Castle Wars is a combat-based team game. There are two teams: the Saradominists (Players 1-4) and the Zamorakians (Players 5-8). Both teams try to infiltrate each others' castles, rescue their King, and take them back through enemy lines to their own base to claim a victory point for their team. The first team to claim 20 points is the winner.
The team bases are located on the ground level of each castle. They are protected by energy fields, so that members of the opposing teams cannot gain access to them.
Each time you wish to release the King you will require more troops.
