The fifth version of Cobra's H.I.S.S. series is by far the most radical and sophisticated change to the design so far. It is also fastest and sleekest of all H.I.S.S. models. This version features large triangular treads and a smaller body equipped with twin, nose-mounted machine guns, and at least four hard-points for interchangeable weapons. The entire body can be raised on hydraulic lifts, and rotate like a tank turret. Its main weakness is its expense, and assembly between the treads and the main body is a major weak-point.
