The 'emperor' and 'king' achievements are impossible to get. To get a king you'll need an unbroken wall. The large flying demons go straight for the wall. So even if all your men survive those attacks with ease, you'll still lose the wall after a few waves of the flying farts (I counted at least 10 waves - and I've tried restarting it at least 30 times). No matter what you do, you can count yourself lucky if you only lose 1 wall.
The only thing that works is the green horse charge. BUt that only clears the green knight lane and only if you can rack up about 10 of those horse charges.
So either these flying demons need to be taken down a notch, the red needs to get some special that can counter them or you need to add a special that repairs the frigging walls.
Hero levels are 51, 39 and 47. Which should be freaking high enough!
Fix this so I can get my damn achievements
