We figured out a way to keep the zombies out and they never come in the house so you can get to what ever round you like. Its very simple and we will release how to do it when we get some free time. in the mean while please subscribe and we will keep you updated. Thanks
1. You did not find this... I posted a video like a month or so ago n I wasn't the first to find it I was the first to make a video though.
2. If the tutorial says anything apart from "survive untill you get into round 30+" then you're full of it.
3. There is nothing special to trigger this as it is simply Treyarch's **** up in programming that case it so no one should be able to claim this as there own.
Hmm.. I wonder why noone posts a TuT?
It's because its a simple console error, where at about round 20 - 30 the zombies will stop continueing to get in through certain windows.
