Habitat Compartments

Log-128 Alien Containment "Aquariums provide an ideal opportunity to study alien fauna up close.

Log-128 Multipurpose Room "It may be prudent to separate work and leisure spaces to maximize productivity.
Treat this space as your home, but never forget that it is not."

Log-128 Cooked Peeper "The fabricator cooks small organisms, while disposing of the skeletal structure, bodily fluids and internal organs, thus rendering them safe for human consumption."
Log-128 Disinfected Water "Preparing the day's water ration, ahead of time, will help ensure against dehydration, and eventual death."


Log-128 Blood Kelp Zone "This ecological biome matches 7 of the 9 preconditions for stimulating terror in humans."

Sunbeam Pre-Arrival Dialogues Recieved on Day Dialogue
1st Message Day 9 This is Avery Quinn of trading ship Sunbeam. Aurora, do you read? Over.

Still nothing. These Alterra ships. They run out of engine grease, they send an SOS; you offer to help, they don't pick up.

Aurora, I'm out on the far side of the system, it's going to take more than a week to reach your position, do you still need out assistance? Over.

I'll try them again tomorrow. See what the long-range scanner picks up in the meantime. Damn chater's going to have us wasting our profit margin running errands for Alterra.

2nd Message Day 13 Aurora, this is Sunbeam again. We just picked up a massive debris field at your location. I didn't know how bad... How many of you... I didn't know.'We are now en route to your location. We're going to bring you home. Sunbeam out.

What else can I say? We're a six-seater and we aren't even slightly equipped to handle this? Our pilot last attempted a planet landing in the academy simulator?

It's a bad situation, but so are all the alternatives.

3rd Message Day 19 Sunbeam, broadcasting to all survivors of the Aurora. We've covered more than half of the distance, so hold on in there.'We're scanning the planet for dry land as we speak. You couldn't have picked a less convenient parking spot, but we'll be in touch as soon as we have a landing site for you. Sunbeam out.
4th Message Day 21 Aurora, it's Sunbeam. We've made orbit, and scans have found a landing site on the planet that's only rated hazardous. It's our best shot. We've sent you the coordinates. We'll be there in two days' time. Cross your fingers the weather holds, and don't leave us waiting. Sunbeam out.

Sunbeam Arrival

Conditions to meet


Log-128 Player is present at Quarantine Enforcement Platform "PDA: Attention - Patching in a local broadcast from the Sunbeam.
I don't believe it, there's someone down there!

Aurora survivor, we have your PDA signature!
I don't know how you walked away from that wreck, let alone survived since then, but we're happy to let you onboard and hightail back to federation space.

Stand back, we're approaching the landing site now. Breaking atmosphere in 5... 4... 3... " *Static*

"What is that?! No, the RED spike.

From the planet?!" *Explosion*

Log-128 Player is absent at Quarantine Enforcement Platform "PDA: Picking up orbital transponder signature of trading vessel Sunbeam.
Vessel is approaching planet surface and initiating surface scanning procedures.
Detecting massive power surge from anomalous contact. Energy discharge detected.
Vessel signature lost."

Player disables the Quarantine Enforcement Platform before Sunbeam arrives

"Aurora survivors, this is trading ship Sunbeam.
We've tracked your distress signal, but your ship's left a giant debris field up in orbit, we can't attempt a landing.
We're gonna have to head home.
We'll send our data to Alterra as soon as we can. Hold on in there. Sunbeam, out."

  • Due to the fact the AI at the beginning used to say "In the late 22nd century...", Subnautica is believed to take place between 2160-2199. This message can be played below.
    Old Intro
  • There are different voices speaking in certain dialogue, the voices change depending on where the player is. ex: The Standard female voice is there most of the game, but in a Seabase, Seamoth, Prawn Suit, and Cyclops the voices change. This may be due to the fact the player fabricates computer chips for all of these things, so it is possible computer chips contain AI's.
    • However, this may not be true, due to the fact that many other items are used with computer chips but they do not have their own AI.
  • Obraxis Prime is a reference to one of the Subnautica developers, Scott "Obraxis" MacDonald.
  • "You've been down too long in the midnight sea.", was a reference to the song Holy Diver by the US heavy metal band DIO. This text was removed from the game.
