“The famous weapons manufacturer, Gun Runners, has opened up their exclusive cache of armaments, including new weapons, weapon mods, ammo types and recipes. Their inventory doesn’t come without a price, though. Trek far and wide throughout the Mojave Wasteland in search of this elite class of weapons that range from the outrageously potent to the bizarrely impractical.”— Official description
This add-on increases the number of unique weapons, weapon mods and powerful ammunition types and adds other ammo recipes to be discovered in the Mojave Wasteland. This optional content also adds new challenges and more achievements and trophies. It originally had a cost of $3.99 or 320 Microsoft Points.
Note that in some cases, weapon mods will require the "GRA" version of the weapon for a modification to work. In other cases, any version of the weapon will suffice. See specific weapon modifications and/or weapon pages for details.
Occasionally, GRA weapons will appear in inventories at shops that would not usually have them, such as the Sprtel-Wood 9700 spawning at Mick & Ralph's as well as the Van Graffs or Gun Runners Kiosk. This can lead to players getting two or more copies of the same weapon. However, it seems that the game crashes whenever a weapon is purchased for the second time.
Xbox 360 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. Also, if the add-on is only just downloaded and the achievements for this DLC do not show up on the list at all then re-download with no games running and then play New Vegas once the download is complete, this should solve the problem and should be tried first.
Playstation 3 Vendortron updates its inventory whenever the player fast travels when this add-on is installed, the Courier's Stash add-on is installed, or both are installed.
Xbox 360 The blue flame from The Cleansing Flame will not always appear to exit the barrel. The world space will still react and it still does damage, but no flame will exit the weapon. Sometimes this can be solved by going into third person, but it will disappear once you return to first person.
Playstation 3 Occasionally, when players equip the katana with the protective sheath mod multiple sheaths will appear. To fix this, equip another weapon and re-equip the katana until only one sheath is present.
Xbox 360 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.
PCPlaystation 3Xbox 360 If Gloria Van Graff is hostile to you due to the companion quest Heartache by the Number and you installed GRA, 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.
Playstation 3Xbox 360Chet 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.
Xbox 360 Can restart other add-on saves such as Honest Heart and Old World Blues.
Xbox 360 Followers will sometimes drop GRA items, and you will be unable to pick them back up.
Playstation 3 Follower dismissal terminal might disappear randomly.
Playstation 3Xbox 360 If companions have GRA weapons on them upon entering casinos the weapons will be removed from their inventory, but will not be replaced upon your exit.
Xbox 360 Certain GRA guns do not appear in the Vendortron's inventory.
↑Question: "If one of the most confusing things in FNV for players was the inclusion of lots of different types of ammo why did you make a DLC that added even more ammo types?Also why didnt you make the changes suggested in your Fallout weapon skills blogin your mod?" Joshua Sawyer: "One of the reasons we never "drop" ammo subtypes in the world (with very rare exceptions) is to make the entire subsystem optional. If a player never buys an ammo subtype or never crafts an ammo subtype, he or she may never see ammo subtypes outside of a store. There are a still a lot of base ammo types, but that's much more manageable over time.
GRA is an optional DLC. In the same way that Old World Blues is for players who like a specific type of humor, GRA is for players who want tons o' guns*. DLCs allow us to be more specific with the type of content we create.
Making the weapon changes I suggested would be a pretty significant undertaking, possibly taking as long as everything else I did in the JSawyer mod. I didn't really have the time to tackle it.
* I believe "Tons o' Guns" was a working title for GRA early in development." Josh Sawyer Formspring answers
