Engines of war is the third expansion to the hit board game castle panic. It is not a stand-alone game and requires castle panic to play. Engines of war introduces a light economic mechanic to the world of castle panic. The engineer uses new resource cards to build catapults, ballistas, barricades, and more to better defend the castle from the growing monster threat. They charge into battle with a siege tower, war wagon, and a battering ram. And they’ve enlisted the help of a shaman, breath-taker, and goblin saboteurs. Prepare your forces! The fight just added engines of war.
