Well, at the next zombie apocalypse I'll know what to expect... now the only problem that I have is buying the guns and ammunition (this is not easy in Europe, Mr Brooks should know that not all of us live in Texas 
)
I've already destroyed the stairway to the second floor, just to be sure. 
I would give 10 Stars for a german localized guide, thinking that here is not legal to own katanas and submashine guns, and that the high density of population would not allow to find remote and secure areas as easy as in Australia for example.
3 1/5 Stars and a good example of Poe's law.
