During the 31st century, the New Avalon Institute of Science funded an expedition to Mesozoa. There were reports of huge ore deposits which would make the world a valuable commodity. The exploration team sent to confirm the reports landed their DropShip and proceeded to explore the world via small AgroMechs. During the expedition, part of the team was attacked by a large megasaur that destroyed two of the AgroMechs and was only driven off by the concerted efforts of three other AgroMechs.
