It appears my current exile from the motherland may prove tortuitous. I have received orders to undertake a vital mission in Northern France.

Reports from the area suggest the Kaiser’s War Machine may be gearing up to unleash something unlike anything we have seen before.

UPDATE 2: Treyarch has posted a new zombies image with the date of November 19th, 1917.

Its seems beyond a doubt that Fritz is up to no good. Air reconnaissance suggests prototype armored weaponry is being tested in Northern France. Scuttlebutt reads like the ramblings of a mad man; strange lights in the sky… a mysterious plague… even giant metal men.

Ill be at the site within the week to learn the truth with my own eyes.

UPDATE: A new entry image with the date of October 6th, 1917 was added.

The emperor grows concerned that the barbariant drive for mechanig ation may soon yield weapons more deadly than anything the world has ever known.

Here’s what the first entry post says:

September 22 1917

Previous rumors have suggested that DLC 4 for Black Ops 2 may launch on August 27th, however no official information from Activision has been released at this time.
