By 1939, two members of the group named Richtofen and Schuster had successfully teleported a walnut. The discovery of Element 115 led to extreme advances in military technology spearheaded by Maxis, and would eventually lead to the creation of the zombies themselves when the group began experimenting with reviving the dead.
Maxis formed the group after discovering Element 115 – also known as Moscovium or Divinium – in 1931. In the story, the origins of the Ray Gun on Earth can be traced back to Doctor Ludvig Maxis, a doctor who formed a research group known as Group 935. Although the events of the Call of Duty zombie games take place in their own timeline, that timeline is relatively consistent and has some unique aspects of its backstory.
