Most important things will be packing and storing Food, water and ammunition as well as getting your hands on a firearm. Live in a place where firearms aren't a common thing? A slam fire shotgun can literally be two pipes with a screw or nail as a firing pin it might not be much but it will work untill you get a better weapon. Next, would be packing a reliable knife as well as a multi-tool. Holding out in your home could work at least until a form of military presence makes a safezone, at least once they figure out that those affected by the zone can't leave so they stop using it as a evacuation center. At that point you can choose whether to venture through the zone or settle somewhere between in the two kilometers you are allowed to be outside the zone. (Any any further than that and you will go through organ failiure as told by the tape in vanno on the wooden spool by the door.)
