Aliens are attacking! They're launching missiles and sending UFOs to blast the moon base to tiny little bits and it's up to you to stop them by shooting down their missiles and saucers. Can you rack up mega points and blow the aliens back to their planet.
Aim your missiles with the mouse and Left-Click to launch them. For a bigger blast, hold down the Space Bar to fire a Mega Scud missile! The more of your bases you keep safe the more points you earn and the more ammo you get for more alien blasting!
