The attackers have to hurry because the defenders will soon be reinforced by its own cavalry. Returning to save the day.
You can also play two alternate game modes of Kill the King in addition to the normal mode. The first is a regular battle between the two players armies outside the castle walls. The second is a big version of the normal mode where you combine two game boards. One player defends the combined castle of the two game boards, while two players try to attack the castle on one side each.
