An epic story of war and survival set in the legendary Gundam universe! In the Universal Century year 0079, the space colony known as Side 3 proclaims independence as the Principality of Zeon and declares war on the Earth Federation. One year later, they are locked in a fierce battle for the Thunderbolt Sector, an area of space scarred by the wreckage of destroyed colonies. Into this maelstrom of destruction go two veteran Mobile Suit pilots: the deadly Zeon sniper Daryl Lorenz, and Federation ace Io Fleming. It's the beginning of a rivalry that can end only when one of them is destroyed. The lightning-streaked debris fields are about to become the stage for an epic duel where death is the only true winner.
