Demo games
Below are demo games that were created to demonstrate Artemis functionality and give an example how to use the framework in a game.
Spaceship Warrior (latest)
This is a newer project that uses libGdx and is more current with the latest changes in Artemis, besides being a bit more fun.
StarWarrior
The StarWarrior demo game was created for Artemis and uses Slick, and is always using the latest version of Artemis.
TankZ
TankZ is an incomplete game that uses Artemis, it may not be using the latest version of Artemis.
