You find yourself in a dark cellar with some other frightened people taking refuge from an outbreak of zombies which roam the land around the house, but as far as you know haven't made it inside. There are enough supplies and water to survive in the cellar for a few days, if you need to. Naturally you don't want to either die from thirst or from being eaten alive by hoards of the undead.So do you stay in the cellar, or venture out?
Dying from thirst or hunger is no joke. I'd venture out. Bio Hazard and Silent Hill series asume the protagonist is some kind of phyical unfit office worker, with no fighting abilities(Until the later versions, for example, BH4, where Leon Kenedy gives some flashy kicks)
