The unity are a virus, a virus which infects anything robotic. Once infected it begins to turn the machine into a weapon for war... Its only purpose is to serve its masters....
Ima start with a boss ^_^
Purification Combat Walker A.I.
This thing is HUGE. Its main weapon is this MASSIVE partical cannon which will devastate anything its aimed at. It is dotted in numerous amounts of turrets which will prevent you from jumping onto it to try hijacking it. At the back, it has panels which flip revealing motar launchers which will devastate anyone standing still. At the very front, in the picture, you can see many missiles rdy...Its armor is also near impendrable to small arms fire and energy weapons. Most things will simpley bounce off its armor (note turrets are killable, but hide underneath panels within the armor). Don't worry fenix, this thing is killable! Zero knows how ^_^
Unity Hivemind
These robotic nodes are usually on very important ships or commanding a.i.s. Hiveminds are the unity's counter to Psionoic powers which if you use psionc powers within its radius, you'll be dealing youself more damage than you are to anything else.
