It is the dawn of a new age of mankind.  Approximately three months ago, bodies of the recently dead began reanimating for unknown reasons.  At first the zombie plague spread slowly but it soon broke free of any attempted containment and rampaged across the earth.  Government has collapsed and you haven’t even heard an emergency radio broadcast for about a month.  You have left your current sanctuary in search of other living humans or remnants of civilization.  Quickly you find that large roads and freeways are clogged with traffic and the walking dead, so you stick to small country roads that avoid large cities.<br/><br/>While traveling through rural Missouri, you hear what sounds like music drifting on the wind one afternoon.  You head towards the general direction of the sound the next day, keenly aware that Zack might have heard the noise as well.  While traveling west on Route 8 you see an interesting sight at the intersection with Route 21 as you enter Potosi.  There are a few abandoned cars on the side of the road, and a tractor trailer blocking the road north.  There is a large dent in the side of the trailer and approximately 80 destroyed zombies radiating out from the point of impact.  The stench of rotting flesh is nearly overwhelming in the late June heat, but you approach closer to investigate.<br/><br/>Most of the zombies’ heads are completely missing or heavily damaged.  In addition, some of the bodies have been cut in half or had large sections torn out.  You find hundreds of brass casings near the trailer, and while some look familiar most others are larger than anything that you have ever shot; maybe half an inch wide and about 4 inches long.<br/><br/>Whatever impacted the trailer is gone now, but you can see the bright green anti-freeze drips that proceed down Route 8 into town.<br/><br/>As you follow the drips into town, you don’t see a single zombie among the houses and shops.  Several blocks later, (intersection of High Street and Missouri) you see an Army humvee parked near the front door of what appears to be a church or town hall (http://en.wikipedia.org/wiki/Image:Potossi-courthouse.jpg).  The land in front of the building is covered with between two and three hundred dispatched zombies.<br/><br/>One of the top windows of the building has been knocked out and you can see a thin man with a rifle waving at you.<br/><br/>
