The All-Terrain Ground Assault (ATGA) Crawler was another Star Wars set created for a LEGO contest several years ago. Back in the day, Brickster_Tim put a lot of work into this one. It has slightly poseable, but strong, legs, a giant laser, a spinning turret with firing missiles, a globular prison for captured enemies, and small detachable ships.
