In 14th century Europe the king of England lays claim to the French throne and thus begins the hundred year war. Take control of Jeanne la Pucelle "Joan of Arc" and her fellow commanders Jean de Nouillonpont, Etienne de Vignolles and Duke of Alencon as they fight the English to recapture France and keep King Edward III from taking the throne.

Joan of Arc can be described as an action role-playing game with some real-time strategy elements. Directly control Joan of Arc or one of the other commanders on missions that relive some of Joan of Arc's more important years in the war. This is the RPG side where you will combat the enemies one on one with some help from a few troops you pick up. Use combos (a series of mouse clicks like AA, AB, AAB etc.) to perform powerful attacks. Gain experience to level up and receive points to increase your stats as well as combo points to enhance your combos or learn new ones. You can switch between the four main characters anytime if they are in your group as they will gain experience and grow stronger also.

As you complete more missions and become more powerful you will be able to control armies to lay siege to castles. Switch to RTS mode (an overhead isometric view) and rally your troops to fight for you then switch back to RPG mode (a third person mode for melee and first person mode for range attacks) and fight in the heart of the battle. Assign troops to each of the four main commanders and switch back and forth between them during the battle. Build siege weapons to conquer castles to once again bring France back under control from England.
