The goals of this quest are to expand the territory for the gangs, secure the parks beyond the walls of Nuka-Town USA and then decide which gangs will occupy the territories permanently. Claiming an area for a raider gang raises your favor with them. There's no way, however, to be entirely fair to the three groups. At the conclusion of the main quest, you will receive two of three possible perks based on your preference between the gangs.

Secure Nuka-World's Bottling Plant

Travel to the marked location on your map. Complete the location quest A World of Refreshment. Expect to find a new mutated breed of mirelurks, nukalurks, assaultrons and a nukalurk queen.

Secure Safari Adventure

Travel to the marked location on your map. Complete the location quest Safari Adventure. Expect to fight a lot of gatorclaws, a new deathclaw-like hybrid.

Secure Kiddie Kingdom

Expect a constant influx of radiation from water misters that someone has tampered with to to spray highly radioactive water. You'll also have to put down a lot of feral ghouls of the common and legendary variety.

Secure Dry Rock Gulch

Secure Galactic Zone

Travel to the marked location on your map. Complete the Star Control side quest. Expect laser turrets and a variety of robots including nukatron defenders, eyebots, Mr. Frothys that spray highly irradiated gas and protectrons.

Once you've secured all of Nuka-World for the gangs, return to Gage to complete The Grand Tour and start Home Sweet Home.
