Appropriately titled "Blood and Gore," this DLC addition focuses on improving the brutality of combat in Total War: Rome 2. New sound and particle effects have been added alongside "hundreds of gruesome animations." According to Sega, both soldiers and the ground they fight on will now become increasingly spattered with blood and pieces of former people as combat rages on.
As you'd expect, this bloody deluge earns the DLC an "M for Mature" rating. If that doesn't turn you off, you can feed your sadistic desires by purchasing the Blood and Gore DLC from Steam for $3.
