Call Of Duty Zombies:Richtofen

Chapter4: Richtofens Test subjects

Richtofen had pretty much finished with the testing on the zombies so he began his tests on actual people
This consists of
A drunk Russian (Nikolai)
A Japanese general (Taeko)
And a Mexican (unkown)
After many months of testing on the  Mexican he had died and Richtofen had to find a new subject and he did
An American (Tank Dempsey)
Little did they know they was being brain washed by Richtofen.
He used element 115 and this proved Richtofen s theory about element 115 erasing memories and you wouldn't even tho it was happening.
