Well it will attack infantry all the time. What you did was give it a preferred target. Look at the weapon ini for a unit that does not fire at certain units. Prob is EVERYTHING I can think of fires at infantry units except maybe scorpion missle.
Thanx Capt Pickles, so I can also target particle units. Good to know. Are there more options like; AntiInfantry or AntiVehicle?
I haven't seen AntiInfantry or Antivehicle with what i've been working on, they may exist and i haven't come across them. Once i get this base defense problem ironed out i'll try them.
