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.
Command any of 261 real-world countries in this 2026 grand strategy game. Build your economy, lead armies, and navigate deep diplomacy. Features built-in modding support and 12 supported languages. Shape the global order through espionage, nuclear deterrence, and AI-driven geopolitics.
Available Now in Early Access
Global Protocol: New World Order is a data-driven grand strategy game set in the real world of 2026. Play as any of 261 playable countries — from global superpowers to developing states — and navigate the complex web of modern geopolitics, economics, warfare, and diplomacy.
Every country starts with real-world data: GDP, population, military strength, alliances, resources, and political systems. What happens next is up to you.
Choose from 261 playable countries, each rated on a 5-star difficulty scale. Lead the United States and maintain global hegemony, guide Brazil through economic transformation, or take on the ultimate challenge with a fragile state fighting for survival. Over 4,600 provinces cover the entire world — every region matters.
Diplomacy goes far beyond simple alliances. Negotiate trade deals, impose multilateral sanctions through the UN Security Council, form and break military pacts like NATO or the Shanghai Pact, join economic blocs, and compete for prestige on the world stage. The G7, G20, and UNSC are active bodies whose decisions reshape the global balance of power.
Each country is governed by its own AI personality — aggressive, cautious, opportunistic, or isolationist. 68 scripted events draw from real-world 2026 flashpoints, while procedural events react to your decisions. Alliance betrayals, economic crises, border disputes, and regime changes unfold dynamically. Every action has consequences that ripple across the globe.
Deploy infantry, armor, artillery, fighters, bombers, helicopters, destroyers, submarines, and carriers across a detailed world map. Establish air superiority, blockade enemy ports, transport armies across oceans, and manage the fuel and manpower that keep your war machine running. Fog of war ensures that intelligence is as valuable as firepower.
The DEFCON system tracks global nuclear tension across 5 escalation levels. Nine nuclear-armed nations possess ICBMs, SLBMs, cruise missiles, tactical warheads, and hypersonic weapons. Launch a first strike — or hold your arsenal as the ultimate deterrent. Mutual Assured Destruction is not just a theory; it is a game mechanic.
