In this retro game inspired of Space Invaders, the goal is to survive to an alien ships invasion by eliminating all of them. Even if their intentions are peaceful!?! The (a priori) hostile spaceships go down on Earth to your position.
Destroy UFOs before they land on Earth. Try to reach more than one ship with the same rocket. You lose a life every time a UFO landing.
Be careful, you only have 3 lives!
Move the tank with mouse and use the left button to launch rockets.
