Superweapons were weapons that exceeded typical military technology. Examples of this were destroying planets.
Definition and Nature Edit
A superweapon is a device of varying size and type that had abilities beyond typical military technology. These were more than typical WMDs which could destroy cities and perhaps even entire countries and continents, a superweapon could devastate an entire planet.
Yet, this was not the only type of superweapon. Some weapons created, they could create and arm an entire army's worth of equipment, weapons and technology.
Regardless, superweapons are meant to change the very nature of the battlefield, erasing it, flooding it with troops/weapons etc.
