You take your eyes off the road to look at the surrounding landscape.
This is what you see from your West window. The sun is not going to be up there for very long. There are some rolling plains and very high mountains further off to the distance.
To kill some time, you decide to go reflect on how you got to this situation in the first place. Let's start from the top.
It was three years ago, the year 2008. This year will be engraved forever in history as the beginning of the global undoing. It was this year that the peoples of Earth were struck by a mass amnesia, which was followed by an age of mass hysteria and panic. To this day the remaining survivors don't know what caused this total amnesia. The events that followed the "Age of Panic", however, were far more horrifying than anyone would ever expect.
Monsters. The living dead. The walking tormentors. The eternal damned. There were many names for the atrocities that haunt the world today. Some call them zombies, whatever that means. Anyone not of this world would find it very difficult to understand the physical properties of these horrors. Some are fast, some are slow, some are enormous. The smartest of the survivors have determined there are various classes of these monsters. The most common were dubbed "crawlers" because of their slow movement. There are other classes much more dangerous, smarter, faster, stronger than crawlers. They are mercifully uncommon mutations of the generic monsters.
Fast-forwarding to the present, you banded together with a group of a couple-hundred survivors, working to survive. Your group has no name, but faraway settlements call you the "Tangos". Your job under this group is to pilot one of few available automobiles and search for unaffiliated survivors to absorb into the group.
So here you are, doing your job, trying to get these survivors back to the regroup point to be probably towed back to a safe location to stay for the night. Man, if you can't get back with the car the guys are gonna chew you out soooo bad!
