(adsbygoogle = window.adsbygoogle || []).push({}); Treyarch's signature Nazi zombie co-op may have been secretly stuffed into Call of Duty: Black Ops.

The popular game mode is mentioned in two separate retailer listings for the official Bradygames Black Ops guide - one on GameStop and the other on Play-Asia.

Both list "Nazi zombie coverage" as one of the product's features.

Neither Activision or Bradygames were available for comment, but we'll let you know when they are.
