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.

3D visualizer and simulator of the Dongfeng-41 (DF-41) road-mobile intercontinental ballistic missile.

This is a free 3D visualizer and simulator of the Dongfeng-41 (DF-41) road-mobile intercontinental ballistic missile. The DF-41 launcher itself is fully drive-able with mechanics to launch the nuclear warhead in-game.

This is a small-map open-world sandbox setting where the user is located in undisclosed location in the deserts of China and is given the task to roam around in first-person walking mode and/or drive around in driving mode to any arbitrary location reachable by the mobile launcher on wheels and then given the latitude to launch and release the nuclear missile upon successful nuclear code authentication process.

After initial release, later on there are planned further enhancements including implementation of volumetric VFX for launch effects, more secure authentication mechanisms prior to nuclear launch; an underground bunker, tunnel and command center system; and the ability to follow/track the intercontinental nuclear missile in camera-view after it has launched in order to see it traverse across vast distances on planetary scales.

*Nvidia Ansel is enabled to allow users with Nvidia GPU to perform "ALT + F2" while in-game in order to take more cinematic shots in a digital-photography type of mode.



### Quick Start ###:

The game loads directly into first-person mode, enabling the gamer to walk around using WASD on the keyboard and mouse cursor to turn and to look up and down. You may explore the entire map. To enter the DF-41 mobile launcher vehicle you should walk to the front cabin on the left-hand driver-side and approach very closely to the front set of doors and then hit "E" key to Enter the vehicle. Once in vehicle the drive mode takes over and the WASD keys now control the driving mechanics and the mouse cursor can be used to pan the camera around the DF-41 truck. To exit the vehicle in drive mode simply press "E" again to exit back to first-person walking mode.

To raise the missile tubes in preparation for launch, the DF-41 must already be at a full stop (spacebar for brakes) and then press "R" to raise the missile tube. Once the missile tube is raised vertically at 90 degrees upright, you may then press the "T" key to start the countdown to launch. At any time during this entire process you may choose to press the "J" key to eject the missile tube dome. If you forget to eject the dome prior to missile launch it will automatically jettison and eject before final countdown begins.

Although not required to play the game, there will be optionally the ability for the user to emulate a pseudo authentication process prior to nuclear launch via means of using a free standalone DF-41 Authenticator app (Android and later iOS) in conjunction with the DF-41 Simulator. More details on this can be found in the user manual.

*** A more comprehensive PDF user manual will be followed up and released shortly ***

During gameplay you can press the "U" key to make hidden the missile tube dome to directly expose the nuclear missile inside the tube, and pressing U once more time will hide the missile cap and expose the individual MIRVs (of which there are up to 10 configured on the DF-41) inside the missile. Pressing U a third time will cycle it back to original configuration of displaying everything and un-hiding all.
