Technology & Combat Characteristics

This powerful long-range beam cannon was developed by the Principality of Zeon, and used by the mobile suits piloted by snipers from the Living Dead Division. It is powered by three onboard large generators, and does not draw power from the controlling mobile suit. The gun's barrel will wear out with use and needs to be replaced after firing a certain number of beam shots.

History

The Big Gun was operated by mobile suits of the Principality of Zeon's Living Dead Division in the Thunderbolt Sector, hidden among the debris of the surrounding Side 4 colony to pick off enemy forces of the Moore Brotherhood. They destroyed multiple of the Brotherhood's RGM-79 GM (Thunderbolt Ver.) units.

After the war, a Big Gun was used on Earth by Daryl Lorenz piloting the prototype of the Psycho Zaku Mk-II against the Pegasus-class assault carrier Spartan.
