Members - Galactic Missile Defense

The year is 2015 and humanity has made a big step, Pry rover has successfully landed on Mars, roaming on the Red Planet's desert for evidence of life form. Scientists didn't like what the mobile laboratory found, aliens got angry because of an unfortunate moment the ultra robot had with them. It is up to you to save the world from their horrifying threat. Galactic Missile Defense is a shooter/tower defense game where you are in charge of 3 secret technologically-advanced bases that are the last hope to save Earth! Of course you are not alone, your bases can be upgraded to deadly machineguns or bring up the heat using their ultra-charged laser beams. So, what do you say General, are you the right one for this challenge or Earth as we know it will end today?
