Gun Runners' Arsenal

Gun Runners' Arsenal is one of two item pack add-ons for Fallout: New Vegas developed by Obsidian Entertainment and published by Bethesda Softworks.

Release and availablity
Gun Runners' Arsenal was released on September 27, 2011, exactly one week after Lonesome Road, along with Courier's Stash. It was released simultaneously for Xbox Live, PC and PlayStation Store. It costs $3.99. However, due to what appears to be a pricing error, Gun Runners' Arsenal only costs £1.59 ($2.40) on the UK PSN Store and €1.99 (about $2.70) on the European PSN store.

Like all add-ons, Gun Runners' Arsenal is included in the Fallout: New Vegas Ultimate Edition, released on February 7, 2012 for all platforms.

Overview
Due to the ongoing conflicts through the Mojave, the famous weapons manufacturer, the Gun Runners have begun to manufacture and import more and more weapon stockpiles to sell to belligerents in the upcoming Second Battle of Hoover Dam. Thus, there is an increase in the number of weapons floating around merchants, both major and minor. In addition, a number of unique weapons, weapon mods, ammunition types and recipes are floating around, along with new challenges and achievements.

Behind the scenes

 * J.E. Sawyer recalls a working title for Gun Runners' Arsenal being "Tons o' Guns".

Bugs

 * If Gloria Van Graff is hostile to you due to the companion quest Heartache by the Number and you installed the add-on, the Vendortron will not sell the GRA weapons that are originally sold by Gloria Van Graff, even after killing her. If the Vendortron resets his inventory, the GRA weapons will still not appear. This results in being unable to attain some of the GRA weapons such as Sprtel-Wood 9700 (GRA), Cleansing Flame (GRA), and The Smitty Special (GRA). Uninstalling GRA, killing her, then installing GRA fixes this problem.
 * The Vendortron updates its inventory whenever players fast travel when this add-on is installed, the Courier's Stash add-on is installed, or both are installed.
 * The achievements were not listed correctly when the add-on initially came out. This resulted in the game registering the achievements unlocked but not appearing in Xbox Live profiles. This can be fixed by deleting your gamer tag from your Xbox then recovering your profile and re-earning the achievement on a new save file.
 * Some of the achievements may not unlock correctly when players meet the requirements, particularly the star challenge achievements. This is repairable by reverting to an earlier save and trying again.
 * The vendortron, as well as all other vendors in the game, will reset its inventory. However, it sometimes takes far longer than it should, particularly if you rarely use a particular shop.
 * Chet in Goodsprings and Cliff Briscoe in Novac will respawn new weapons mods (usually 3 will be available) in their selling stash by leaving and re-entering their stores, without waiting the normal 3 in-game days.
