There is one -using the game console- right?
The map in Pathologic is actually rather brilliantly done. It is rare that one can go directly from any point to any other point. So this means that it takes slightly more time to get from one location to another. There is an upside:
There are normally two or three routes you can take between any two points that are about equally fast. This means that it is actually far less tedious to walk than almost all other games are.
I use this time walking for brooding over the plot line, speculating about the future and basking in the atmosphere of the town streets. The layout of the town varies and there are a lot of interesting vistas if you are enjoying the art as you go. Anyway, I hope this helps.
