In Asteroid Defender! you take on the role of an elite pilot who has been recruited to the Earth Defense Force. Your mission: protect our world. Patrol the stars with the X-33 fighter ship as you blast endless waves of asteroids from the sky before they can hit Earth in this fast paced space shooter. Earn upgrades along the way, maintain your defenses, and undertake various side missions. Do you have what it takes to protect our world?
Powered by four separate pylons, the Earth shield provides a secondary layer of defense for any asteroids that slip past your guard. You must seek out and collect power cells during your patrol of the stars. As you travel between each pylon, keep a close watch over the power levels, making sure to install power cells into any failing pylon.
If all four pylons fail then the Earth defense shield will power down. Without the shield Earth can only survive several asteroid impacts before it is destroyed!
