Chuck can still carry on even if Katey were to become a zombie. You can try doing the 72,000 kills achievement and not save Katey. Then your goal would then have to be get 72,000 kills before the military arrives. A look at Chuck's face has to be that he might of been busy getting that 72,000 zombie kills and did not make time to do a single main story missions.
Great game see you in part two 😊🇬🇧

I guess that is still a level of becoming a psycho in some way.
