Fallout: New Vegas - Old World Blues, the next DLC instalment for the hit RPG sequel, will be released for all formats on July 19, Bethesda has announced.

Prior to the DLC release a new title update for New Vegas will be rolled-out, adding support for the new content and improving performance and stability in major game areas.

In Old World Blues players will discover how some of the Mojave's mutated monsters came to be when you unwittingly become a lab rat in a science experiment gone awry. You'll need to scour the Pre-War research centres of the Big Empty in search of technology to turn the tables on your kidnappers or join forces with them against an even greater threat.

The content will be available for download on Xbox LIVE for 800 MS Points, PSN for £7.49, and both Steam and Direct2Drive for £7.49. Lonesome Road DLC will follow at a later date.
