The Crusade expansion introduces many new game concepts as well: Impetuous Pursuit, Feigned Flight, Shower Shooting, and Charging Cavalry ability to pass through friendly stationary infantry units, all of which add historical depth and flavor. Still many game mechanics remain constant, like the deck of Medieval Command cards that drive movement while creating a “fog of war” and the battle dice that will resolve combat quickly and efficiently. There are also new and updated Inspired Actions for both the Crusader and Mid-Eastern armies.
