The CATMUSS system is a system of microwave emitters placed around seven of Venmere's key cities and around 22 of its key military locations. It consists of pillars that emit microwaves in between them, creating a cube around cities. It is only activated during an attack. Explosives and such that are launched at it are exploded by the microwave shield, preventing them from destroying the city inside.
