Treyarch just tweeted this picture saying, “The calm has ended – they are beginning to return.” Some say it looks like Nacht Der Untoten. However, looking at the power lines and the lamp, I disagree. Treyarch also said “Are they teasers or clues? Both? Neither? Ahhh, the beauty of Zombies!!” So what do you think this is? A teaser or a clue? Or both!?
