Aliens have landed in the Adrian desert. You have to destroy their weapons using your hovercraft gun.

Use W/A/S/D keys or arrow keys to move the hovercraft. Click the mouse to shoot the enemy. If the rockets from the enemy guns hit your hovercraft its strength gets reduced by a certain percent. If the strength becomes zero you lose the game. The aim of the game is to destroy all the 20 alien gun ships in minimum time.
