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.

Inspired by classic Commodore 64 and arcade games, Promethium is a hard-as-nails retro inspired side-scrolling shoot-em-up that takes place over numerous levels that get harder and harder. If you’re after a nice calm casual game this isn’t it!

The Promethium armada is headed to Earth, leaving a toxic trail of destruction in its wake. Commander Braybrook, it is your mission to take up the experimental deep space fighter and stop the armada before it reaches us - YOU ARE OUR ONLY HOPE!

INSPIRED BY C64 AND ARCADE CLASSICS

Inspired by classic Commodore 64 and arcade games, Promethium is a hard-as-nails retro inspired side-scrolling shoot-em-up that takes place over numerous levels that get harder and harder. If you’re after a nice calm casual game, this isn’t it!

Gameplay

Fly left and right over the Promethium armada ships. They have shield generators protecting them. Hover over a shield generator to hack and disable it. Once all the shield generators are disabled a self destruct code will be sent to the armada ship causing it to explode. Be careful though, the armada ships are guarded by a fleet of fighters!

Power-ups

Destroy enemy ships and collect the power pods they drop. These power pods are like cash, they allow you to buy power-ups.



The available power-ups are displayed at the bottom of the screen. The power-up you can buy is highlighted in orange. Every time you collect a power pod the next power-up becomes available to you. Some power-ups are single use, some are multiple and some are timed. Experiment to find your perfect combination.

Controls

Promethium can be played on a joypad or if you're really brave and have the reflexes of a Ninja Cat then you can use a keyboard. I'd really recommend a Joypad though, this game is tough enough as it is.

Use any analog stick or the d-pad to control the experimental fighter, or in keyboard mode use WSAD or cursor keys to fly.

You can fire using any of the triggers, bumpers or the 'B' button on Xbox 360 or Xbox One controllers and the 'O' button on the Dualshock controller. If you are in keyboard mode you can press the space bar to fire.

You can buy the current power-up by pressing the 'A' button on Xbox 360 or Xbox One controllers and the 'X' button on the Dualshock controller. If you are playing using a keyboard then any key other than WSAD, Space or the cursor keys will allow you to buy the current power-up - I'd suggest the return key is a handy one.

“Depression can be exceedingly hard to manage, bombarding those affected with a barrage of challenges that – left unchecked – can tear them apart. That's the core concept behind UK indie developer Byron Atkinson-Jones' upcoming shooter Promethium.”
Kotaku

“Side-scrolling shmup with some sweet cel-shaded art and a nice line in really gigantic-feeling spaceships in the background, in a way that reminds me faintly of the Red Dwarf intro credits. It’s fairly straightforward, being unashamedly a C64-inspired shmup rather than a wild and weird J-shmup-inspired piece, but that means it can get on with cranking up the difficulty and being a pure test of skill rather than bamboozling you with mechanics. Speaking as someone who only has occasional relationships with shmups and as such isn’t particularly motivated by difficulty, I did find it perhaps a little samey level-to-level, but it’s tight and I do love the model spaceship-like look.”
