I wanna no if its new or old.

Open the first stairs in the main room and get someone to grenade themselves where the old grenade glitch was, then revive him before he dies..

Now this will cause the zombies to go to the other stairs at the HELP room.

This is for Nacht Der Untoten.
MAKE SURE HE STAYS THERE

for some reason i doubt this working,most of the glitches only work if someone dies in a specified spot and IS NOT revived,have you tried this yourself?

Hmm shouldn't you let him die?

No, revive him and he'll be stuck inside the wall, like a DJ

Tried this myself.
