Im ATVI_Mikey, and im with Activision customer support. We are currently having a contest to give away a few of our Call of the Dead posters. To enter you have to take one of the Twitter profile picture of one or all of the Activision Social Media support team and photoshop it into the best zombie or zombie scene you can. The top entries will be posted on our Facebook Activision Assist support page for people to vote on. The 3 entries with the most votes will be given posters, and the entry with the most votes will receive a Call of the Dead poster and a code to unlock the classic Zombies maps on the console of their choice (PS3, Xbox 360).
