About Asteroid Defender!
Asteroid Defender! puts you in the role of an elite pilot recruited by the Earth Defense Force. You patrol space in an X-33 fighter ship, destroying waves of asteroids before they hit Earth, while earning upgrades, maintaining defenses and taking on side missions.
Keep the shield online
The Earth defense shield is powered by four pylons and protects the planet from asteroids that get past you. During your patrols, you collect power cells and install them in any failing pylon as you travel between them. If all four pylons fail, the shield powers down, leaving Earth able to survive only several asteroid impacts before it is destroyed.
