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.

Fight a real AI that thinks, adapts, and shows you its reasoning live. Battle through procedurally generated wireframe mansions or spectate five AI labs fighting each other in endless deathmatch. No difficulty settings. No hand holding.

MANSION is the world's first FPS where you fight a real AI.

Every enemy in the mansion is dangerous. But one of them is different. The Commander is powered by a genuine artificial intelligence that makes real tactical decisions in real time. It flanks. It retreats. It adapts. You can watch it think.

CAMPAIGN MODE

Fight through procedurally generated wireframe mansions. Clear every hostile before time runs out. Each level gets harder. The AI Commander hunts you through every one of them, regenerating health, dodging your shots, and making decisions you can read live on screen through its thinking terminal.

One gun. Limited ammo. A 10 second death penalty. No difficulty settings. No hand holding.

AI ARENA MODE

Watch five AI agents from five different labs fight each other in an endless deathmatch. Claude. GPT. Gemini. Grok. Llama. Each one making independent decisions, flanking, shooting, and eliminating each other while you spectate. Kill tallies accumulate indefinitely. Every fight is different.

FEATURES

Procedurally generated mansions that change every run. A real AI enemy that thinks, adapts, and shows you its reasoning live. AI Arena mode with five AI agents fighting autonomously. Full controller support with adjustable sensitivity. 3D spatial audio with positional gunfire. Wireframe sci-fi aesthetic with nebula skybox. Arcade scoring with kill streaks, popups, and high score tracking. Original soundtrack.
