Call of Duty Zombies II: Aether

After receiving his diary and notes from the Rising Sun and Der Riese facility in 1945, Dr. Edward Richtofen now knows what he must do. However, Ultimus accidentally overloaded the teleporter and sent them across time and space, which resulted in Richtofen dropping his diary before he left. 18 years later, during the height of the Cold War, they arrive in an abandoned Movie Theatre that one belonged to Group 935. To make matters worse, the Soviet Union and the American's discovered his diary and they too are in a race to control the Aether. He must move quickly to complete his grand scheme before his allies realize his plan and Americans and Soviets get to it before he does.
