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.

In this open-world real-time strategy game, you're tasked with finding patient zero before an alien virus takes over San Francisco. Command your squad, defend your base, and stop the Pangu virus.

Cepheus Protocol is an open world real-time strategy (RTS) game where a mysterious virus of alien origin is sweeping through San Francisco. It is up to the Center for Epidemic Research and Control (CERC) to track down and find Patient Zero before it is forced to enact the cepheus protocol. Command your squad, defend your base, and stop the Pangu Virus before it is too late - how you do this is completely up to you.

• Train and level a single squad of up to 8 members as you search the city and battle the infected.
  
• Build and train defenders to safeguard your base from the Pangu Virus’ victims as they will attempt to retake zones.
  
• Collect DNA in order to research the virus and defeat Patient Zero.

• Take command of Captain Adrian Winter as she leads an 8-member squad of elite soldiers in an attempt to stop the Pangu Virus from spreading beyond containment.
  
• Choose how to spend your in-game money on upgrading your barracks, buying better weapons, or acquiring new soldiers to fill your ranks. You earn in-game money by completing bounties and eliminating the infected.
  
• Collect viral samples to better improve your squad’s abilities and expand your understanding of the virus before it is too late.
  
• Every life matters and every soldier counts. If Captain Winter dies, it’s game over. Decide whether to leave her at the base or use her advanced skill-set to even the odds while in the field.

In the farthest reaches of the frozen Antarctic ice shelve, Chinese researchers discovered a 4.8 billion-year-old meteorite that had microscopic alien organisms deep within the rock. Decades later, after a Special Forces raid to retrieve a sample of the virus that had been cultivated from the discovery, Chelsey Trader is accidentally exposed to the Pangu Virus.

Becoming Patient Zero, inadvertently, she spread the virus, which infects innocent civilians which are mutated into monstrous beings under her control.

• Building: At the onset of the game, you’ll be able to build a base comprised of specialized buildings where new soldiers can be trained and weapon upgrades can be bought.
  
• Defenses: As the threat from the virus grows, your base is at constant risk of being overwhelmed as random and planned encounters from the infected threaten to overrun your only means to stop the outbreak.
  
• Patrolling: As the infection grows, more and more parts of the city fall to the Pangu Virus. You must send out patrols to each section of the world and destroy toxic gas towers that spread the virus at an alarming rate.

The Pangu virus grows stronger by the minute. Complete missions and destroy infection pods throughout the map to lower its spreading rate. Be warned, each soldier under your command is equally at risk of becoming infected.

• Command Captain Winter as your powerful hero character.
  
• Train soldiers across various disciplines. These include assault, heavy weapons, spec-ops, sniper, scientist, and medical.
  
• Use tactical awareness to slow down time and get out of sticky situations!
  
• Use different squad formations to give you a tactical edge over the infected.
  
• Utilize the specialized units and different team dynamics for maximum effect.
  
• You’ll have access to other tools such as carpet bombs, ammo drops, and more!

“Cepheus gameplay is a unique blend of RTS with a real tower defense feel. 100% a strong learning curve to master the tactical skills layered across the six different character classes. Check it out!”
