Excellent product that is specifically related to it's exact description. It portrayed in bulk and quite cleverly the attempt to delay a Zombie outbreak and, as it dramatically develops, the wish by the military to presume they can actually stop it. It could be used with any system of gaming and you could enter play at any time. It allows copying a small skirmishes and clear out small communities to an all out linked group of scenarios with several major battles. By leaving out any attempt of rules, the book has delivered a quality scenario and I eagerly await the next book.
