In Cosmic Defender you have to defend your planet from an alien attack. Guide your aircraft backwards and forwards to destroy the invading aliens and save the people from being abducted. Shoot the Alien Ships and they will drop the humans they are trying to abduct. If the people fall from a great height, they will die. Save them by catching them mid-air and placing them back on the ground for maximum points. If you are going to crash, quickly press 'D' and teleport to a different area.
