User blog comment:Argorrath/Treyarch posts a message of zombies; possibly hinting to a DLC 4/@comment-356904-20130801094138/@comment-67.87.55.100-20130804055054

Treyarch likes to troll, but they wouldn't do that, They wouldn't make letters claerly written by a Jap, Russian, American, and Doctor involved with 115 and not have them be the Fab Four, that would just be cruel
