Remember when the escalation map pack picture was leaked by British retailer GAME? Well it looks like it happened again, this time in America and from one of the biggest game retailers, GameStop. 5 more maps being added, 4 for matchmaking and 1 zombie map. The 4 Multiplayer Maps are called Hangar 18, Hazard, Drive-In and Silo. The flyer looks pretty legit and just like with the escalation map pack, this very well could be legit. There’s no name or date set, and we hope to hear more about this new map pack pretty soon!
