rebellions and terrorist activities by the Eye of God, an extremist organization who claim that Earth should be the only home to mankind. Meanwhile, the UFAR also struggles to develop a colonial programme competing against rival superpowers. A UFAR colony on Mars is eventually built, with help from Japan, alongside settlements built by the US-Canadian Conglomerate, the European Union of Nations, Novaya Russia, and the Republic of Japan. With these colonies established, Mars is divided into five regions. Part Two is set 250 years after the first part, during the Space Age Epoch. The Kwan Do dynasty has been overthrown, and harsh conditions on Mars and an increasingly negative perception of the Earth governments have finally forced the Martian colonists into rebellion.

The campaign ends with the last battle for Martian independence and the installation of Khan Sun Do as the first leader of Mars.
