So this has been going through my head for awhile, maybe every round, there is one random super zombie and one super human. A super human would be a special human that can only be infected by a super zombie, unless every other human is caught and s/he's the last human, making him/her any zombie's game. A super zombie would function as a normal zombie, infecting any player, but also has the ability to infect the super human at any time. It's only an idea, but maybe would change things up. This can be every round, every few rounds, special occasions. Also there can be more than 1 super zombie if its too pro-human for that 1 special super human. If this can't be coded or implemented it's fine, worth a shot! :) Thoughts? Responses?
