The Defenders have sixteen units: four Knights, four Archers, four Cannons, and four Boiling Oil Cauldrons. The Attackers are assaulting with twenty-eight units: eight Knights, four Archers, four Cannons, four Sappers, four Battering Rams, and four Siege Towers. The Attackers must breach the castle walls to take the fight to the Defenders. A six-sided die is used to resolve combat, and to determine how many units a player may move.
