It is also equipped with the latest miniaturized-versions of advanced weapons - a wrist-mounted mini-gun and a wrist-mounted rocket launcher. An interactive computer has also been integrated into the helmet with an intuitive HUD (limited thought control visualises the wielder's thoughts on the screen, such as strategies). Two prototype battle suits were used by Duke and Ripcord in Paris, France. Both are presumely destroyed / badly damaged following the battle. It is unknown if they were ever mass-produced, due mostly to the expensive materials required.
