The Cosmic Era stands divided between Naturals and the Coordinators they created. The ashes of Junius Seven still weigh on both sides, and every peace signed since has carried the seed of the next war. Across Earth, the Moon, and the PLANTs, new weapons are built, old grudges are inherited, and young pilots are sent out to settle what their elders could not.

Thus begins your saga within the Cosmic Era — stand with ZAFT, the Earth Alliance, or Orb, serve the Clyne Faction or Compass, or walk alone among the salvagers and mercenaries of the Debris Belt. The decisions you make will ripple through history, determining whether you break the cycle of hatred or become one more name lost to it.
