Bethesda has delayed the launch of the fourth Fallout: New Vegas downloadable add-on, Lonesome Road.

"We just wanted to drop in here and let you know that due to circumstances beyond our control, Lonesome Road wont be out this month," senior producer Jason Bergman wrote on the Bethesda forum.

"This isn't due to any major issue with the code or content, but there are lots of factors involved in releasing these things, and one of those is causing us to slip past our intended release date."

Bergman, while unable to provide fans with an updated release date, did say the development team was working to get the DLC out as quickly as possible.

"We'll be announcing the final date, along with a couple of other interesting FNV-related items in the near future."

Meanwhile, Bethesda released the first screenshot of Lonesome Road, which you can see below.
