How does this DLC work...like are the weapons marked on your map as a quest to find them or do you like jsut buy them, or you have to find them in random places?
It was a little confusing at first, I thought I was going to need to talk to someone at the Gun Runners for a Quest. But no, it's simply Challenges (like use 10,000 Points of Stimpacks) in your Pip-Boy.
It simply gives specific request of kill "X" with "X" or "X" number of kills with a a specific Weapon/s (GRA). So far the two 10,000 Points Damage ones were really easy this late in the Game. For example, you need to get 10,000 Points of Damage Kills with a
GRA Weapon, Deathclaws and Super Muties alone have about 800-1,000+ Hit Points. Kill about 15+ and both of those pop right away.
