What is it with zombies anyway? Darn things seem to be everywhere lately, especially in places they oughtn't. So how did the whole craze get started? Or were they there all along and I just never noticed, except maybe around Halloween? Inquiring minds wanna know.

That said, I might just enter this. Question: must there be visible zombies or can I just let 'em lurk menacingly in the shadows while my hero readies for battle and looks appropriately awesome?
