I think I recall this being a long time experience issue side of things. In real life as you may be aware tunnels are meant to be pitch black unless they have lighting systems,etc. I am very certain all routes in TSW have what is called "tunnel fog" which really ruins the simulation aspect when you make your way through a tunnel. It can be a very magical experience going through a tunnel and very hard pounding as well but this tunnel fog issue really ruins everything. Really wish this is fixed
