In this game, it is your job to defend the castle from the different types of enemy units for as long as possible. Use your archers and special weapons to destroy the enemy. Your goal is to complete construction of the castle's keep before the walls fall and your Lord is killed. If the castle walls fall to the enemy, it will be up to your Lord to defeat the enemy on his own. If your workers complete the keep before your Lord is killed, you win the level. If your Lord is killed before the keep is complete, the game is over.
