Hey call of duty fans nyny10 here and in this blog I'm going to show you guys a glich on the zombie mode.On the 1st map.First you must open all doors that lead you were the telapoter is and go were
the automatic gun is and let a crawler follow you and when the crawler hits you you jump and your on top of the automatic gun that zombies & Dogs can not hit you.I used this glich and I survived 89 rounds.try to do this glich because it can boost your round up like mine did.Hope this helps you.
