And just like these ghost stories, there are many secrets to discover on the map, including 22 undiscovered areas. If you unlock all these areas, you will receive the No stone left unturned completion/trophy and another step towards 100% completion.
It is also very handy to have a disguise for this mission, because there are not many places you can enter without one.
