Quick walkthrough

Detailed walkthrough
You will get a radio signal from Ulysses telling you that he wants an ending to things. Go to the Canyon Wreckage and enter the Divide.

Upon reaching the entrance to the Divide, a message box will appear saying: The coordinates you received lead you to this canyon filled with storm tossed wreckage. Beyond lies the Divide.

Lonesome Road is intended for experienced couriers (level 25 or higher). You cannot take companions with you on the road ahead (or bring any you find out with you). You can carry whatever equipment and gear you have with you without restrictions, however.

If the journey proves too difficult, or if you need to resupply, you can retrace your steps and return to the Mojave at any time. If you are prepared, then continue onto the storms of the Divide...history awaits.

The Divide can be reached by traveling a north by northwest path from the California Sunset Drive-in.
