The AHRO (Alien-Humane-Rights-Organization) has aproved the race of Locustums for enslavement in the deep coal mines. They are reasoned to be largly mechanical with few organic parts. They are very resistant to explosions and can survive off of coal if trapped. They are also able to regenerate their parts though not as effectivly on a coal only diet. These somewhat slow but steady plodders seem to relish there position in the mining operation according to the review panel at AHRO. To move the walker forward alternate between the brake and pulling pitch lever down. Note: dont expect the walker to regenerate out in the open they are quite modest for such an unfeeling race---noted in the AHRO files.
