If you’ve spent any time poking around the wreckage of the Aurora in Subnautica, you’ve probably stumbled across locked cabin doors that hold valuable loot, crafting schematics, and small lore snippets that fill in gaps of the ship’s final hours. Learning how to get into cabin 2 in Subnautica is one of the most rewarding small exploration goals for early to mid-game players, as it holds a high-capacity storage upgrade and a personal log from one of the Aurora’s crew members. I remember spending nearly an hour running up and down the Aurora’s hallways my first playthrough, missing the key entirely because I rushed past a small storage crate in a flooded corridor. This guide breaks down every step you need, no guesswork required.
Prerequisite Gear You Need Before Heading to Cabin 2
You can’t even get close to Cabin 2 if you don’t have the right gear to survive the Aurora’s hazards first. I always recommend gathering all these items before you launch your exploration run, so you don’t have to turn back halfway because you ran out of oxygen or got mauled by a cave crawler. You can skip non-essential items like extra food or water if you’re in a hurry, but these four core pieces of gear are non-negotiable.
- Radiation suit: The Aurora’s wreckage still emits high levels of radiation until you repair the drive core, so this is non-negotiable. Don’t skip the radiation helmet and gloves either, or you’ll take continuous damage the second you get within 50 meters of the wreck.
- Repair tool: You’ll need to cut through at least one blocked door and seal a few bleeding radiation leaks if you want to access the crew quarters wing where Cabin 2 is located. Keep at least two full batteries for it, just in case you run into extra blocked doors along the way.
- High capacity O2 tank: Large sections of the Aurora’s lower decks are flooded, and you’ll spend at least 10 minutes underwater navigating twisted corridors before you reach the dry crew quarters section. A standard O2 tank won’t give you enough time to explore safely, especially if you stop to pick up extra salvage.
- Stasis rifle or survival knife: Cave crawlers and bleeders are scattered all over the Aurora’s interior. A stasis rifle is better for keeping groups of crawlers at bay, but a sharp knife works fine if you’re comfortable with close combat and want to save inventory space.
You can skip bringing a lot of extra storage if you’re only heading for Cabin 2, but I usually bring an extra small storage crate to stow extra salvage I find along the way. The Aurora is packed with scrap metal, lithium, and wiring kits that you can use for late-game crafting, so it’s worth picking up any extra resources you see if you have space. I once found three free diamond chunks sitting in a broken supply crate near the janitor’s closet on one run, which saved me hours of searching for them in the Deep Grand Reef.
Step-by-Step: How to Get Into Cabin 2 in Subnautica
Once you have all your gear together, head to the front entrance of the Aurora, located on the ship’s starboard side, near the large array of broken antennae. Swim through the flooded entrance corridor until you reach the first set of dry stairs, then climb up to the main deck level. You’ll see a few cave crawlers milling around the entrance, so take them out quickly before they get a chance to jump you.
From the main deck, follow the signs labeled “Crew Quarters” down a narrow, partially flooded hallway. You’ll have to repair a blocked door with your repair tool about halfway down the hall, so keep an eye out for the glowing red door control panel on the wall to the left. Once you get through that door, you’ll enter the main crew quarters common area, with multiple small cabin doors lining the walls and a few broken vending machines scattered across the floor. You can hit the vending machines with your knife to get free nutrient bars if you’re low on food.
Cabin 2 is located on the far left side of the common area, near the broken water fountain. You’ll notice the door is locked, with a small key card slot next to the handle. Don’t waste time trying to cut through the door with a laser cutter – it won’t work, and you’ll just waste valuable battery life. You need the specific Cabin 2 key card to open it, which is hidden in a nearby corridor.
Turn around and head back down the hall you came from, then take the first right turn into the unmarked janitor’s closet. The key card is sitting on top of a metal storage shelf in the back of the closet, next to a stack of cleaning supplies and a first aid kit. Grab the key, head back to Cabin 2, and swipe it at the panel to unlock the door. That’s all there is to it.
Pro tip: If you accidentally drop the key or lose it before you unlock the door, it will respawn back in the janitor’s closet after about 10 in-game minutes, so you don’t have to start a new save if you make a mistake. I learned that the hard way my first playthrough, when I dropped the key in a flooded section and couldn’t find it again for 45 minutes.
