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.

AI War II is a grand strategy/RTS hybrid against an overwhelming, inhuman enemy who has conquered the galaxy. The enemy has made only a single error: underestimating you. You must steal as much technology as you can, and take enough territory to fortify your bases and launch your attacks.

AI War 2 is a grand strategy/RTS hybrid against a galaxy that has already been conquered by rogue artificial intelligences, alien nanobots, and many other devious (and occasionally helpful) factions. Your path to victory lies in destroying the AI Overlords, which requires you to locate and acquire new fleets, superweapons, allies, mercenaries, and defensive weaponry.

Rather than trying to recapture all the territory (which will simply enrage the vast enemies enough that they slaughter you), you must capture planets with care, invest in new technologies, and strike with precision. This isn't a stealth game, but there's a definite art to knowing when and where NOT to strike.

It's also "a sequel to [Arcen's] enormo-space RTS AI War, which we called 'one of this year's finest strategy games' back in 2009" (Tom Sykes, PC Gamer)

What's New?

We still have a lot we want to add, and even more we want to polish, but the current version of AI War 2 is already vast:

• Many optional factions, each with their own goals and strategy, create a living galaxy.
  
• A new Fleets system gives you even more ships than befire, and allows you to customize your empire more than ever.
  
• A ton of map types, and with a lot of sub-options to make them even more varied.
  
• Mercenaries to hire, factions to ally with, and oodles of targets to capture or hack --with the AI or aliens.
  
• Warden and Hunter sub-fleets of the AI provide for new challenges (and sometimes opportunities) in how both you and the AI interact with each other.
  
• Polished gameplay mechanics, representing everything learned from first game’s six expansions.
  
• Trimmed fat: repetitive boring tasks have been automated or streamlined, but more options than ever have been added for you to customize things when you want to. Our goal is never to waste your time, but always have an array of interesting challenges for you to pursue at once.

What Other Stuff?

• Redesigned UI, currently going through iterations.
  
• Over 1700 lines of spoken dialogue from more than 25 actors, and more to come from the AI itself.
  
• 1.5 hours of new music added to the 4.5 hour included score from the original game.
  
• Crazy moddability, with many levers available in easily-accessible XML.
  
• Multiplayer is temporarily disabled, but still being implemented.
  
• Multithreading for modern performance, and a codebase that will not summon an elder god.

“A grand strategy RTS game that excels at both genres. The gameplay is top-notch, mechanics are in-depth, and the quality of life combined makes this a worthy successor to AI War.”
Original Curators Group

“While it has a heckuva learning curve, once you start to grok it, it turns into one of the most amazing and satisfying RTS experiences you'll ever come across.”
Space Game Junkie

“The bots are back at it again and having conquered the known galaxy, only you can stand in the way. Defrost the stasis pods and deploy your squadrons : AI War 2 is back for more!”
