Spider Drones are insect-like robots of various sizes used as offensive/defensive units manufactured by the United Nations, and reprogrammed to work for the Mutant Alliance on the occasion they are captured. These Drones are armed with dual auto cannons firing highly explosive chemical mixed rounds, while wielding a net gun for capture. These hulking behemoths can crush HUMVEE's and other vehicles with their large claw like feet, and can cross most terrain. However, most of the joints and other components are not armored, for the sake of transportability. This leaves several weak spots on these powerful yet under-made robotic behemoths.
