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.
Step into Serene Estates: Last Guy, a 3D action-adventure inspired by the golden age of early 2000s classics. Explore a surreal housing complex where Y2K optimism meets abandoned brutalism. Hack robots, fight, and uncover the secrets of a system that keeps running long after humanity’s gone.
Awaken in the Serene Estates, a vast underground housing facility built to shelter humanity from the dangers of the outside world.
For generations, its residents have lived in controlled comfort, their lives guided and monitored by the omnipresent AI matron, Serena. Order was promised. Safety was guaranteed.
But something has gone wrong. You are D-5.Omega, one of the last conscious residents to awaken from a life spent inside the simulated dream of the Actuaverse. Small, fragile, and unprepared, you must now navigate a facility that has come alive in ways it should not have. Every corridor is watched, every system is armed, and Serena herself has marked you as an intruder.
Serene Estates was built on security, and its systems will not let you go without a fight.

● Drones patrol the air, able to repair, maintain, and eliminate.
● Security cameras are Serena’s eyes. Step into their vision and alarms, locks, and worse will follow.
● Turrets deploy automatically, shredding anything caught in their sights.
● Hazards of the facility itself—electrified water, industrial fans, toxic gas, and endless shafts—turn the structure into a labyrinth of lethal design.
Though frail, D-5.Omega is not powerless.
● Climb and traverse hidden routes to outmaneuver surveillance.
● Hack terminals to seize control of RC drones, turning Serena’s machines against her.
● Use energy cells to power up dormant systems, open locked paths, or manipulate the environment to your advantage.
● Soy Breeze vending machines keep you alive with a health boost.
● Bug Lite, rare and hidden, permanently expands your health pool when found and purchased with special tokens.
● Escape Keys unlock the pods of still-sleeping residents. Collect them all to rescue everyone and reach the best ending.

● Atmospheric exploration through a colossal underground facility built on order and surveillance
● Stealth and strategy to avoid cameras, alarms, and patrols
● Deadly hazards and enemies that force creative navigation and quick thinking
● Hacking and drone control for indirect combat and puzzle solving
● Lore-rich environments that reveal the unsettling truths behind Serene Estates, its corporate backers, and the Actuaverse
● Multiple endings depending on how many you save or leave behind

Life inside Serene Estates was supposed to be safe.
Now the walls themselves have become a prison.
Will you escape Serena’s grasp, or be her last obedient resident?