What Loot and Lore You’ll Find Inside Cabin 2
Cabin 2 isn’t just a random empty room – it’s packed with useful items that make the entire exploration run worth your time, even if you don’t pick up any other salvage from the Aurora. I always make a point to hit this cabin first every time I start a new playthrough, because the storage upgrade cuts down on how many trips I have to make back to my base early on.
The most valuable item in the room is the High Capacity Storage Upgrade for your personal inventory. This upgrade adds 12 extra slots to your backpack, which is a game-changer for long exploration runs to the Lost River or Lava Zones later in the game. You’ll find it sitting on the desk next to the bed, in a small white equipment case. You can install it immediately by opening your inventory and dragging it to the upgrade slot on your suit.
You’ll also find a personal log from the cabin’s occupant, a crew member named Sam Ayou, that talks about her concerns about the ship’s secret mission and the Degasi crew that went missing on the planet months before the Aurora crashed. These small logs add a lot of depth to the game’s story, and collecting all of them unlocks a small hidden lore scene at the end of the game if you’re a completionist. I still get chills reading some of the later logs, even after playing through the game half a dozen times.
There’s also a first aid kit, two nutrient blocks, and three bottles of filtered water stowed in the cabinet under the bed, which are perfect for topping up your health and hunger levels before you head back out to explore the rest of the Aurora. I usually leave these items here if I don’t need them, so I have a safe stash I can come back to later if I get hurt while exploring the drive core section. You’ll also find a small supply crate under the desk with a free diamond and two lithium ingots, which are essential for crafting the depth modules you need for your seamoth.
Common Mistakes to Avoid When Trying to Access Cabin 2
I’ve talked to dozens of other Subnautica players who’ve struggled to get into Cabin 2, and almost all of them made the same small mistakes that delayed them for hours. Avoid these pitfalls, and you’ll be in and out of the cabin in less than 20 minutes total. If you follow all these steps, you won’t have to waste hours searching for how to get into Cabin 2 in Subnautica like I did my first run.
The most common mistake is rushing past the janitor’s closet without checking it. The closet is unmarked, and the door is slightly ajar, so it’s easy to miss if you’re sprinting down the hall looking for the crew quarters. Make sure you check every unmarked door you pass as you navigate the Aurora’s hallways, because most of them hold valuable loot or key items you need for other quests. I once found a free stasis rifle in an unmarked storage closet on my second playthrough, which saved me the hassle of crafting one myself.
Another common mistake is trying to access the crew quarters before you repair the radiation leaks in the lower decks. If you don’t seal those leaks first, the entire crew quarters section will be flooded with radioactive water, and you’ll take continuous damage even while wearing a radiation suit. Always repair the leaks first before you head to the cabin, or you’ll have to turn back halfway.
Don’t forget to check under the desk in Cabin 2 before you leave, either. A lot of players miss the small supply crate under there that has a free diamond and two lithium ingots, which are essential for crafting the depth modules you need for your seamoth later in the game. I missed this crate my first three playthroughs, and I only found it when I was cleaning out the cabin for a base build challenge I was doing with friends.
Finally, don’t leave the Aurora immediately after you leave Cabin 2. The crew quarters wing has three other locked cabins that hold even more upgrades and lore logs, all of which use key cards hidden in nearby rooms. It’s worth taking an extra 30 minutes to explore the entire wing while you’re already there, instead of having to make a second trip later. You’ll also find the blueprints for the prawn suit in the nearby cargo bay, which is one of the most useful vehicles in the entire game.
Exploring the Aurora can feel overwhelming at first, with all its twisted corridors and hidden hazards, but tracking down small, rewarding areas like Cabin 2 makes all the effort worth it. Now that you know how to get into cabin 2 in Subnautica, you can grab that valuable storage upgrade early in your playthrough and make every future exploration run far less stressful. Don’t forget to take your time as you wander the rest of the wreck, too – there are dozens of hidden secrets scattered throughout the ship just waiting to be found. You never know what useful loot you’ll stumble across next.
