use orcs of the south...get throwing axemen before the second or third battle send two swordsmen in front on any lane and spam axemen behind them, do this for every lane you can win the whole game like this
to get the spartan thing, create two missile towers, then spam gunmen and use the remaining money on the handgun...not that that will do much the gunmen and the towers will do everything
