Thank you for removing friendly fire in living dead. I asked for this many times for over a year and finally it happened.
I can now finally play this playlist without people betraying me for no reason, ruining my sprees, and frustrating me.
When I am the zombie I play very sneaky, and it results in people running up and betraying me about half the time. It got to the point where I couldn’t play anymore, but now I can again. 
(pssst… now put stats up for squad dlc)
