it does depend on the type of thing that it is
the 'zombies' in The Last of Us are not zombies at all, not really (that's a magnificent game by the way). they are not undead, they are very much alive. it was spread through several ways, including being airborne, and was modeled after real life types of fungus that does the same thing to inscets, for example
http://en.wikipedia.org/wiki/Ophiocordy ... ilateralisIn A World... where people emphasize shades of grey, zombies intrigue us because there is no reasoning with them, but it's total fantasy that undead will come back to try to eat ur brains. i always think it goes too far, it wouldn't go that far. someone somewhere would realize that zombies are made out of things that would burn and it would have been taken care of before the world moves on into some wasteland
