"In 1999, an alien spaceship crashed onto Earth. Hidden on board were the secrets of a unique science known as Robotechnology. Databanks found in this ship were transferred to the Earth Robotech Computer Complex. In 2009, an alien search party arrived from hyper-space to reclaim their lost databank. The United Earth Government was forced into an Intergalactic war. Earth forces were able to win the first battle… But at a great cost. The planet was virtually destroyed. New population centers grew out of the ashes… It is now 2027. A second armada sent by the aliens is nearing Earth. They have come to recapture the secrets of their lost technology… And then destroy the Earth!"
