The Radio is an item that can be constructed with the Habitat Builder. One is also found in Lifepod 5, but it needs to be fixed with the Repair Tool in order to function.

OFFICER KEEN: This is Officer Keen in Lifepod 19! The captain is gone. I have assumed command.
The last thing the captain did was give me co-ordinates for dry land. We regroup one and a half kilometers south-west of the crash site.
Stay together. Good luck. This message will now repeat.

Come get us already!"

We're close to the crash site so bring radiation protection. 4, out."

Message Number Dialogue
RadioIcon.png Message 1

"This is Avery Quinn of trading ship Sunbeam. Aurora, do you read? Over.
Nothing but vacuum. These Alterra ships. They run low on 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 our assistance? Over.
I'll try them again tomorrow. Damn charter's going to have us blowing our credits running errands for Alterra. See what the long-range scans pick up in the meantime. "

RadioIcon.png Message 2

"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."

RadioIcon.png Message 3

"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 good 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."

RadioIcon.png Message 4

"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."

Alright tell Becky I'll just take the regular.

Just tell her the regular dude.
*Offmic* If I say regular, and she's like "what's the regular," I have to come all the way back up here.
The code should be 2679.
The regular's just a ham and cheese.

Ham and cheese!
*Offmic* Ok."



  • The Radio was originally named the Communications Relay.
  • Captain Hollister is a reference to the British TV Series "Red Dwarf (1988)".
  • The automated bounceback from the Aurora is most likely based on the position and condition the ship is in. Considering all the crew are dead and the ship is destroyed, it reaches the maximum arrival time (99999 hours) and cuts off.
  • Second Officer Keen assuming command may be a reference to the DOS computer game series "Commander Keen".
  • The line: "CPU: This is an automated bounce back from the Aurora. Divers equipped with seaglide personal propulsion vehicles will be dispatched to your location. *Static* Estimated arrival time: 9...9...9...9...9 hours.", is a possible reference to Portal 2, where the announcer says to Chell: "You have been in suspension for nine, nine, nine, nine, nine... nine, ni-- *continues in background* This courtesy call is to.....".
  • The messages "▀▖┗▛Nine new biological subjects designated. Mode ▄▖▜▚┣: hunting/analyzing. Sharing subject locations with other agents." and "▀▖┗▛Subject 11783 destroyed. Mode ▄▖▜▚┣: patrol. New targets unaccounted for: 1." are broadcasted by Warpers.

  • The radio message from Alterra H.Q. is voiced by two Youtubers from the "Neebs Gaming" channel, a channel which did a Subnautica roleplay series.
  • When the Radio was first released instead of messages it would send the player parts of lyrics from the song Holy Diver by Ronnie James Dio
