There are four dungeons in Nuka World’s Galactic Zone – Starlight Interstellar Theater, Robco Battlezone, Vault-Tec: Among the Stars and Nuka Galaxy. Clearing these dungeons will net you a total of 23 Star Cores – more than enough to reboot the mainframe. These are the easiest Star Cores to find because you know how many there are in each area, and once the enemies are down, it’s just a matter of poking carefully into each corner.
The Star Cores in this area can be located at Starlight Interstellar Theater, RobCo Battlezone,Vault-Tec Among the Stars and Nuka Galaxy. If you manage to clear these dungeon, you will gain about 23 Star Cores which are enough to restart the mainframe.
As you've heard, there are 35 Star Cores in total and when you find them all, you gain access to the room wherein the Quantum Power Armor is located. Now to help you out, we've listed below the location of each Galactic Zone Dungeon Star Core in hierarchical order to make it easier for you to find the ALL Star Cores, and access the Quantum Power Armor room.
Starlight Interstellar Theater Star Cores
There are four Star Cores in this short, non-linear dungeon:
Within this area,, you'll find four Star Cores. And they are located:
- From the entrance, take the left corridor until you reach the bathrooms towards the far end. Enter the men’s bathroom (blue paint) and look for a crack in one wall. There’s a dead trader in here with a Star Core.
- From the entrance, explore the right corridor until you reach the kitchen at the far end. There’s a door in here behind which you’ll find the second Star Core.
- Enter the main cinema area. There’s a console towards the rear of the room, opposite the screen, with a third Star Core.
- Take either of the elevators to the catwalks or control room above the cinema. There’s a fourth Star Core in a console in the control room.
RobCo Battlezone Star Cores
There are six Star Cores in this dungeon, but you’ll need to survive some tough robot encounters to claim them.
- From the entrance, enter the audience seating area and immediately turn left. Search along the wall for a locked door leading to a room with two Star Cores.
- Take one of the passages between the blocks of audience seating to find the souvenir shop tucked away at the back. There’s a Star Core on a shelf.
- Facing the robot battle arena, circle anti-clockwise to enter the tunnels underneath it; beware the sentry bot. There’s a Star Core on a console.
- Finally, make a save and then enter the arena itself, where you can collect two Star Cores. Three waves of hostile robots will spawn in before you can exit, so be careful.
Vault-Tec: Among the Stars Star Cores
There are six Star Cores in this confusing and occasionally deadly dungeon.
- From the entrance, take the elevator down to the start of the “ride”. In the are with rocks and Protectrons, look for a locked door hidden away from the ride path. There’s a Star Core in the room beyond.
- Follow the ride path until you reach a living room display. There are multiple exits from this room. One locked sliding door leads to a small observation room with a Star Core.
- Two of the exits from the living room area form a short loop. Along this route there’s a highly radioactive room. There’s a Star Core in this room.
- Finally, there’s a nursery off the living room display area. Pick the locked sliding door here to enter the central office – watch out for the Novatron. One of the doors in this room leads to the main observation centre, where three Star Cores and a loot chest await.
Nuka Galaxy Star Cores
This linear dungeon includes seven Star Cores. If you’re a stealth character, activating ride lighting at any active terminal can help here. Otherwise, the standard emergency lighting makes navigation much easier.
- From the entrance, proceed through the queueing lanes to the boarding area. Facing the direction the ride travels, look for a door to the right of the ride path. There’s a Star Core in this room.
- From the last room, take the door leading deeper into the ride. When you reach a large room with multiple planets, cross to the opposite side of the ledge you start on, and find some stairs leading down. Cross the room to reach a corridor, and collect a Star Core from the console part way along it.
- Continue along the corridors and take the elevator on your left. Turn left out of the elevator and find a small opening leading to the next room. There’s a console directly opposite this entrance where you can collect another Star Core.
- Proceed right through the rocky set to reach a hidden door leading to a long set of stairs leading up. When you emerge back onto the ride track, immediately turn left and climb a short flight of stairs to reach a console with another Star Core.
- At the end of the ride you can collect a Star Core and a key from a console at the disembarkation zone. Use the key on the nearby door to open a path back to the ride entrance. In the short tunnel between the ride entrance and ride exit there’s a short flight of stairs leading to an office. Collect a Star Core in here.
- Finally, enter the tiny control booth off the office mentioned in the last bullet point and grab the last Star Core from the computers.
Nuka World and Galactic Zone Star Cores
There are 12 Star Cores to be found outside of dungeons. Seven of them are found in the Galactic Zone, while five are scattered around the broader Fallout 4: Nuka-World map.
Galactic Zone Star Cores
There are seven Star Cores to be found around the Galactic Zone park.
- One Star Core is found near a corpse near the mainframe in Starport Nuka.
- A second Star Core is found in a locked display case on the upper level of Starport Nuka.
- At the base of Starport Nuka, go through the mesh gate and search the huts and sheds for a third Star Core near another corpse.
- There’s a Star Core on the console at the top of the long stairs leading up to the Arcjet G-Force ride near Nuka Galaxy.
- Facing the entrance ramp to Nuka Galaxy, search to the right for a small shed with another Star Core.
- There’s one Star Core on the console near the bottom end of the Spacewalk; if you’re coming down the ramp from Starport Nuka, it’s on your right just at the end. Approaching from Robco Battlezone, it’s on the left before you go in and harder to see.
- The final Star Core is on the top level of Starport Nuka, and is only accessible afetr completing the main story quest to restore power to Nuka World.
Nuka-World Star Cores
- To get the last five Star Cores, you’ll need to explore the whole Nuka-World map.
- On a table in the Nuka-Town Market.
- Inside Nuka-Cade; turn right from the entrance and head back into an employee area.
- In a barn north east of the junkyard found in the south west of the map (the Hubologist quest will take you to the junkyard if you’re having trouble finding it).
- South of Doc Phosphate’s in Dry Rock Gulch, near a corpse.
- Near a corpse in the Nuka-Cola Bottling Plant; face the Quantum area and turn right to locate it.
Star Core console ID
Look, we all know there’s no point playing games if you’re just going to cheat all the time, but we also know it’s very tiresome to do a bunch of fetch quests when you just want to shoot robots and pick pockets. So you’d be forgiven for wanting to spawn in 35 Star Cores through the console and tick the quest off that way.
Well, tough biscuits: it doesn’t work. Star Cores spawned with the console (ID 0601E367) can’t be installed in the mainframe. Buh-bow.
If you really want to cheat your way through Fallout 4: Nuka World, you’ll need to use the console to advance the quest stage until you have “collected” all 35 Star Cores, and then install the 35 Star Cores you added to your inventory. You could also just no-clip through the display case and grab the power armour if you don’t mind the quest hanging around unfinished in your journal.
