Unknown This seems new

This article contains information that is updated for the latest Experimental Version of Subnautica. Players using stable mode may find this information inaccurate.

The Communications Relay is an item that is constructed with the Habitat Builder. One can also be found in Lifepod 5 which needs to be fixed with the Repair Tool in order to function.

Uses & MessagesEdit

After repairing the Communications Relay inside Lifepod 5, it will inform the player that it is broadcasting a distress signal:

  • "RADIO: Radio online. Greetings survivor. I am your emergency radio transponder. Broadcasting emergency distress signal."

Afterwards, the player will receive a message from the Aurora:

  • "RADIO: This is Aurora. Distress signal received. Divers equipped with seaglide propulsion vehicles will be dispatched to your location in 9...9...9... hours. Continue to monitor for emergency transmissions from other lifepods."

After this message has been answered, the player may receive more messages. Most of these messages are distress signals from other Lifepods, but the player will also receive messages from the Sunbeam in an attempt to get rescued.

Completion of certain tasks will trigger the following messages:

Lifepods Edit

Sunbeam Edit



"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 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 scans pick up in the meantime. Damn charter's going to have us wasting our profit margin running errands for Alterra."



"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."



"Sunbeam, broadcasting to all survivors of the Aurora. We've covered more than half 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."



"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."

Trivia Edit

  • 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. Whereas the announcer says to Chell: "You have been in suspension for nine, nine, nine, nine, nine... nine, nine *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 message "▀▖┗▛▄▖▜▚┣ ▜▚┗┣┗┫┓┏┓ ▛▄▖┅┗▖. ┣┗┏▛▄▖▜┏┣ ▚ ▖▞┣┗▖┗┣. ┣┗▖┃▀▚▗┏┏┓. ▖┛▀┗▞┃┏▄ ▛┏┗▄▖▜▚┣ ┅▖┗━▖ ▖┓┫▞┣ ▚ ▛▄┅┗▖ ▚ ▖▞┣┗▖┗┣ ▚┛▘▞━▖┅." is an automated message from a Precursor.
