Defend your space station from the attacking alien horde.
You don't have any weapons of your own, but what you do have is a super charged deflector array that can repel enemy missiles. Your objective is to bounce alien missiles back to the alien scum and blow them out of the sky.
Timing is the key to successfully deflecting incoming missiles - the deflector cannot protect the whole station at once and loses power quickly needing to be recharged.
Watch out for power ups, they can mean the difference between surviving a level and being wiped out!
