Sunbeam Pre-Arrival Dialogues Received 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, we're 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 our assistance? Over.

I'll try them again tomorrow. See what the long-range scanner picks up in the meantime. Damn charter'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? The last time I parked a rig this big on a rock that small was in VR, and I blew it
Oh, it's a bad option alright, but so are all the others.
3rd Message Day 19 This is Sunbeam. Y'know, Aurora, we're from a little trans-gov on the far side of Andromeda, and we have a saying there.
There's no bad without the good, no god without the bad.
Sounds like you tasted a bunch of the former, but that only means you're overdue a whole lot of the latter.
Might just be we're it.
We're scanning for somewhere to park as we speak, we'll be in touch when we find it. Sunbeam out.

4th Message Day 21 Aurora, we're approaching the planet now, and we have a landing site for you that's... well, it's better than the alternatives.
We've sent you the coordinates.
It'll take us a couple of days to align our orbit, we should be able to establish direct contact with you during that time, then we're coming in to get you.
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

"Survivor, we see you!
Man, I don't know how you held out down there.
We've broken atmosphere and we're descending towards the landing site.
Is that a building down there?! What do you mean you can't identify it?
Hold on, no turning back now *Static*
Positions everyone, touching down in 10, 9, 8-
It's coming from the building?! Change course, set thrusters to (full)- *Static*

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.

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.
