Good and Bad Aliens are falling to Earth. Can you "Save the Earth" ? Touch and kill the BAD Aliens before they hit the Earth to save us from destruction. Touch a GOOD Alien and it will turn into a MUTANT Alien which can be a big problem in Outer Space. You must kill the Mutant before you can continue to save the Earth from the BAD Aliens. If the Bad Aliens become too much to handle use a Peace Bomb to clear the screen of BAD Aliens. Use these sparingly when you need them the most. Clear level and move on to the next. High scorers can receive rewards. So are you ready to save the Earth from the Peace Invaders?
