Everyday is a fight for your life now. Some days you win that fight and you're lucky and you survive, others might not be so lucky. There's a key to all this and survival, and rules even though there aren't rules anymore. An those are, NEVER GO ALONE, ALWAYS carry both a gun and knife and use the knife as much as possible because noise attracts them, go straight for the head headshots take them down, never be sorry or hesitate for taking one down (as in a loved one or friend) once they change they are no longer the person you knew. Rashen food water and supplies, learn at least first aid, be aware of your surroundings and watch your back. Also remember that there is now no rules and this is the ultimate fight to survive, money doesn't mater anymore. You don't kill the living unless they try to kill you first.
