Less than a day from release of the Lonesome Road, Bethesda uploaded the third holotape on their Blog.
History follows strange roads, and it can follow you no matter how far you walk. This is the third of several holotapes your Courier can discover in Lonesome Road, and helps shed more light on New Canaan, the White Legs, and Graham.The rest of the holotapes? They are for your Courier to find in the Divide. Perhaps the history within them holds the key to the future.
You can listen to the third recording here.
