User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-90.212.225.109-20130807225553

What odd about the zombie storyline is the worlds notice of the zombies. If zombies were in der riese which is in germany then how come their world did not know about this!

when you look at maps like five and call of the dead they start out as if their lives were normal.

Also how can technology advance after the earth was nuked, which is set in the cold war era

This leaves us with the question about how their world doesn't know about a giant robot in ww1!
