Scrambling everything they can, the White Base sets out with her newly formed crew of civilian recruits and refugees in her journey to survive, and unknowingly, change the course of the war. Out of desperation, citizen boy Amuro Ray accidentally finds the Federation's new arsenal—the RX-78 Gundam, and neutralized the situation. A Zeon reconnaissance team member disobeys mission orders and attacks the colony, killing most of the Federation crew and civilian in the process. However, they are closely followed by Zeon forces.
The story begins with a newly deployed Federation warship, the White Base, arriving at the secret research base located at the Side 7 colony to pick up the Federation's newest weapon. After half of all humanity perish in the conflict, the war settled into a bitter stalemate lasting over 8 months. Zeon, though smaller, has the tactical upper hand through their use of a new type of humanoid weapons called mobile suits. The conflict has directly affected every continent on earth, also nearly every space colony and lunar settlement. Story Set in a fictional universe in the Universal Century year 0079, the Principality of Zeon has declared independence from the Earth Federation, and subsequently launched a war of independence.
