Ahh you guys have some of it wrong. I see the flaw in the /fly, but its not actually fly if you read the first post. It would be water around them instead of glass, just their feet most likely to make them move slower and unable to fly. And, also, there would be a time limit before the medic can heal someone. I personally like ShinyShark's idea, maybe when a zombie touches a human, there would be 10 seconds before the human would become a zombie. This would be interesting. For marnixxie's idea of curing the first zombie, shinysharks idea would definitely be able to counter that, because medics wont cure zombies, only halfway infected humans? And the time limit between cures should be a bit long, and only 1 per time or until the medicine wears off. Hope this clears up some of the flaws. Great feedback guys :)
