Im suprised nobody knows the one im about to say...
this one can be done anywhere but its best to do it in front of mystery box because you can keep getting weapons.
-One person jumps repeatedly in place
-another crawls under his feet while he jumps
and stands up to where he is inside of him 0.0 :pedo:
-Now sometimes it can get hard to shoot because it thinks your shooting your own guy but you still can.
-Do not use ray gun the zombies run inside and around you so it hurts you and pushes you out of place.
-You can spin 360 degrees just dont move.
This thread is old but i mean a still working Nacht der untoten glitch....its worth it.
