For those of you who don't know, If you shoot a teammate with the pap'ed VR-11, their screen will turn red and green and zombies will ignore them for around 10 seconds, enough time to revive someone.

lol, interesting, what about a pack a punched one? :carling:

oops, I was using a pap one,updated

if your shot with non-pap'd one screen still turns red i think!

you do not need it to be pack a punch it still works regular.
also im not sure if you have to pap or not but when you shoot a teammate, they have instant kill for a short amount of time

Yeah, basically:
Stock: Invisibility
Upgraded: Invisibility + insta-kill.
