Hi everyone, I don't know anything about the Gun Runner's Arsenal other than I have it. It came with the Fallout New Vegas Ultimate Edition but I don't even know what it is, how do I start it, and how do I use it. Any takers?

Thanks, G

As soon as you get the pop-up GunRunnersArsenal (GRA) weapons, ammo, mods (some workbench and reloading bench recipes) will be available in most stores though most of these things are costly.

When you buy a weapon mod (GRA) it will only work on the (GRA) version of the weapon, the ammo however works in all weapons.

Hope this helps!
