It’s the year after Colony 211: For Fifteen years, the colonies and the Earth have seen total pacifism under the guidance of former Queen, Relina Peacecraft, but the peace could last no longer. Human nature must rear its ugly head at the best of times. At a conference on Earth in the city that housed the former capital building of the Earth Sphere Alliance, Relina Peacecraft and husband, Former Gundam-Pilot Heero Yuy, were assassinated by a young man with a stolen Ares suit in a suicide attack that killed most of the participants in the blast. It was soon confirmed that the assassination was the work of a new OZ that had been working behind the scenes to gain the control of the earth’s governments. In one fell swoop, the new OZ organization took control of the Earth using public appeal, and mobile suits that had been manufactured in secret using the blue prints of OZ mobile suits that had survived the disarming period. The colonies are now nearly completely defenseless against the new oppressing force, their only armaments coming from old factories and salvaged construction Leo mobile suits. Few gundam pilots from the old war are still around now, but there is hope for the colonies. There may be few of the pilots left, but new gundams have been made by these veterans, ready for the new generation to take to the battlefield. With these new pilots come a new force led by Milliardo Peacecraft and Lucrezia Noin consisting of many older OZ suits from the bases scattered around space. But, this may not be enough. The new OZ forces have their own gundams this time around, and few have stepped up to pilot those of the Colonies. So… Where do you fit into this? Are you here to help the colonies reclaim the peace they have enjoyed, or are you here to help the new OZ control them? Whether you’re a Gundam pilot, a soldier, or a simple civilian you have a role to play in shaping the outcome of this war.
