From Namco Bandai Games America:
Faithful to the Warhammer license, Warhammer: Mark of Chaos puts the focus squarely on the battlefield with a real-time combat system that gives the player unprecedented customization and control of his army. Over a year has passed since the Great War, during which the brutal Chaos armies swept across the Empire lands. Many fierce battles still rage across the Old World. Portions of the defeated Chaos armies have retreated to the distant Northern Wastes, while others have fallen to hostile groups. Among these tribes, new Champions rise up in an effort to reunite the Chaos forces, yet eventually all fail. None can match the power of their fallen leader, Asavar Kul. The united Empire and High Elf forces hunt the Chaos hordes from the Empire territories, still alert because danger lurks around them in the form of smaller enemy warbands that loot the settlements of the border lands. Now, four fully playable powerful armies--Empire, Chaos, Skaven and High Elves--as well as additional controllable races (Orcs, Dwarfs, Vampires, and Goblins), clash amidst breathtaking scenery in an epic battle for land and power.
