So the point in PZ is to show how long you can survive. I get that part, but maybe, I just noticed it, there is a diffrence between what I mean by cure and what you mean, as im saying again MAYBE. So what I meant under the cure was something that is like the antidote in DayZ. You get sick, take a pill or something like that, and it gives you time to survive a bit more, then you have to search for it again, and again, and again until you die. This is the one I want in the story and ONLY in it, because it will give you a better chance to finish the game. However itcan be removed on higher difficulties But the cure for the zombie infection itself in whole(the one you meant,maybe) would be like an ending (From this there could be multiple endings). If ANY of this is still not possible well then maybe I shouldn't be playing PZ. However it is a good game, but without the cure it is just plain hardcore, no room for mistakes, you die you start over, something that Hotline Miami has in common, but it's diffrent.
