When it comes to powerful weapons, the first thing you might think of is the Ur-Quan Plasma Fusion Gun. This weapon module, the Hellbore Cannon, is just as powerful. It is unclear whether the Melnorme A.K.A. the Mael-Num developed this weapon or if it is of Precursor origin. No matter, it is the most powerful weapon module available for the Captain´s Precursor Flagship. It can be made at a cost of 6000 RU. Be warned, however, that it takes a massive amount of energy to fire, and without enough Combat Dynamos or Shiva Furnaces, the SIS will be left defenseless while it waits for enough energy to recharge.
