Bethesda Softworks has just released the trailer for Lonesome Road, the fourth add-on pack for Fallout: New Vegas, coming out on September 20th.

In Lonesome Road you are contacted by the original Courier Six, a man by the name of Ulysses who refused to deliver the Platinum Chip at the start of Fallout: New Vegas. Ulysses promises the answer as to why he didn’t take the job, but only if you make one last journey into the hurricane-swept canyons of the Divide, a landscape torn apart by earthquakes and violent storms. It’s up to you whether you take the job or not.

Lonesome Road will be available for download on Xbox LIVE, PlayStation Network and Steam (Xbox LIVE for 800 Microsoft points, PlayStation Network and Steam for $9.99). For more information on Fallout: New Vegas or Lonesome Road please visit http://fallout.bethsoft.com.
