One of the most common technologies of the setting are anti-gravity devices that allow planetary vehicles, starfighters, and other machines to fly. The largest vehicles are corvette class starships used as scouts, couriers, and landing craft. The main unit of the armies of Renegade Legion are grav tanks, grav APC's for transporting infantry, and Bounce Infantry that use grav belts to enable them to jump long distances even while fully loaded. Gravity control is even used for nuclear devices in the form of a device known as a HELL bomb. The bomb instantaneously increases the local gravity to such an extent that nearby matter undergoes nuclear fusion and explodes.
