Bethesda and Obsidian have released a batch of new screens for the next installment in the Fallout: New Vegas DLC roll out, with the impending July 19 release of Old World Blues for PC, PS3 and Xbox 360.

In Old World Blues, releasing in June, you 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 centers 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.

Alongside the new story, the game's level cap will be raised by five and new traits will be introduced. No companions will be able to accompany you, though this time around the setting is open-world and you won't lose all your equipment at the beginning.
