Bladestorm: The Hundred Years’ War puts gamers in the role of a rogue commander and gives them direct control of mercenary units in fierce clashes with English and French forces.
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 such as elephant units, cannoniers, and castle siege specialists. While each unit is comprised of autonomous soldiers, each warrior will contribute to the assigned objective.

Bladestorm utilizes a "Free Mission" system that allows players to align their forces with either the French or English on a battle-by-battle basis. This unparalleled freedom allows players to take on different assignments, or simply experience a given battle from an opposing side.
