A Pair of Dead Desperados, I

A Pair of Dead Desperados, I is an unmarked quest in Fallout: New Vegas.

Synopsis
The Vikki and Vance Casino is the jewel of Primm, boasting an extensive exposition devoted to Vikki and Vance. However, upon closer inspection, the exposition is woefully incomplete...

Walkthrough

 * Upon examining the plaques, the player can learn that there is supposed to be a complete set of costumes on the mannequins and more importantly, the pristine submachine gun Vance had in the car on the day he and Vikki were killed. However plain their absence, Primm Slim will not acknowledge that.
 * The solution is to use Science 50 to make him rescan and reformat his memory, discovering a corrupted memory block that contains a recording of the theft, obscured by the thieves' hacking. The recording implicates a pair of desperados... Which can be found at the Wins hideout on the other end of the Mojave.
