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.

A frantic new 2d shoot 'em up with huge levels and truly massive enemy ships. Mixing game styles from Uridium, Xenon 2, Nemesis and R-Type.

Iridium is retro styled 2D shoot 'em up, taking inspiration from: Uridium, Xenon 2 Mega Blast, Nemesis/Gradius and R-Type. Each game in its own right is considered a classic by many people and offered some very unique features including massive ships, upgrade shops, in-level upgrades and a multitude of weapons.

The game is a horizontal shoot 'em up where the player is allowed free movement within each level. Unlike traditional 2D shoot 'em up games were the screen scrolls at a fixed rate the player can change speed and turn around in a similar manner to Uridium. The maps can be very large and often have a great number of enemy ships and other objects on screen at one time. Icons representing enemies and other important structures that are not on screen yet are shown around the edges of the screen. This includes a flashing star guide which shows where the player needs to be going in order to progress along each level.

At the beginning of each game the player is given some basic weaponry as well as the ability to upgrade it during the level. The weapon and system upgrades which are currently available to the player are shown along the bottom of the screen along with how many upgrade credits the player has collected (similar to R-Type). Each upgrade will also show what level they are at by displaying a small progress bar in the upper right of their graphic. Later in the game the available upgrades can be changed. (NB: All references to shop, credits or currency is virtual, no additional spending is required for this game).

There are 6 levels in total, each having its own custom graphical theme and being made up of four large stages. In total there are 24 maps to discover and explore. Each stage features 6 different enemy ship types as well as multiple larger multi-part ships. Some of the ships and ground structures release coins, health pickups or even weapon upgrade credits. A check point system has been implemented to help the player progress and avoid repeating large sections of a stage. As the player progresses through a stage the enemy structures and attack patterns are dynamically changed.

Once a level is completed there is access to a shop where the players ship can be upgraded. Many different upgrades become available as the game advances, these can be purchased using the in-game coins collected from destroyed enemies and structures from the previous levels. The current game can also be saved from within the shop giving the ability to carry on again.
