Blood and Gore
Creative Assembly were clearly worried that Total War: Rome 2's battles were too mild-mannered and sedate. And so, as with Shogun 2 before it, they've released the "Blood & Gore" DLC pack, which amps up the violence to its most absurd setting. Whether its worth the £2/$3 for what is essentially a superfluous graphics tweak is something you'll need to decide for yourself. All I know is that the screenshots which released alongside it are ridiculously, hilariously over-the-top.
