As a veteran player with over 200 hours exploring the oceans of 4546B, I‘ve uncovered all the secrets hiding within the vast flooded corridors of the Aurora colony ship. When that first flaming chunk of metal came screaming down from the sky, I knew there must be answers inside about this watery alien world.
Navi.
But the Aurora does not give up its secrets easily. Hazardous environments, sealed doors, and unearthly creatures defend the valuable blueprints and data logs entombed on the ravaged ship. Only the bravest divers can survive long enough to pry loose the codes that unlock access to these restricted zones.
In this complete guide, I‘ll share exclusive insight on exactly how to find every Aurora door code and what exotic rewards you can unlock within. You‘ll soon be fully prepared to launch your own daring mission into the Aurora to start fabricating advanced submarines back at base using the blueprints secured inside!
Let‘s get started! Here‘s everything you need to know:
Aurora Background & Lore
Before chasing door codes, it helps to understand the full history of this iconic Subnautica location:
Owned By: Alterra Corporation
Purpose: Interstellar colony ship deploying Phasegate portal
Route: Earth to planet 4546B
Fate: Shot down by energy pulse from The Quarantine Enforcement Platform
The Aurora was a massive colony ship sent on a long voyage through space to construct an interstellar Phasegate to instantly link Earth to planets light years away. This Phasegate was the first step in establishing deep space colonization all over the galaxy.
But shortly after entering orbit of 4546B, an energy pulse fired from the planet‘s mysterious "Quarantine Enforcement Platform" rips through the ship‘s hull, causing catastrophic structural failure. The Aurora crashes violently into the ocean of 4546B, ripped into several large sections strewn with debris.
We now know this "Quarantine Enforcement Platform" weapons system activated automatically to prevent the Aurora, perceived as an infectious alien ship, from landing on the planet and spreading a dangerous bacteria called the Kharaa. This Kharaa bacterium ravaged lifeforms on 4546B in the past before the precursors who built the Platform died out.
But why does 4546B now lie completely devoid of sentient life yet teeming with exotic ocean creatures? What wiped out its advanced precursor race? And what other technological relics remain down in the abyss?
The answers lie scattered and hidden within the flooded ruins of the Aurora…
Now let‘s uncover the secret codes that give access to those answers!
How To Access The Different Aurora Sections
The massive Aurora wreckage is spread across a large area on the ocean floor. For navigation purposes, the main accessible sections are:
- The Hull
- The Drive Section
- The Cargo Bay
Here is how to safely enter each area:
The Hull Access Point
Just swim up to any exterior side of the Aurora‘s rear half and you‘ll spot several massive breaches in the hull from catastrophic structural damage. The largest rectangular hole near the stern allows easy access inside the ship interior.
Within the deserted corridors, expect emergency lighting flickering off severed power cables. The stale air smells of dead fish and the metal walls groan from ocean compression. Stay alert once inside…strange sounds seem to echo from the rear of the ship.
The Drive Section Gateway
Make your way 200 meters along the exterior hull toward the broken front half of the Aurora to reach the exposed drive section flanked by gigantic ion engines.
A massive impact crater here leads down into the engineering bay. But deadly radiation from the cracked reactor core leaks out. Don‘t enter without a Radiation Suit! Glowing green columns of radioactive smoke billow up to obscure your vision. And beware the ominous reverberating roars rising from the darkness…
The Flooded Cargo Bay
Lastly, the cargo bay lies nearly detached from the main hull, deeper on the seafloor and accessed via a waterlogged cargo tunnel snaking up from a sealed watertight door.
Once inside through the narrow passage, the main cargo bay area is eerily quiet, with random loose crates floating about. But keep your seamoth‘s exterior lights on. Strange pale snake-like creatures hide in the walls and drop down onto passing divers…
So those are the three key sections requiring codes for further access. Read on to find exactly where to locate each all-important Aurora door passcode!
Every Aurora Door Code & Password Location
The Aurora holds four hidden numeric codes needed to open all its security-sealed compartments. Their locations:
#1 Cargo Bay 3 Door Code: 1454
This code unlocks optional Cargo Bay 3 off the main vehicle bay. To find it:
Enter the hull and search the small Captain‘s Quarters room just left of the yawning main cargo entrance. Check the personal Captain‘s computer on the desk to discover the passcode 1454 for Cargo Bay 3 access.
