I've always wondered what day PZ is supposed to start while I'm playing it. It seems like the game is geared to start at day 1.5 or day two of the apocalypse, with the infection coming in and being swift like the black-plague, infecting and turning people over the course of a day. Suddenly everyone is waking up to find Knox county under quarentine with panic and anarchy ensuing hours later. I would imagine in the completed game on day one of your game you would (if you decided to venture out of your home) see things like small groups of zombies mauling the unprepaired caught outside, people looting houses, stores and beginning to barricade their homes, the Knox Co. police holed up in their station and police car blockades in the towns trying to fight off the growing horde. The hospital's doors would be locked and barricaded as the doctors and staff would probably be the first to realize there was no hope and would lock and bar the doors to prevent anyone from entering or leaving as they succumb to infection and/or get overwhelmed and eaten by their patients that have turned. The border of Knox County would have the roads and clearings barricaded by the military who will shoot anyone, living or undead, on sight if they venture too close to the barricades . Maybe the troops will shout a verbal warning to the living to turn back before opening fire. Helicopters would patrol the thickly forested borders of Knox county, again shooting living and undead on sight, only they wouldn't have a verbal warning. This all would last for a day or two. Eventually the police station and police car barricades would be overran by the zeds, the last of the hospital staff killed and turned, a few houses and stores empty and ruined (broken windows, smashed doors), stripped of goods while other homes have had their windows barricaded over and turned into safe houses. The only thing on the streets would be wandering hordes of zeds.
