Void Cannon

Void Cannon is, essentially, a voidtech version of Plasma Cannon. Bigger, meanier and generally much more useful. Not to mention costly, although its exploitations is practically free (since as all voidtechs it doesn't consume energy).   Void Cannon fires a 'ball' of some sort of plasma that is not only superheated but also seems to be... slightly phased out of existence. The last part allows it to literally phase through Magnetic Shields, fully appearing only when confronted with solid matter. What's more, it is made much more cohesive that its modern version, meaning the plasma disperses much slower than it should, remaining a deadly cloud for longer.   In short - Void Cannon can literally shoot through Magnetic Shield as if it wasn't there, while piercing Particle Shield and armor with next to problems. It, however, still destabilizes on longer ranges, meaning it can be used only as most devastating SRW weapon in Galaxy (and not as standard artillery).
