-------------lol---DEFINITIVE STRATEGY GUIDE:
pick a race w/ a retardedly powerful unique unit (nelves/undead for example)
play only easy (>3%) maps until you can buy your unique unit. this stage its easy enough to just throw a bunch of spearmen and you'll win
with your powerful units, defend 3-4 lines in a cascading fashion - if an enemy line is too powerful, ignore it. it DOES NOT MATTER.
get the charge, use it with the unique. up to this point you should basically only have used your uniques, with spearmen support in a pinch. now pick the line with the most power in it, set the arrow to spearmen, ????, and you'll have won.
its pretty easy to understand, and i dont really know why i chose to write this
