This is a war strategy game called Medieval Battle 2P. Set up your strong troops and plan your battle to win the war.
You have to plan where to put your units in each of the 12 levels that make up the game. A swordsman in the front and an arch in the back is the best way to do this. There are a limited number of fighters that you can buy with coins, so really think about which ones you want to get.
Have fun and good luck!
