New Ships:
Tartarus class Super Capital: This is a large super capital ship that has almost as much armor as a light titan might, but due to that, it moves very slowly and has small shield generators because of the space aboard it. It can soak up damage from other ships its size and smaller and last an astoundingly long time. It is meant to be a tank, slow, lumbering, and able to take deal out great damage. It is equipped with a Starbuster cannon, and many pulse weapon batteries, as well as several types of pulse weapons. on the front of the ship there is a place for either a planet destroyer weapon or a Sun Destroyer weapon.
Stun nets: nets that are made of highly conductive metallic wire that shock and paralyze, the target caught in the net. Can be modified to have AM tech, or AAM tech on it as well.
