You’re trekking through the neon-drenched, rusted-out remains of the Galactic Zone in Fallout 4’s Nuka-World DLC, and honestly, it’s a total mess. Between the sentry bots trying to turn you into a puddle and the sheer verticality of the Starport Nuka, it’s easy to get overwhelmed. But the real headache? Galactic zone grounds star cores. These little circuit boards are the only things standing between you and the Quantum X-01 Power Armor, which is arguably the prettiest—and most functional—set of armor in the entire game.
Collecting them feels like a scavenger hunt designed by a sadist. You need 35 to unlock the display case. If you just want to get the park’s power back on and satisfy the "Star Control" quest, you only need 20. But let’s be real. Nobody comes to Nuka-World to settle for "enough." You want that shiny blue suit.
The Ground Floor Chaos
The Galactic Zone is basically a massive circle of death. Most players make the mistake of running straight into the RobCo Battlezone or the Vault-Tec Among the Stars. Big mistake. You've gotta start with the galactic zone grounds star cores first because they’re the easiest to grab while you’re dodging lasers. These are the cores sitting out in the open, not tucked away inside a loading-screen-heavy sub-location.
Think of the grounds as the connective tissue of the park. There are seven cores just chilling in the outdoor areas. One is tucked away near a dead trader behind the Starport Nuka. Another is sitting on a console near the base of the spire. If you aren't looking at the floor or the junk piles, you’ll walk right past them. It’s kinda funny how Bethesda hid some of the most important items in the game in plain sight, usually next to a skeleton that clearly died trying to do exactly what you’re doing.

Why the Star Control Mainframe is a Liar
The Star Control terminal is your best friend and your worst enemy. It tells you how many cores are in each section—like "Galactic Zone: 7"—but it doesn't tell you where they are. When the terminal says "Galactic Zone," it specifically means the exterior grounds.
- One is in the locked shed near the entrance to the RobCo Battlezone.
- You’ll find one on the body of a fallen trader near the entrance to the park.
- Check the top of the Starport Nuka (though some are locked behind the endgame power requirement).
- There's one near the Nuka-Cola bottling plant path.
Most people get stuck at 34 cores. It’s a rite of passage. That final core is almost always the one tucked away on the very top level of Starport Nuka, which is inaccessible until you finish the main Nuka-World storyline and turn the park's power back on. It’s a bait-and-switch. You spend hours hunting, only to realize the game is hard-locking you out of the prize until the credits are basically rolling.
Beyond the Grounds: The Interior Grind
Once you’ve cleared the galactic zone grounds star cores, you have to head inside. The RobCo Battlezone is a nightmare. You’re forced into an arena fight against waves of sentry bots and assaultrons. If you're playing on Survival mode, this is where most runs go to die. There are 6 cores in here. My advice? Bring a lot of Pulse grenades. Or just hide in the upper stands and let your companion take the brunt of the fire.

The Vault-Tec Among the Stars attraction is more of a psychological test. It’s a winding, confusing path through a "future" colony on Mars. There are 6 cores here too. You have to check every side room and closet. Most of them are plugged into wall terminals that look exactly like the background scenery. It’s easy to miss them because the lighting is so dim and everything is coated in that sickly green irradiated glow.
The "Secret" 35th Core Strategy
A lot of players think you must finish the "Power Play" or "Open Season" quests to get the final core. Technically, that’s how Bethesda intended it. However, if you’re impatient (and who isn't?), there’s a notorious respawn glitch. If you wait 48-72 in-game hours away from the Galactic Zone, the core located in the junk shed near the RobCo Battlezone has been known to respawn in certain patches of the game. It’s not a guarantee, but for those who want that Quantum armor before they’ve even met the Pack or the Disciples, it’s a gamble worth taking.
Technical Nuance: Why the Scavenge Matters
From a game design perspective, the galactic zone grounds star cores represent a classic "breadcrumb" mechanic. They lead you to the edges of the map. By forcing you to find these cores, the developers ensure you see the scale of the Galactic Zone. You notice the detail in the "Starlight Interstellar Theater" or the way the "Nuka-Galaxy" coaster looms over the skyline. It’s world-building through chore-work.

Is it tedious? Absolutely. Is it rewarding? When you finally hear that "clink" of the 35th core hitting the slot and the glass door slides open, yeah, it feels pretty great.
Real Talk: Don't Forget the Scav!
The Scav! magazine #5 is also in this area, specifically on a table in the employee-only area of the Starport Nuka. If you're hunting cores, grab this too. It gives you a massive bonus to strength and endurance if you have low caps. It’s one of those "while you're there" items that separates the casual players from the completionists.
What You Should Do Right Now
If you're currently staring at the Star Control terminal and pulling your hair out, take a breath. Don't just run around aimlessly.
- First, clear the perimeter. Walk the entire outer fence of the Galactic Zone. You'll find three cores you probably missed just by staying on the edges.
- Second, hit the Starlight Interstellar Theater. It's the smallest interior and has 4 cores. It's the fastest way to boost your numbers without getting into a 20-minute firefight.
- Third, accept that you might not get the Quantum X-01 until the end of the DLC. If you're at 34 cores and the grounds are empty, just go finish the story. The elevator to the top of the Starport will unlock once the power is on, and the last core will be waiting for you right next to the armor.
Stop looking for "hidden" underground bunkers. Most of the galactic zone grounds star cores are sitting on bright yellow consoles. If you see a computer screen that’s still glowing in the dark, walk toward it. Chances are, that’s your ticket to the best armor in the Commonwealth.
