Call of Duty: Modern Warfare 3 Zombies has quite a bit of DMZ DNA within its gameplay. As if the DMZ menu icon carrying over was not enough, players will find contracts and human mercenaries roaming throughout Urzikstan. The countdown timer and looming storm also carry over, ensuring that the mode feels like a hybrid between Outbreak and Warzone’s now-concluded beta mode. However, despite all the similarities, MW3 Zombies is lacking PvP combat.
