Unlimited tower moving!
It is the year 2250 and planet earth has developed nuclear space ships that are capable of traveling millions of miles. While on mars, we discover a secret pass, leading to a huge underground city, full of alien life. The humans that discovered it were immediately killed. As a result, the aliens of mars plan to destroy the earth so the secret is kept. The national defense of all countries have surrendered, and it is up to a last ditch effort from the United Nations to stop the ships in flight.
