritual ignites the system’s star, sending both Legions underground to battle for their honor, their belief, the fate of the Imperium, or just to survive.

The Horus Heresy: Betrayal at Calth is a game of turn-based skirmishes between the genetically altered warriors of the 31st Millennium, The Adeptus Astartes. In the campaign, players control units of Space Marine Legionnaires, guiding them through the underground arcologies of Calth. Fight alongside units of Ultramarines ranging from basic Legionnaires, Veterans, and Sergeants, to elite units of Terminators, and the most venerable Contemptor Dreadnought. Dispatch the foul heretics of the Word Bearers using a mighty arsenal, from the ranged accuracy of Bolters, Plasma Guns, Flamers, and Rocket Launchers, to the close combat might of Chainswords, Power Fists, and Lightning Claws.

The Horus Heresy: Betrayal at Calth also includes several Multiplayer maps allowing players to fight as Ultramarines or Word Bearers in either objective based missions or deathmatch. Bring the full arsenal of your chosen Legion to bear against friends with private matches or against opponents across the world with built in matchmaking. Multiplayer mode is available to both PC and VR players, allowing both formats to play against one another.

VR NOT REQUIRED TO PLAY

Features

• Original Horus Heresy Narrative: Set in the 31st Millennium on the planet of Calth, Magos Ohmnal Sarc commands a unit of Ultramarines. When he discovers corrupted data in the data stream, Sarc is confronted with a faction of aggressive Word Bearers and a devastating plot of corruption within the Imperium that introduces untold threats and schemes against the Emperor. The original story was written by Black Library author Rob Sanders.
  
  
• A Living Battlefield: While players decide on their next action or wait on their opponent, the world around them continues to animate and fight.
  
  
• Multiplayer Skirmish Mode: Players can choose between the Ultramarines and Word Bearers factions.
