The Universal Century began with mankind moving its burgeoning population into outer space. The year is UC0079. The cluster of colonies furthest from the Earth, Side 3, proclaim themselves the Principality of Zeon and launch a war of independence against the Earth Federation. Now, it is nearly one year since the war broke out. In the “Thunderbolt sector”, a reef section of space where a large quantity of wreckage from battleships and destroyed space colonies from the war lies, a violent battle plays out as the Earth Federation Forces set their sights on recapturing the Zeon-controled sector.