Grab it! This bay offers resources like titanium, computer chips, and battery charger fragments you can scan back at base.
#2 Crew Cabins Door Code: 1869
You‘ll also spot a Crew Manifest PDA in the Captain‘s Quarters referring to passenger cabin access. To get this door code:
Use the previous 1454 code to unlock Cargo Bay 3. Inside, check random wall lockers to eventually locate the misplaced Crew Manifest scanner file. Sync to receive the 1869 crew cabins access code!
The crew cabins lead down through eerily deserted bedrooms towards the sealed drive section doors deeper inside. Keep going!
#3 Drive Section Access Code: 2679
This elusive code unlocks the drive section doors to proceed inward to the Flight Deck and Reactor Core.
To find it: navigate using previous codes down through the crew cabins until you reach very rear of the ship by the massive Engine Ion Crystal. There an unpowered automatic door blocks your way. But on the wall nearby you‘ll spot an Emergency Docking Access panel flashing.
Interact with it to hear the final logged commands of Aurora‘s tragically doomed Captain Hollister. His last transmission captures the sound of the alien energy pulse striking the bridge.
Listen carefully to Hollister‘s log audio during the alien attack. In his final seconds, he desperately shouts out the drive section access code "2679" into the radio! Memorize it quick…that unlocks the blockage to finally enter the deadly radioactive area ahead.
You now have what you need to break into the highly irradiated drive section filled with valuable engine fragments and the ship‘s main computer data core. But one last path remains blocked…
#4 Lab Facilities Access Code: 6483
After braving the radiation leaks and cave crawlers lurking inside the gloomy drive section corridors, take repair tool in hand to cut open the large high security sealed door labeled "Deck Access – Science Labs/Aquarium".
In the newly opened laboratory room just inside, head right from the entry and check the alien specimen testing desk. Next to a massive shattered stasis tube lies one last PDA printout showing lab access code 6483.
Sync it to memory! Now you can unlock the labs with critical Prawn Suit and Vehicle Modification Station fragments at last. Not to mention some secret precursory discoveries…
So those are the locations to retrieve all 4 essential Aurora access codes. Now let‘s analyze the goodies stashed behind each barrier!
Blueprints & Gear Hidden Behind Every Barrier
Enduring all hazards to enter restricted zones allows you to secure some fantastically valuable material and data. Here‘s what lucrative tech you can scan once through:
Cargo Bays 1-3: Seamoth Fragments
Crucial to craft your own quick and nimble Seamoth submarine, blueprint fragments for the titanium co*ckpit shell, aerodynamic hull plating, and modular engine components are scattered everywhere throughout the cargo bay.
Once mended together after enough scanning at the blueprint fabricator, the rugged little Seamoth grants greatly expanded deep sea exploration range to uncover further crash sites. You‘ll rely on this hardy submersible the entire game.
Drive Section: Modification Station & Prawn Suit
Deeper inside past radioactive contamination leaks, the high security drive section grants access to both a hulking wheeled Prawn exosuit and a futuristic Modification Station for upgrading all gear.
The modular Prawn blueprints enable building a heavy-duty bipedal mining mech to safely harvest resources in hostile ecosystems. And the mod station allows adding special upgrades onto existing equipment like extra tank storage onto oxygen kits.
Science Labs: Vehicle Modification Console
Towards the very front limits of the Aurora, the final unlocked science labs guard perhaps the most valuable reward of all:
The Vehicle Modification Console
This fabulously advanced (and massive) fabrication machine unlocks crafting upgrades for every type of submersible like torpedo or sonar modules for the Seamoth and reinforced armor attachments for the PrawnSuit.
Having these high-tech modules installed in your underwater fleet makes exploration dramatically safer and faster. You‘ll spend much time here bolting on upgrades before ambitious deep sea missions in alien architecture and precursor facilities.
So in summary:
- Cargo Bay: Seamoth Submarine blueprints
- Drive Section: Prawn Suit blueprints + Modification Station blueprints
- Labs: Vehicle Modification Console blueprints
As you can see, keeping up courage during the suspenseful hunt to gather every last Aurora code pays off exponentially back at base once you unlock constructing these big ticket technologies for yourself.
