its very easy... make level 3 missile towers making like a "wall" on the gate,, then keep making lasers level 1 around it... it worked for me, i won it very easily
LABpwner, don't be stupid, this is an strategy game -.-
You don't have to be lucky, you have to be inteligent... If it's too hard for you, maybe the problem is YOUR strategy.
5/5
Thanks!
