You’re out in the deep black of the Settled Systems, probably just trying to upgrade your ship or finish a mundane delivery, when the Crimson Fleet storyline drags you into one of the most mechanically specific missions in the game. Starfield Port in a Storm isn't just another "go here, shoot that" objective. It’s the culmination of the "Buried Secrets" arc on the planet Bannoc IV, and if you aren't prepared for the environmental hazards, your hull is going to turn into space dust before you even see a docking bay.
Bannoc IV is a nightmare. Honestly, the first time I flew into that system, I thought my game was lagging. It wasn't. It’s the electromagnetic storm. This mission requires you to navigate the atmosphere of a gas giant while a literal lightning storm tries to strip your shields and eat your reactor. Most players get stuck here because they try to brute-force the flight path. You can't. You need the CombaR and the Grid—two modules you (hopefully) spent the last few missions securing—to even survive the approach to the Legacy.
Why Your Ship is Falling Apart
The core issue with the Starfield Port in a Storm sequence is the EM damage. Most ship builds focus heavily on ballistics or lasers, maybe a bit of shielding for dogfights. But the storm at Bannoc IV doesn't care about your auto-cannons. It bypasses traditional defenses. If you didn't install the CombaR (Conduction Grid) and the Decryption Module during the previous quests with the Crimson Fleet and UC SysDef, you are basically flying a toaster into a microwave.
You've got to make sure those modules are actually attached to your ship. I've seen so many people forget to go into the Ship Builder at the Key or a major port to physically snap them onto the hull. Just having them in your "inventory" or "quest log" does nothing. Check your ship's stats. If you see your systems flickering the moment you jump into the Bannoc system, you've missed a step in the shipyard.
It’s a long haul to the Legacy. You’ll be flying through a soup of green and orange clouds, and the visibility is garbage. The game wants you to follow the signal fragments. It’s sorta like a high-stakes game of "Hot or Cold." If you stray too far from the projected path, the EM damage ramps up exponentially. You'll hear that screeching alarm—the one that makes your heart rate spike—and then your engines will cut out. If your engines cut out in the middle of the storm, it's usually game over.
Finding the Legacy
Once you actually clear the storm, you’ll find the Vault Ship, the Legacy. It’s huge. It’s also ancient and creepy. This is where the mission shifts from a flight sim into a dungeon crawl. The atmosphere inside is oppressive. You’re looking for Jasper Kryx’s credits—the legendary haul that the Fleet has been obsessed with for decades.

Walking through the Legacy feels different than other abandoned outposts. There’s a lot of environmental storytelling here. You’ll find slates from the crew as they realized they were trapped. It’s dark. Bring a flashlight or, better yet, use the "Sense Starstuff" power if you’ve been hitting the Artifacts hard. It helps highlight the combat bots and turrets that are still active despite the ship being a graveyard for a century.
The gravity is weirdly inconsistent. Some rooms have it; some don't. You'll find yourself boosting over gaps only to realize the ship is literally tearing itself apart under the pressure of the storm outside. Keep an eye on your oxygen. The "Port in a Storm" mission is notorious for having long stretches without benches or places to wait, so if you're carrying too much loot (which, let's be real, we all are), you're going to be wheezing by the time you reach the vault.
The Vault and the Big Decision
When you finally reach the vault, the scale of the "treasure" is actually impressive. We’re talking millions of credits. But the mechanics of downloading the data are what trip people up. You have to manually flip several switches to reroute power. There’s a specific sequence, but the game is pretty good about marking the terminals. The real stress begins after you hit the transfer button.
The ship starts to explode.
Seriously. You have a limited window to get out. The "Port in a Storm" escape is one of the few times Starfield actually feels like a high-octane action movie. The path you took to get in is now blocked by fires, debris, and structural collapses. You have to follow the blue quest markers religiously. Don't stop to loot the dead bodies of the crew now. Just run. If you get turned around, look for the yellow emergency lights; they usually point toward the airlocks.

Picking a Side: UC SysDef vs. Crimson Fleet
This is the moment. After you escape the Legacy and survive the storm a second time, you have the credits. You have the power. You have to decide where to jump. Do you go back to the Key and hand over the money to Delgado? Or do you jump to the UC Vigilance and give it to Commander Ikande?
If you side with the Fleet:
- You keep access to the Key’s vendors (the best in the game for selling stolen goods).
- You get a massive payout.
- You have to kill a bunch of UC soldiers.
- You keep the "pirate" lifestyle, which makes most of your Constellation companions (like Sarah or Sam) absolutely hate you.
If you side with SysDef:
- You wipe out the Crimson Fleet.
- You get a cool uniform and a sense of moral superiority.
- You lose access to the Key’s unique ship modules and vendors.
- Your companions will generally approve, giving you those sweet "Sarah liked that" notifications.
Most players find the Fleet's rewards better for gameplay, but the guilt of betraying the "good guys" is real. Honestly, I usually keep a save file right before the jump just so I can see both endings. The space battle that follows is massive—one of the biggest in the game—so make sure your ship is actually combat-ready, not just "storm-ready."
Troubleshooting the Bannoc IV Jump
If you’re still dying in the storm, check your power distribution. This is a pro tip: dump all your power into Shields and Engines. You don't need Grav Drive power once you're in the system, and you certainly don't need Weapons power until you reach the Legacy or leave it. Maxing out your Shields gives you a much larger buffer against the lightning strikes.

Also, check your hull integrity. If you went into the mission with 50% hull because you forgot to repair at the last shipyard, you're making it way harder on yourself. Use "Ship Parts" (the heavy 10-mass items) mid-flight if you see your health bar dipping into the red.
Essential Prep List for Port in a Storm:
- Install the Conduction Grid (CombaR).
- Install the Decryption Module.
- Bring at least 10 Ship Parts for emergency repairs.
- Empty your personal inventory so you aren't encumbered during the escape.
- Upgrade your Reactor to at least Class B so you can power your shields and engines simultaneously.
The Starfield Port in a Storm mission is the ultimate test of your ship-building and navigation skills. It’s the point of no return for the game’s best faction line. Once you finish the escape, the galaxy is going to look a lot different depending on who you give those credits to.
Next Steps:
Before jumping to Bannoc IV, visit the Ship Services Technician at The Key. Go into the Ship Builder, select "Add," and navigate to the "Equipment" tab to verify both the Conduction Grid and CombaR are physically attached to your ship's exterior. Ensure you have at least 4 pips of power available for your engines to maintain the speed necessary to outrun the EM pulses during the final escape sequence. Once docked at the Legacy, prioritize speed over combat; the ship's internal security is secondary to the ticking clock of the hull collapsing.
