Subnautica Aurora Codes (2025) & Walkthrough: Hands Aboard!

Subnautica begins with the player character crash landing in the endless oceans of Planet 4546B. When the door of Lifepod 5 pops open and the player first peaks outside, they are greeted with miles upon miles of shimmering blue. And one landmark. Their crashed ship, the Aurora.

As soon as I gained control of my character, I only wanted to head straight toward the Aurora. It’s vast, it’s cool looking, and it’s tantalizingly close and yet just out of reach.

I’m sure the first time many players experience death in Subnautica, it’s trying to head to the Aurora before they’re ready. Thankfully, the Aurora doesn’t have to stay out of reach for too long. But you will need to be prepared.

So, carry on for our Subnautica Aurora codes and walkthrough with everything you need to know before you board.

What Is the Aurora?

The Aurora was a newly built Alterra Long-Range Capital ship. It was later sent to build a new PhaseGate in the Ariadne Arm. Unbeknownst to most of the crew, it was also on a secret mission to look for any survivors of the Degasi crew.

At the beginning of the game, the Quarantine Enforcement Platform, which protects planet 4546B shoots the Aurora out of the sky. The crew tried to escape but only one was successful, Ryley Robinson. It would appear all other hands were lost.

Subnautica Aurora Door Codes List

So, the door codes in Subnautica, what are they?

When exploring the Aurora, you’ll find doors that don’t need repairing and can’t be cut open. For these doors, you’ll need Subnautica key codes. They can be found in PDAs on the broader world and Aurora.

But let’s face it, finding these Aurora codes can be a major pain.

Luckily, you can find all Aurora’s codes below:

Robotics Bay: 6666
Lab Access: 6483
Cargo Bay: 1454
Code for cabin 1 Subnautica: 1869
Captain’s Quarters Code Subnautica: 2679

But stop right there! Before you rush in, you need to prepare yourself!

What’s Inside?

With the number of hoops you have to jump through just to get inside, you might ask yourself if it’s worth even going to the Aurora.

After all, it’s basically just a high-tech graveyard now, right?

First, the Aurora is a treasure trove of game lore. You’ll be spending a lot of time playing Subnautica so it would be nice to know what’s going on, right? The Aurora is full of PDAs that flesh out the world of Subnautica. You’ll find out more about Alterra Corporation and what life is like in the future.

The ship is also full of clever world-building through environmental storytelling. Especially once you get to the crew’s quarters. Plus, many of these PDAs contain Subnautica key codes, like the Subnautica Captain’s code.

Second, there’s loot, baby! The Aurora is chock full of loot. You will be doing more than one trip back and forth if you want to loot everything. We’ll start with the best loot first.

There are equipment and vehicle fragments everywhere. These include –

Propulsion Cannon fragments
Cyclops engine fragments
Seamoth fragments
Prawn Suit fragments

How useful you find these depends on how far into the game you’ve gotten. You’re likely to have the Seamoth and, perhaps, the Propulsion cannon already.

However, you’re unlikely to have the Cyclops or Prawn Suit yet. The Aurora also has a handful of helpful upgrade modules lying around.

These include:

Storage Module – Great for hauling around all the loot you found in the Aurora
Seamoth Depth Module MK1 Upgrade Module – Useful for late-game exploration
Cyclops Engine Efficiency Module – The Cyclops can be a thirsty girl. Anything that slows down the Cyclops’ power drain is a godsend.

The Aurora is also full of useful everyday items. It is littered with crafting materials, batteries, and consumables. You’ll probably find yourself doing repeat trips to grab everything.

Third, the Aurora has many excellent cosmetics you can use on your base. The minimalist/ hyper-modern style can make player-built bases feel a little stark. Thankfully, you can loot some cool posters and decorations from the Aurora that you can use to brighten up your floor.

Fourth and perhaps most importantly, visiting Aurora is vital to finishing the game. Eventually, you’ll need to escape Planet 4546B. The Aurora is obviously out of commission, so you’ll need a spaceship.

