Bad luck.. You find a bunch of zombies just wandering the inner city and when they see you, you know it's the end for you. But let's say, for the sake of story continuation that you've been watching too much 'The Walking Dead' and decide to give whatever you learn from the show a try. Would you..
kill zombies like a boss
live in hiding and hope for a miracle
give up and kill yourself, who wants to live in a world where you have to constantly run anyway
run away with an imaginary ™Pony - as far as you can
