The Horned Rat expansion for Chaos in the Old World introduces a fifth player to the race toward corruption. With beautifully sculpted playing pieces, all-new powers, and an array of exciting upgrades, the fearsome Skaven stand ready to scurry across the face of the Old World. Players of the existing Ruinous Powers can meet the foul vermin head on with a host of new gameplay options, including alternate upgrade and Chaos cards. Meanwhile, veterans will find engaging challenges with new expert-level Old World cards and gameplay variants. Prepare to join the battle for dominance. Launch date: June 2011.
