Ok, I've just started the game. Had to do a den defence, but lost. Soon as i restart, i take back the den, but my awareness is maxed, so i instantly have to do a den defence. I lose, take back the den, but my awareness is maxed so I instantly have to do the den defence. Ad nauseum. I use riflemen everywhere, but not even close. WTF? I don't have the caltrop or other bomb option aside from the cannon? How the hell do I defeat that greek siege engine and make this hell stop???
