Element 115 (Ununpentium, or Divinium). It was discovered by the Germans during the First Earthican Civil War in Northern France. According to the radio messages in Shi No Numa and Der Riese, it is extensively used by Group 935. Element 115 is harvested from meteorites that have been found in Shi No Numa, Der Riese, Groom Lake (Area 51), Tunguska, and the Moon. One of these meteors can be seen in Shi No Numa, this was the only meteor to be found in the location. Meteor fragments can be found in Kino der Toten, Shangri-La and Origins. Said meteors are red in color, emit strange noises, and have electrical pulses flickering across their surface. Origins' meteors are green in color.
Element 115 was used to create the zombies as one of its side effects was the reanimation of dead cells. The zombies were to be used as super-soldiers by the Nazis. After creating them, the Nazis realized that they were uncontrollable and would lead to mankind's destruction. The Ray Gun, the Pack-a-Punch Machine, the Perk-a-Cola machines, and the Wunderwaffe DG-2 are all powered by Element 115, along with the teleporters. It would appear Element 115 can also control the zombies, as the Focusing Stone is a shrunken-down meteor that Richtofen claims will let him control the world.
