Nacht Der Untoten is downloadable through Call of Duty: World at War: Zombies II for the price of US$4.99/£2.99, but buying this map would make the two apps the same.
It is the same app as the original, but instead comes with Shi No Numa instead of Nacht der Untoten, saving the user US$4.99/£2.99 if they were only going to play Shi No Numa. On June 3, 2010, Call of Duty: World at War: Zombies II came out for the iPhone and iPod Touch. On June 2, Shi No Numa was released for the same price. On February 11, 2010, Verrückt became available for in-app purchase for US$4.99/£2.99.
