(adsbygoogle = window.adsbygoogle || []).push({}); First off, the glitch can only be done in the barrier in the Bowie Knife room. (At least for me)

Tutorial:

1. Make sure the glass isn't broken.

2. Get Speed Cola.

3. Shoot bottom right, rebuild and shoot top left and rebuild.

4. If done right, one plank will be sticking out of the barrier.

5. The zombies can't come out of that barrier. Seems kinda useless, but w/e it is still a glitch. Enjoy!

EDIT: Sometimes it works, sometimes it doesn't. Just gotta be lucky =D

works on every window... and btw the zombies will break the barrier after a while...

It is useless but funny. Once a whole swarm of zombies come you will be f**ked

I have had it work on several windows

nice but it's already posted and i think also with a video

its funny this haha nd yes it works on other window aswell
