Featuring a full new single player story with all new gameplay and multiplayer modes – along with new weapons, zombie animals , mythical creatures and even a brand new secret location – the Undead Nightmare Pack will be available very soon for download via Playstation Network and Xbox Live (800 Microsoft Points).
