Does anyone here know or know where I could find a list of the perma-perks in zombies and how to achieve them. I know about the permanant quick-revive and the metal barriors, also the headshot perk but I think I'm unaware of a few others.
you can get jugernog if you get down by the same zombie twice in a row, it has to be on solo play though, so just do it in tranzit, yuo can do it right of the bat, get quick rivive, get down, once you revive get down by the SAME zombie, you should have the perk now, i dont know about any more perks apart from the once mentioned by you
There is a fairly decent CoD wiki that's a short Google search away. If I recall, they do have an article on what you are searching for.
