Let’s us open this by saying that at this point this is purely in the rumor category. This one is eerily familiar to what happened a week before the Call of Duty: Black Ops Escalation DLC was announced. With “Escalation” it was due to a leaked promo flier from European retailer GAME, this time around it could be a GameStop flyer that outs the latest DLC. A recent image of a GameStop flyer has been leaked and appears to reveal the new Call Of Duty: Black Ops DLC as “Retaliation”. According to the flyer reveals 5 brand new maps including Hangar 18, Silo, Hazard, Drive-In and an unnamed Zombie mode map. If this pans out and the promo material is already printed then we should be getting the official reveal very soon.
