I made this mod because I wasn't satisfied with the other DLC integration mods available. However, by no means I imply that this one is superior, just a different take on the concept. As with all integration mods, this will conflict with other mods that alter the leveled lists. Obviously it requires Far Harbor and Nuka World, but also Automatron since the mod adds the other DLC weapons to the Rust Devils.

DLC weapons will start appearing around the same level as assault rifles normally do (mid 20s) but will not completely replace other weapons; raiders will have roughly the same chance of using a handmade rifle as an assault rifle. Radium rifles are carried only by the Children of Atom and since level 1, just like the gamma guns. The weapons and ammo will also be available for sale from most vendors at the same levels. 7.62 and .45-70 rounds have also been added to the scrounger pool.

As side tweaks, the .44 revolver now shows up at the same levels as the combat rifle. 5.56 ammo is available as random drops much earlier as this was meant to be used with WeaponEdit, which makes the combat rifle use 5.56 rounds instead of .45, but otherwise it just means you can start getting the ammo for the vanilla assault rifle earlier.

Finally, I added Nuka-Cola to some containers which would make sense, like wooden boxes, coolers, and most pre-war stuff. They also have a chance of being carried by humans, just like food, other drinks and chems.

To avoid having to add another DLC dependency, I didn't add the ammo to the ammunition plant from the Wasteland Workshop DLC. Just use this instead if you haven't it already:
