Star Control

Star Control is a side quest in the Fallout 4 add-on Nuka-World.

Detailed walkthrough
Upon approaching the Galactic Zone, the player will notice a large amount of corpses and destroyed robots lying around outside the entrance. One of the bodies is that of Tiana, who has a holotape on her. Read the tape to prompt the finding of the Star Control mainframe, located at Starport Nuka near the center of the zone.

Once through its glass door, (after admiring that Quantum X-01 armor) the back wall has the mainframe. It requires a Star Core to boot up, which can be found in the hand of the nearby corpse of Kendell Alston. Affix the Core to one of the many empty panels surrounding the mainframe to activate it. From here you will be required to locate the remainder of the Star Cores. There are 35 in total, including the one Kendall was holding.

In the Starlight Interstellar Theater, one Core can be located on a panel through the theater's pantry, down the corridor to the right of the entrance. The key to the door is on the kitchen counter. A second one is located down the opposite corridor to the left of the entrance, in a hole in the wall of the bathroom. The third is located in the centre booth of the theater room itself, guarded by sentry bot Startender. The fourth is upstairs, powering the projector.

In the Robco Battlezone, one Core is on the lower level to the right when facing the stairs, in the store section behind the checkout desk. Be sure to pick up the Nuka-Ray recipe book on the shelf. Two more cores are located in the arena; entering it will cause the doors to lock, releasing robots into the room. Another core is beneath the arena, down a staircase to the side of the arena's entrance. The final two cores are above the entrance, accessed by the keys that are under the arena or on a table near the arena entrance.

A Star Core can be located to the right of the Dry Rock Gulch's refreshment stand.
