Royal Offense

Everywhere there is monster all around.  One day, the king call all his knights to drive off the monsters.  You are the head of the knight and you want to prove your team to the kin. You need to call in your knights to defend the kingdom against the monsters.    The game is like a defense since you just need to send your knights to kill the monsters that are attacking.  Each monster kill will earn you money and the money that you earn can be used to hire more knights to defend the kingdom.
