Activision and Treyarch have released their new map Zombie Verruckt (Zombie Asylum) for the highly popular Call of Duty: World at War - Zombies for $4.99.  Although the price is higher than most had hoped for, this one level update includes some new game play features and will probably help maintain COD - Zombies’ lofty ranking on the App stores highest grossing list which it has held since its release.

  

Verruckt is available only as an in app purchase once you update the original $10 game.
Some of the new features are 9 new weapons, Perks-a-Cola machines that dispense upgrades like increased health and faster reloads, and electroshock defenses all of which must be activated by turning on the electricity.  Activision provides a lite version of Verruckt for you to download to wet your appetite.
