Quick question: Anyone else having trouble passing on the viral Living Dead achievement?
Background: I got the viral achievement a while back & passed it on to at least a dozen people with little to no difficulty. I recently picked up the DLC pack & played with a friend. Since that time, I have tried to help two people with the Living Dead achievement & it has not worked. We tried different game types, switching hosts, ranked & player matches, even tried deleting the DLC off the hard drive. Nothing seems to work.
Thanks for any information you have. I posted a separate thread in the forums too.
