Call of Duty: WW2 will officially have an all-new Zombies mode (opens in new tab), and you know what that means: it's time for another ARG to tease hardcore fans. The game was afoot as soon as fans noticed a hidden code in the rim of this Nazi zombie's helmet.
There's a "classified" page (opens in new tab) on the official Call of Duty: WW2 website styled after an old cipher machine. Punch that code - IUFDJ BHLOP JMUBA - into the typewriter and a message appears word by word: "A NEW HORROR RISES". Then you can look through a folder that contains two documents.
The consensus from the ARG-sleuths on Reddit (opens in new tab) is that first picture of Frederick Barbarossa is a reference to Operation Barbarossa, the German invasion of the Soviet Union. The second picture is a 16th century portrait by Italian renaissance artist Raphael, which has been missing ever since the Nazis stole it from a Polish museum in 1945. It remains one of the most sought-after pieces of art to disappear in the course of the war.
One last clue: the cypher machine itself has a set of coordinates on it that correspond to Dunkirk, France, the site of a major battle in World War 2. There's also another set of numbers on one of the folders (FORM YMF 212514 12123 131) - but that code hasn't been cracked yet.
So we have references to a French town and/or the battle that happened there, a painting missing from a Polish museum, and the invasion of the Soviet Union. And we know that Call of Duty: WW2's Zombies mode is not part of the Treyarch Zombies saga depicted in games like Call of Duty: Black Ops 3 - Sledgehammer Games general manager Glen Schofield said it would tell "an entirely new story". I'm sure we won't have to wait long for the next clue to drop.