The blueprints for the Neptune Escape Rocket can be found in the Captain’s room.

I don’t think visiting the Aurora is opening up the end of the game, though. You’ll still need to build the rocket (not easy) and disable the Quarantine Enforcement Platform (definitely not easy.)

Preparing For Entry

As mentioned earlier, many players want to rush straight to the Aurora. However, doing so unprepared is a guaranteed way to become fish food. It’s not just a matter of finding the Aurora Subnautica codes and diving straight in. You’re going to have to slow down and wait a while.

The Aurora is primarily intact when the game starts, but the engines are leaking radiation. Unsurprisingly, radiation is harmful to you. So, you won’t get close until you find a way to protect yourself. Even worse, the Aurora is a ticking bomb. After a few in-game hours, it goes boom. Big Boom.

If you’re anywhere near it when this happens, you’re pretty literally toasted. Some players worry that the countdown given to you by the PDA means you only have a limited amount of time to get onto the ship and loot it before everything is lost.

Fortunately, the opposite is true. The game gives you a few days to get used to the game mechanics and gather everything you’ll need for your excursion to Aurora. We would advise you to have the following items –

Essentials

Radiation suit – Absolutely vital. The radiation coming from the ship will cook you before you even get close.
Repair tool – You’ll need this to access certain areas of the ship. Several damaged doors need repairing. Furthermore, It is needed for fixing up the drive room.
Laser Cutter – Again, this is needed for exploration. To access both the Prawn Suit room and the black box terminal, you’ll need to do some cutting.
A survival knife or thermoblade is essential. The ship is full of Bleeders and cave crawlers who only respect the pointy end of a blade.
Propulsion Cannon/ Repulsion Cannon – Some crate barriers can be dismantled using these two. The most notable obstacles are at the laboratory entrance and the main hallway.
Transport – A seaglide is super helpful for navigating the flooded areas of the Aurora, and you should already have one handy. The seamoth is also handy for getting to the Aurora and returning to base with all your loot.

Stasis Rifle – This is useful for dealing with the enemies inside the Aurora and out. However, it’s not essential if you haven’t got your hands on one yet.
Fire extinguisher – There is fire all over the Aurora that is blocking off access to some of the better loot. You can use an extinguisher to put them out.
One or two batteries – There are some loot-able batteries on the ship. However, you don’t want to rush and run short on juice.
A little food– İt can be a long journey to Aurora and back. While there is food and water available on the ship, if you’re worried about running short, take a little food to be safe.
Medkit – Again, there are a couple on the ship. However, better safe than sorry. There are a lot of enemies around here.

Subnautica: How to Get Into The Aurora

First, you’ll have to wait for the ship to explode. If you attempt to cheat your way onboard with Subnautica codes, it won’t work. Teleporting to the Aurora before she blows will trap you in a buggy hellscape.

There are two roots inside.

You can approach the torn-up front section on the right side of the shore area. There is a gap behind a floodlight you can enter through. It’s blocked by crates, so you’ll need the Propulsion Cannon. This leads you straight to the laboratory.

Or you can use the ramp and enter through the main corridor. This is my preferred route. Just be aware that Leviathans patrol the exterior of the ship.

You’ll have to creep past if you don’t have the Stasis Rifle. A good tactic is to sneak up to the ramp with the sea moth and then park so the moth is blocking the ramp. This should stop you from getting any unwanted Leviathan visitors.

Conclusion

Subnautica is full of exciting points of interest, so check out other excellent games like Subnautica. Caves, alien monuments, crashed pods, and bases are all over the place, ripe for exploration. But personally, my favorite area is the Aurora. I just love it for its environmental storytelling—and of course, loot.

It can be a bit of a maze, and unfortunately, there is no Aurora map in Subnautica but exploring is half the fun. Hopefully, you find the above guide useful so that you can get exploring as soon as possible.

Just remember, horrors lay beneath, so go prepared.
