The Story
Your are the commander of a tank on a desert moon. Aliens from Vraktu VII are attacking the base to steal it's energy. Defend the base!

How to play
Click the game after it loads to start playing.
Aim with the mouse. Click to fire a laser beam.
As soon as you get close to the left or right border, the tank will move in that direction. You can also move the tank using the Left / Right arrow keys.
The laser needs energy to operate. This energy is always regenerating at a slow rate.

Display
Weapon energy is displayed in the upper left part of the console.
Your score is displayed below the Weapons energy.
The Radar in the center is showing all enemy ships. Ships draining energy are red.
The remaining energy of the base is in the upper right part of the console. As soon as this energy reaches zero, the game is over.

Power-Ups
If you destroy the alien attack sphere (this sphere needs several hits to be destroyed) you will get one of three power-ups:
W - Weapon Energy: Your laser will refill much faster
S - Speed: Your tank will move much faster
E - Energy: This will refill the base's energy.
