To beat the secret mission is actually quite simple. The level has 20
levels, the first 5 levels have pretty simple guys to beat, like
goblins. The next 5 levels have a few archers and a few guys with
shields. The next 5 have a few Urah-Kai, Archers, and shielded guys. And
the last 5 levels have lots of Urah-Kai archers, Urah-Kai, shielded
guys, 3 cave trolls, and 4 forest trolls.In the last and hardest level
in the secret mission, you have to beat Urah-Kai, 2 forest trolls and 1
cave troll at the same time! To do that, kill the Urah-Kai first. Then
shoot the cave troll with axes or arrows, and then to kill the other
two, go up to them( they will be in a group) and let one of them smack
and kill the other one then run circles around the remaining one and
when it try's to attack you move out of it's way and attack it , then
start running again.
