Honestly I think it`s no new perk. I think it`s a machine like PaP, which allows you to "mule" (mule=hybrid) weapons, to make 1 gun out 2. Maybe only for Wonderweapons, maybe for all Weapons. When I saw this gun:
I thought.. Looks like two weapons put together. Raygun and.. i dont know, but the red marked part kinda looks like a Raygun. Another hint is maybe: They invented PaP in the last WaW Zombie Map: Der Riese, now it`s the last BO Zombie Map: Moon. I think its time for something big.. Could be a gun mule machine, to give the player more opportunities. What do you guys think?
