The biggest, ugliest and loudest orcs always get the best stuff. In this case, duel Power Punchers.
These massive fists are powered by a micro-nuclear pack, contained in the wielder's armour, which provides extra kinetic energy to "punch everythin' in the face!"
SPLAT!
Elite troops for your Space Orcs. Great at bodyguards for the Warlord, or just to smash some faces in during the close combat phase.
