Called the Imperial Crawler by designer Christopher Aleria, this interesting take on the AT-AT would have surely been immune to Luke’s harpoon technique. Word is Aleria’s been conscripted into the Imperial military and will be cloned accordingly for future builds. The rig is remote controlled and about as off road as an AT-ATA model with huge chunky wheels could hope to be. The materials of the wheels have to be pretty damn thick/strong to support the weight of the machine.”]
