Official Episode 1

Welcome to the world of MARS, an outpost located on Mars.
In 2120, while developing Mars as a suitable environment for humans to live in to migrate
from Earth to Mars, Earthlings were attacked by 'Irregulars', a race from the Magellanic Galaxy.

In response, the Earth Defense Command dispatched the most elite pilots and the
cutting-edge robots they control to Mars to restore Mars, the second home of earth people,  
from the irregular.

As a pilot of a state-of-the-art robot, gamers must defend Mars from the irregulars

so that Earthlings can successfully migrate to Mars.
