Alien Break In © 1983 Romik.
The citizens of Earth have fled before the oncoming Zargon fleet. You have been left to guard the Earth's supply of uranium... Suddenly the sky above you is filled by the enemy fleet... Things are worse than expected...
The mothership is laying pods that hatch on landing, or split into two if shot. Other ships are peeling off from the main fleet, and diving towards the holes made in the defences. The successful ones mutate into motherships which are indestructible.
Once the majority have mutated, they commence landing procedures.
You may make holes in your own defences to trap the hatched out pods. You can only do this five times.
