We all know that call of the dead introduced VR-11 which is a wonder weapon, meaning that it is powered by 115 so if 115 can turn someone into a zombie it can reverse it! Now in Turned you know there is the cure but that can just mean it was just for fun but maybe there is a backstory to it because if they wanted us to play as the zombie then wouldn't they just put that one person is a human but they made a cure which made a whole bunch of theories about curing people but anyways the intro in Die Rise shows Samuel eating what looks like an arm but while that's happening he looks like a zombie so that could mean he got cured or shot with the VR-11 but because he was once a zombie that could mean that thats why he is the only one that can hear Richtofen so that means that there is a way to cure people maybe only few people but THERES A CURE