Now let‘s prepare you for surviving all lethal obstacles the Aurora will assuredly throw at you!
Hazards & Defense Strategies
The long-dead carcass of the Aurora hides many perils for scavenging explorers:
Fortunately, packing the right protective equipment and understanding critical environmental hazards makes surviving this spacecraft graveyard possible:
Hazard #1: Intense Radiation & Fires
Once you pass deactivated metal bulkhead doors to enter the broken front half of the ship, leakage from the ruptured nuclear drive core will bombard unprotected divers with intense gamma radiation that quickly devours health.
Likewise, electrical fires smoldering in mountainous piles of blackened wire debris lining passageways rapidly drain oxygen levels.
Defense: Reinforced Dive Suit + Extinguishers
Equip a Reinforced Dive Suit or Radiation Suit to reflect dangerous radioactive energy, while carrying 1-2 fire extinguishers lets you douse blaze blockages. Don‘t forget medkit packets and food for healing radiation damage.
Hazard #2: Hull Breaches & Flooding
Numerous explosions blew massive holes in the Aurora‘s hull, causing compartments to flood. A careless swimmer can easily get sucked out into open ocean through a random wall gash.
Defense: Repair Tool + Hull Cameras
Use a Repair Tool‘s metal welding sparks to seal minor interior wall breaches temporarily, blocking water ingress. Install external hull cameras on your docked Seamoth to safely spot outer threats first.
Hazard #3: Cave Crawlers & Crashfish
Pale, eyeless, snake-like Cave Crawlers swarm darkened passageways and cargo storage rooms inside the Aurora, attacking from crawling out of ventilation ducts or wall cracks.
Defense: Sonic Deterrents + Creature Decoys
Equip perimeter defense sonar modules on your Seamoth to disrupt Cave Crawlers before they swarm. Launch decoys towards lone Crashfish to trigger their explosives from safe distance.
Hazard #4: Disorientation & Panic
Navigating decrepit corridors prowled by shrieking monsters can quickly turn disorienting, causing blind panic attacks inside cramped rooms when oxygen runs low.
Defense: Flares + Survival Training
Always drop flares to mark door lock locations and critical rooms for the return trip out. Meditative mental preparation is key before any deep dive.
Follow those critical threat avoidance tips and the Aurora will prove less dangerous than it first appears.
Now prepare your gear and let‘s uncover what really happened to the lost crew!
Cracking The Tragedy of the Aurora
Each unlocked section unleashes more disturbing clues about the doomed vessel‘s failure:
The sealed drive core logs show Captain Hollister growing increasingly desperate as asteroid storms in orbit and quarantine platform energy pulses ruthlessly battered his ship…yet still he refused evacuation orders from corporate HQ — obsessed with completing his mission…
Blood traces on lab instrument panels point to whether some scientists survived the crash initially…only to meet their demise to radiation, starvation, or something more sinister?
Even the codes themselves form a thought-provoking pattern: 1454-1869-2679-6483 …almost like coordinates leading down into the depths? Or perhaps the numbers link mathematically to crack a deeper mystery?
Indeed, many coded clues hide within PDAs, blackbox recordings, and the very structure of the Aurora itself…all challenging you to deduce what truly happened in the crew‘s final terrifying moments.
Can you unravel the entire truth? Get in there and find out!
Just take care not to become another vanished soul among the wreckage yourself…
In Closing: Brave The Aurora!
Hopefully this guide has fully prepared you to launch your own mission penetrating the Aurora‘s veils of water, fire, radiation, and darkness guarding its coveted blueprints and PDAs.
Although intimidating at first glance, locating all door passcodes methodically while properly equipping hazard defenses will guarantee your success. And the priceless high-tech blueprints found within for constructing powerful new submarines and upgrade modules back at base make the treacherous journey deeply rewarding.
Each small step forward to unlock the next barricade solves another portion of the puzzle about the Aurora’s catastrophic fate. Dogged persistence pays off!
So gear up, load your scanner…and get inside there to seize the future tech capability needed to explore this fascinating alien ocean even deeper! The alluring call of those flooded decks and forgotten laboratories awaits. dare you enter?
