Call of Duty Zombies: Reason for Zombies

The entirety of Call of Duty Zombies is all based on element 115 or Ununpentium which is real. In the game it is used to reanimate dead body cells, thus, creating zombies. This element was found in meteorites and harvested by the Nazi's to make super soldiers, but they went out of control and zombies were made. Element 115 makes all the magical devices in the game work. It is used to control the zombies, weapons like the ray gun, teleporters, and machines that make you faster and stronger.
