I would man up pack up and look for survivor and a cross bow cause wen it comes to walker must keep silent if not look for a safe place barricade it and hold of their for a few days then move out looking for supplies n ammo (bows)
(If it isn't like Resident Evil) Avoid all zombies as much as possible while resorting to the roof of a grocery store, building some sort of shelter. Then I start making noise as to lure any zombie close to my whereabouts and proceed to kill them (headshots only) from the top of the store so that their bodies work as a sort of zombie repellant and to mask my scent. Therefore the remaining zombies result into leaving the area because they no longer smell anything living. I then take one of the many rotting corpse and make a disgusting body suit of zombie flesh, so that I may gather any sort of supplies I will need later on. Non perishable foods and the such.......and twinkies. From then on I proceed to live with caution and success.
