There are a lot of indie games that either die or take too many years until completion...
Its rare for us to see an indie came take off like Minecraft and thrill millions.

One of those few is Hard Reset

Hard Reset re-uses elements from our favorite action games and packs them together with stunning detailed graphics.
The icing is a pleasing physics engine that allows destruction of almost everything!
Gun through action packed and energetic as you blast through robotic minions in a Blade Runner setting.
Ugrade your weapons and armor...

And yes, it runs great in PlayOnLinux!
What else could you want?

If you have heard of Blender then you probably know that it is a free opensource 3D modelling program that also has a game engine.
Dead Cyborg is probably the most graphically beautiful game I have seen with the Blender Game engine.
Episode 1 & 2 are totally FREE and there is a Linux release!

Dead Cyborg is a first person sci-fi puzzle game. No weapons, just explore and solve puzzles.

Dead Cyborg

If you havn't played Lugaru: The Rabbit's Foot, then you havn't experienced a martial arts extravaganza!
Your character is a Rabbit with the ability to jump very high and very long distances. His speciality? Kung Fu!
Sneak up on your opponents or utilize a frontal combo attack... Jump off ledges or run up a vertical wall...

The graphics may be dated but the action is a lot of fun... wait, this isn't about Lugaru, instead I'm introducing Wolfire's new game in development:

Overgrowth

Overgrowth is based on the original Lugaru but upgraded on every aspect of the game!
High Definition textures
Bump mapping & soft shadows
Martial Arts fighting with hand-to-hand and weapons combat
Huge maps for with detailed environments
Extremely realistic A.I.
and more...

Watch their development videos to see what is already completed.

This Linux tutorial is meant to offer tips on how to install & run PC Games in Linux Mint. I cannot guarantee these steps will work in other distributions. If your game has no native Linux installation binaries, Wine is your next best bet for the game to work. I obviously cannot guarantee the game to work in Wine either.

I also recommend learning the basics of Terminal commands. I know its silly to learn commands for gaming when Windows doesn't require any command line knowledge, but since Linux is totally free and most of the basic apps are also free, its worth a little bit of your time so you can successfully install/run/diagnose your game.

Here are some commands that may help you with PC games on Linux:

Note: when a successful command is run you won't get any evidence that it ran properly in the Terminal. So if you don't get an error, it successfully did exactly what you told it to do.

Important Note:
Any time you type a command, you will need to press ENTER...
