Old World Blues



Old World Blues is the third add-on for Fallout: New Vegas, developed by Obsidian Entertainment and published by Bethesda Softworks.

Plot
In Old World Blues, the Courier is abducted and experimented upon by the Think Tank, a group of pre-War scientists that have replaced their aging bodies with machines. Learning that the Think Tank has removed and subsequently lost the Courier's brain, the Courier aids the Think Tank scientists in fighting Dr. Mobius, the rogue scientist currently in possession of their missing organ. Exploring the Big MT facility, the Courier re-discovers lost technology while also fighting off lobotomites, robo-scorpions, and more.

Finally meeting Dr. Mobius, the Courier learns that he is not actually evil, but has messed with the Think Tank's memories and constantly threatens them to keep them from experimenting on the entire wasteland. He also stole the Courier's brain so the Think Tank can not use it to acquire new bodies and escape. After choosing what to do with Mobius and reacquiring their brain, the Courier returns to the Think Tank and either convinces them to stop or kills them.

Quests
The experience points that are rewarded for quests are based on the players level upon quest completion. The total experience points available for the main storyline quests is anywhere between 3,000 (for levels 1-4) to 22,000 (for levels 45-50). The side quest experience points ranges from 75 to 500 per quest.

Behind the scenes

 * The Big Empty was a location that was scrapped from Black Isle's canceled Fallout 3 (Van Buren).
 * 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.
 * This add-on is an obvious homage to the science fiction B-movies of the 1950s. There are many references to these types of movies throughout the add-on.
 * Old World Blues was nominated for Best DLC Award at the 2011 Spike Video Game Awards. It was the only one of the Fallout: New Vegas add-ons to be nominated.
 * The add-on's main quest shares many similarities with the 1939 film, The Wizard of Oz in that the Courier searches for their brain (Scarecrow), their heart (The Tin Man), and their spine (courage for the Lion) after initially being unconscious after entering Big Mountain (as Dorothy was knocked unconscious in order to enter Oz). Additionally, Dr. Mobius is initially portrayed to be malevolent or sinister, much like the Wizard of Oz himself, only to have it revealed that he is quite misunderstood, and the Big Mountain Transportalponder! acts as the Ruby Slippers, taking the Courier back home.
