The Aborigines are angry that the British used their land to house their criminals. They built a giant hang glider and are destroying all the criminals with blow-darts. The criminal will appear at the bottom of the screen above the score. The player controls the hang glider and manages to hit the criminal 25 times to move on to the next level. If the criminal hits the hang glider 5 times, the player loses and the game start over.
