Step aside Call of Duty 4 -- it"s the zombie"s turn to shine. Activision has announced that the latest Call of Duty: World at War map pack has hit more than one million downloads, a mere week after the DLC first became available.

The numbers come from the period spanning June 11 to the 14th, which would mean that World at War"s second map pack only had a week to hit those numbers.

The new maps include Banzai, Corrosion and Sub Pens, with the popular Zombies mode getting an update via Shi No Numa. The previous map pack featured battles in a fire-bombed Berlin as well as the appearance of a zombie asylum.
