Old World Blues

Old World Blues is the third add-on for Fallout: New Vegas, developed by Obsidian Entertainment and published by Bethesda Softworks. It is scheduled to release simultaneously on all platforms in June 2011.

Plot
In Old World Blues 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 will 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.

Overview

 * Like all New Vegas add-ons, Old World Blues will raise the level cap by 5. Also, the add-on will offer a new trait (and respec your own traits if you've already chosen them) that will allow you to cap your level at 30 (or current level if you’re already over 30).
 * Old World Blues will, at some point, allow the player to alter the looks of their character.
 * Equipment will not be stripped from the player at the beginning of this add-on, and it features an open-world setting.
 * Like all New Vegas add-ons, companions cannot accompany the Courier to the new land.
 * In Old World Blues, some robotic appliances have personalities, all with different voices.
 * There will be a "home base" of sorts for use in this add-on.

Behind the scenes

 * In Dead Money, Father Elijah describes the Big Empty as "a treasure box, a scientific graveyard of Old World misery". Additionally, mentions of the Big Empty act as a trigger for the Things to Come! challenge. The Big Empty was a location that was scrapped from Black Isle's canceled Fallout 3.
 * At some point, Chris Avellone set his location on his Twitter profile to Big MT, Mojave, placing the Big Empty as a location within the Mojave Wasteland and thus teasing its possible appearance in a future Fallout: New Vegas add-on. Since then, Avellone has also changed his Twitter avatar.
 * J.E. Sawyer has suggested that Old World Blues will be the most humorous of the New Vegas add-ons.
 * "Mean Old World Blues" is the title of T-Bone Walker's 1945 remake of his 1942 opus, "Mean Old World".
