Lonesome Road

Lonesome Road is the fourth and final add-on for Fallout: New Vegas, developed by Obsidian Entertainment and published by Bethesda Softworks. Originally scheduled for release in July 2011, Lonesome Road was delayed and subsequently announced for an August release. It was later announced that the add-on had been delayed a second time. It was finally released simultaneously on all platforms on September 20, 2011. This concludes the story arc beginning with Dead Money chronologically, finally answering the foreboding clues given in add-ons past.

Synopsis
Lonesome Road brings the Courier's story full circle when they are contacted by the original "Courier Six," a man by the name of Ulysses, a former frumentarius of Caesar who refused to deliver the platinum chip at the start of the main storyline in Fallout: New Vegas. In his transmission, Ulysses promises the answer as to why, but only if the Courier takes one last job; a job that leads them into the great depths of the Divide, a landscape torn apart by frequent earthquakes and violent storms. This is the fabled location of the battle between the Courier and Ulysses. The road to the Divide is a long and treacherous one, and of the few brave enough to walk it, none have ever returned. The first quest in this expansion begins with The Reunion.

Behind the scenes

 * "The Lonesome Road" is the name of a 1927 song by Nathaniel Shilkret and Gene Austin, which has been covered by several musicians who should be familiar to fans of the Fallout series, including the Andrews Sisters, Louis Armstrong, Eddy Arnold, Bing Crosby, Peggy Lee, Nat King Cole, Sid Phillips, Stan Kenton, Frank Sinatra and Kay Kyser.
 * Three holotapes that can be found in Lonesome Road were first released on Bethesda's official website prior to the add-on's release.
 * Ulysses makes frequent mention of "the Bull and the Bear" when referring to Caesar's Legion and NCR, respectively, in reference to the symbols on their flags.
