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.
Dagger Directive is a tactical FPS that allows you to approach each mission in your own way. Select equipment, decide the time of day, then move methodically to complete your mission. Enjoy the modern mechanics and old school graphics as you fight across a variety of missions and environments.
You are a member of Task Force Dagger, an elite international special forces unit. Your missions take you across the globe—through frozen coasts, dense jungles, and war-torn cities. In Dagger Directive, tactical freedom is everything: pick your loadout, choose the time of day, and decide whether to strike hard and fast or move like a ghost.
Every mission is yours to shape.
Fight across three full campaigns, each set in a distinct region with its own atmosphere, enemies, and tactical challenges. Disrupt an eco-terrorist operation in the frigid Bering Sea. Battle organized crime across the volatile South Pacific. Crush an extremist uprising in Eastern Europe.
Each mission offers a different tactical sandbox, with objectives you can approach from multiple angles.
Gear up from a robust arsenal of 25+ weapons, each customizable with a wide range of attachments. Whether you're breaching doors with an underbarrel shotgun, clearing angles with suppressed SMGs, or picking off targets at extreme range, the armory has you covered. Supplement your firepower with drones, tripwires, grenades, and mines, and experiment with combinations that suit your style.
Dagger Directive blends modern game feel with grounded mechanics. Every bullet and piece of shrapnel has weight, velocity, and trajectory—simulated in real time. Adjust your scope for distance, lead moving targets, and respect the chaos of ricochets. Even grenades scatter deadly fragments that obey real physics.
This isn’t just spray and pray—it’s precision under pressure.
Each mission takes place in a large open area with multiple entry points, dense foliage, and tactical verticality. Control the environment by shooting out lights, hiding in tall grass, or stalking through shadows. Select the time of day before each op—just don’t forget your NVGs if you’re going in after dark.
The battlefield is a tool, if you know how to use it.
The Early Access version of Dagger Directive is already packed with depth and variety:
A 15-mission campaign that spans all three global theaters, offering replayability through multiple tactical approaches.
Full co-op multiplayer, so you and your squad can coordinate, flank, and execute missions together.
Over 25 weapons, dozens of attachments, and a wide variety of tactical gear—already giving you the tools to play your way.
A broad range of tactical equipment including deployable drones, anti-personnel mines, and multiple grenade types, adding layers of strategic options.
Post-launch development will expand both depth and customization:
A mission editor with full Steam Workshop support, allowing players to build and share their own operations.
An expanded tutorial system that dives deeper into advanced weapons, tools, and stealth mechanics.
A powerful Free Play Mode, where players can spawn enemies, allies, vehicles, and gear to experiment or create their own combat scenarios.
Modding support for weapons and gear, empowering the community to add entirely new content to the sandbox.
