- Edward Richtofen in Call of the Dead

Harvey Yena is an American member of Group 935. He is mentioned by Edward Richtofen in a radio message in the Zombies map 'Call of the Dead'. It is likely that he created the Hyena Infra-Dead as it seems to be a reference to his name being H. Yena. He wrote the following line on the chalk boards in Der Riese: "HYENA, Edward Richtofen I know it was you, why won't it work anymore."
