In response to the OP Id definitely seek high ground where I could see enemies coming. I'd set numerous traps (like the ones in Rambo first Blood!) haha. Fashion myself some sort of spear ATLEAST and maybe make a bow using my shoelaces as an improv bow string. I'd try and go for more of a "let them come to me" kind of thing. Than go for attack mode! Alternatively I'd try and find a safe place that's secluded and well hidden, sleep during the day whilst everyone else is on the move and then I'd move at night killing people whilst they sleep. Morbid thought I know. But you gotta do what you gotta do to stay alive! There is plenty more, spent all of last week debating this with friends at work after we went to see the film. But only a couple of us have read the book.
