My partner and I bought a 2nd ps4 for this game to play online with my brother and has now become the only reason I turn my PS4 on these days, especially with how pathetic other games and their mirco transactions are.

Having easily gotten my money's worth, my only complaint is lack of an ultra impossible to kill zombie to wreak havoc, as once you hit day 7ish~ other than the mass fire place method, it gets too easy.

So to answer OPs question, I would break my anti-mirco transaction rule if it was for some fear inducing, time to flee ultra zombie.
