Dimensions:90cm x 70cm x 20cm
Weapons: A powerful axe, with a 4kg hardox meat tenderizer for an axehead. The tenderizer's blades are diamond tipped, and it can hit an opponent and do damage when the axe springs back to its rested position, like Terrorhurtz. The axe itself is powered by a 2.2kg 750psi Co2 tank feeding gas to a 90mm bore 400mm stroke ram which pushes the axe forward, giving near 600kgs of force.

This does not compute. :P
