The Anarchy is the name given to the civil war over the succession to the throne of Henry I Beauclerc, King of England and Duke of Normandy, from 1135 to 1154. This war opposed Stephen of Blois and the Empress Matilda, wife of Geoffrey Plantagenet. Numerous castle sieges took place during this period, so this was the perfect opportunity to update all the siege rules of the various games of the Game: Cry Havoc System. The tactical game includes various siege engines including a new, bigger battering ram that is more realistic than the one that was included with Siege.
