(adsbygoogle = window.adsbygoogle || []).push({}); There is a glitch where all the zombies run to the bottom and all gather by the box. We had a friend who had to go and he stayed in the glitch for us. Me and my friend both went down and he was the only one alive. My question is would the zombies have dies off by them selves with out anyone playing? They weren't going after him and he was the only one alive. It was lvl 21 and we must have waited 2 hrs :/ and idea?
