I was very happy to get it.
Very nice, new units, new combat ways! or not??
Check this out.
Sell any resource you have and buy Archer Cavalry; hundreds of them. Then send them to be running up and down close to enemy walls. Do this along any side of the castle.
In some minutes, almost all of enemy troops would be killed. Then Creat some trebuchets and sword soldiers(or any other of melee troop). Destroy the walls with the war machines and send the melee to slaughter the remaining enemy fighters and leader.
I is so easy that way.
Irritating easy I should say..borying may be the right word. I hope you wont do that.

PS: the skirmish is based on only 4 maps! Hey!Give me a break...!
