those invisible mofos freakin break you... i had no emps cuz i had no money and i couldnt see them so by the time i found them without the emp i had 41347 of the little suicide ones own me :(
holy crap, on battle 8 i was just about to win, the castle had 250 health left, and all of a sudden the enemy spawned 52 guys and like 10 catapults and pushed back my wave of 9 paladins and moved all the way across the map before my arrows could even take out more than a few... lol
