How to Start Nuka World
If you've got the 1.7 update and Nuka World on board your PC or console, it's time to dig into the new content.
Once you've confirmed Nuka World is properly installed on your system, you'll want to load up your saved game.
If your character is level 30 or higher you should get the "All Aboard" quest automatically. You will be required to listen to Nuka-Cola Family Radio for instructions. Listen and you'll be on your way to Nuka World.
If you aren't level 30, starting Nuka World is a little more involved.
If you're a lower level you'll want to explore on your own and find the “Nuka-World Transit Center." The location is way out west on the map, outside of the game's original play area.
To find it, follow the more northerly of the two highways that take you off the western edge of the map. Nearby locations include “Lonely Chapel”, and “Federal Ration Stockpile." They are to the east of the location you're looking for.
