Use your archers and your special weapons (pot of oil, castle mangonel, and burning logs) to defend the castle walls from the hordes of enemies attempting to destroy your keep. If your walls fall and your lord is killed, the battle is lost and the game is over. If you complete construction of the keep, the enemy will retreat and you will claim victory. Play well, and you will be awarded points. Try to accumulate as many points as possible, then submit your score to the world-wide scoreboard and compete with players from around the globe.
