Description: In this exclusive DLC pack you will have access to the all-new Herd Mode where you need to fight for survival against endless waves of walkers. You can't afford to rest! In addition, fight off walkers in the story mode with a new arsenal of melee weapons including a survival knife, sawtoothed machete, kukri, reinforced hatchet, and advanced machete. With ammo scarce and the undead attracted to loud noises, a sharp, silent blade might just be your most trusted companion.
