The game is based on The Hundred Years' War between the forces of England face off against the forces of France.
The game's unique style of action thrusts players into dynamic and ever-changing conflicts. Players must adjust their strategies as skirmishes evolve, and then deploy the unit best-suited to handle the challenge. At a player's command is a broad array of troops including infantry, archers, and cavalry, as well as a variety of specialized units. While each unit is comprised of autonomous soldiers, each warrior will contribute to the assigned objective.

Players assume the role of a rogue commander with a group of mercenary units who can align themselves with the French or English sides, depending on the situation.
Units include infantry, cavalry, archers, elephants, cannonries and castle siege units. The commander's reputation will affect things like the quality of troops available and the difficulty of the missions. Individual troops will also strengthen as they gain combat experience.
