One of the more interesting aspects of the upcoming Total War: Warhammer, is that each of the different armies and races have their own campaign styles. If you're the Empire, order and taxation are your friends, but things are very different elsewhere. Orks thrive on war and need to keep fighting regularly or they'll brawl with each other, whereas Chaos, rely more on a blend of brutal strength and creeping, evil influence to expand.
That's what we've gotten a look at in the latest Total War: Warhammer walkthrough video, showing how the Chaos campaign works, how the heroes can influence the world around them, tech trees, battles and spellcasting.
One unique aspect of the Chaos campaign is that monetarily it's not the most stable. By having to continue its momentum while maintaining more fixed installations and fortresses than the Orks, it needs a lot of cash and that is quickly eaten up by its powerful units.
Get ready to do a lot of looting.
Burning your enemy's settlements to the ground though will grant you additional population and advancement through the tech tree.
Chaos will be the right army for those that love to hit hard, but don't mind a bit more micro-management to optimise your forces.
