Mobile Suit Gundam: The Origin MSD Cucuruz Doan's Island

Caught in the crossfire is a young teen named Amuro Ray. Not willing to see innocent people die like this, Amuro crawls into the cockpit of the closest machine around him. Whether it be a tank, jeep or jet, he was going to use it to help stop this slaughter. And what he happened to slide into was another Gundam. Having never operated a machine like this, what are the chances he can do anything to repel an experienced squad of mech-piloting invaders?
