In Kingdom Defense you have to be in the role of the commander of the defense of the kingdom. You will have to keep defense using three towers, soldiers, traps and a variety of improvements for them. For a successful level you need to hold out under the pressure of hostile troops, not allowing him to get to the territory of the kingdom.

At each level you have to build your own strategy defense and develop it as the onset of the enemy and accumulation of stocks to improve their defensive turn.
