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.
Take command in Europe's greatest 18th-century war. Equip & customize regiments, manage supplies, and engage in brutal real-time battles across procedural campaigns. Resources and replacements are scarce, and keeping your best men alive may matter more than any single victory.

Master of Command is a real-time tactical strategy game set during the Seven Years' War. You take control of an army, manage its supplies, engage enemy forces, and shape your campaign through difficult choices and decisive battles. Every encounter, every piece of equipment, and every soldier lost matters.
Key Features:
Real-Time Tactical Battles: Engage in historical combat where morale, stamina, terrain, and timing determine the outcome.
Fully Customizable Regiments: Equip your troops with historical equipment and weapons that affect accuracy, stamina, morale, and more.
Real-Time Campaign: Choose a region and enter a fully real-time map with fog of war, branching encounters, and a mobile enemy presence.
Persistent Army Management: Every loss matters. Units gain experience, officers level up, and your choices carry across each region of the campaign.
150 Historical Units: Recruit from an extensive roster of 18th-century European forces, each with unique stats, roles, and visuals.
At its core, Master of Command is about the relationship between your army and the world around it. March too far and your men will starve. Rest too long and the enemy will reinforce. Your troops rely on you not just to lead them into battle, but to keep them fed, equipped, and alive long enough to reach the final objective.

Battles in Master of Command are immersive, tactical, and unforgiving.
Combat is designed to feel grounded and brutal. Troops respond to pressure, breaking when outflanked, faltering when exhausted, and rallying when supported. Morale, stamina, and formation matter as much as numbers. A well-timed charge or tactical retreat can change the course of a fight. Victory often goes not to the larger force, but to the commander who managed their troops with discipline and resolve.
Equip your regiments with historical equipment and weapons to shape their strengths and weaknesses.
Regiments aren’t expendable; they are comprised of a living group of men relying on what you’ve given them. Outfit your line infantry with rifles for long-range precision, cylindrical ramrods for faster reloads, or field musicians to steady their morale under fire. Customize their flags and uniforms to reflect your unit's identity or design something entirely unique. Supplies wear down, resources are limited, and every army ends up looking different by the time the campaign is through.

Start with a handful of worn recruits and grow into a force worth fearing.
Every army in Master of Command tells a different story. You choose which units to recruit, which officers to promote, and which regiments are worth keeping alive. Some armies are lean and elite, built around veteran grenadiers and cavalry. Others are ragged but massive, relying on sheer numbers and momentum. Officers gain experience over time, and their traits influence how your divisions fight.

Every region is different, and every march is unpredictable.
After marching your army into a region, you’ll enter a procedurally generated landscape, obscured by the fog of war and navigated in real-time. Your goal is to locate and destroy the enemy’s main encampment. What lies between you and that objective is different every time: villages, ambushes, battlefield wreckage, wounded survivors, or roaming enemy forces. Terrain affects how fast your army moves, how quickly provisions are consumed, and what kind of battlefield you'll face if attacked. Enemy armies react to your presence, sometimes pursuing, other times reinforcing, or lying in wait. No two campaigns unfold the same way, and no two armies you've led end up alike.

Every army brings its own doctrine and its own identity.
With over 150 hand-crafted units from five major European powers, Master of Command lets you build armies that feel distinct and historically grounded. Each unit has its own stats, role, and personality on the battlefield. Some reload quickly, others hit hard in melee, and a few simply refuse to break. Your roster is shaped by the army you choose and the decisions you make along the way.
Notable units include:
Prussian Grenadier Guards
Austrian Deutschmeister Fusiliers
Russian Don Cossacks
British Highland Grenadiers
French Royal Scots Fusiliers
Prussian Death's Heads Hussars
Austrian Kaiser Franz Hussars
Russian Preobrazhenskiy Life Guards
British Campbell's Highlanders
French Swiss Guards

Your army is only as strong as the men and resources you can find.
Throughout the campaign, you’ll pass through towns and villages offering a chance to recruit fresh troops, trade for supplies, or offload captured equipment. Some locations specialize in certain goods: artillery, munitions, horses, or officers, while others are picked clean or too wary to help. Prices shift based on your actions and reputation. Raiding a settlement might keep your army alive a little longer, but it’ll close doors elsewhere. Managing your resources is just as important as winning battles, and a poorly timed shortage can grind a campaign to a halt.
Strategize, survive, and lead your men to glory. Become the Master of Command.
