Wrong Way: The Truth

On your way home from work, you seem to have gone the wrong way and find yourself in a place you are unfamiliar with. In an attempt to get an idea of where you are, you start wandering around to see if there's anybody around. There doesn't seem to be anybody, despite all the buildings around, oddly enough. But you could swear you keep seeing movement out of the corner of your eye. Oh well. You found a small piece of a map, maybe the rest of it is around somewhere and it could help you? It's your best bet it seems.
