Based on the tabletop fantasy wargame created by Games Workshop Ltd., Warhammer: Mark of Chaos is a real-time strategy title that eschews resource management and base building in favor of battlefield tactics. Warhammer fans will command one of four playable armies (Empire, Chaos, Skaven, and High Elves) as they lead their regiments into battle amidst fully destructible, randomly generated terrain. Tribes of orcs, goblins, dwarves, and vampires are also available to hire as mercenaries, each offering varying strengths and weaknesses in combat.

The campaign mode offers a progressively challenging series of battles as part of an epic war, with both hero and champion units growing in experience and learning new abilities and leadership skills over time. Yet instead of following a linear format, the game has players deciding which battles to engage in from an overhead map. This turn-based phase gives players time to develop their strategy and manage their armies, from hiring new soldiers to selecting which regiments to deploy. Like the tabletop game, armies can be customized with a choice of war banners, paint schemes, and even body parts. ~ Scott Alan Marriott, All Game Guide
