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. An epic battle rages following a brutal Chaos invasion, where four fully playable armies (Empire, Chaos, Skaven, and High Elves) as well as additional controllable races (Orcs, Dwarfs, Vampires, and Goblins) clash on a massive battlefield.
