Easter Eggs

Easter Eggs are hidden references to other games or pop culture.

Natural Selection 2

The Natural Selection 2 Poster

The Natural Selection 2 Poster can be found inside the Wreck in the Grassy Plateaus and in the Aurora, and can be placed inside any Seabase. There are many other objects from NS2 in Subnautica as well. Trello is a reference to another game made by Unknown Worlds.

Portal 2

The first message broadcasted from the Radio, which used to say: "This is Aurora. Distress signal received. An emergency relief team will be dispatched to your location in  9...9...9 *static* ...9...9 hours" Continue to monitor for other emergency transitions from other lifepods. The wait time is a possible reference to Portal 2, whereas the announcer says to Chell (the protagonist): "You have been in suspension for nine...nine...nine...nine...nine..."

Holy Diver

A fifth message is received by the player's Radio later in the game. The day this message is received varies. It displays: "You've been down too long in the midnight sea. Oh don't you see what I mean?" This message is a reference to the song Holy Diver by the US heavy metal band DIO.

Star Trek

The line occasionally said by the PDA after activating either Data Terminal in the Quarantine Enforcement Platform, "Resistance Is Fertile," is a spoof on the Borg's famous line from Star Trek, "Resistance is futile." Shortly after the PDA says this, jazz music will start to play. This Easter Egg was added by Simon Chylinski after Scott Thunelius jokingly suggested the interaction.

A video of this can be found here: https://youtu.be/ac4wlJoTowE?t=44s

Obraxis Prime

When the Player fabricates the Survival Knife for the first time, the Dialogue says: "Weapons were removed from standard survival blueprints following the massacre on Obraxis Prime.  The knife remains the only exception." Obraxis is a developer of Subnautica.

Strader VI

There is a Data Download mentioning the hive mind of Strader VI. Cory Strader is a developer of Subnautica.

China

In the Soundtrack to the Sparse Reef, there is an audio clip featured of Donald Trump saying "China". Listen closely to the song below at 1:18.

Starwhal

In the PDA dialogue for the Stasis Rifle as well as in one of Paul Torgal's journal entries, a creature called a "Starwhal" is briefly mentioned. "Farming Starwal eggs" is also mentioned in the Captan's Log.  This could be a possible reference to the game Starwhal where players must control flying narwhals with the goal to pierce each other's hearts with their horns.

Cyclops Greeting

There is a chance for the Cyclops AI to say: "You are the best captain on the planet, I'm not even squidding." when the Player has entered it, rather than its normal line. This refers to the Player being the only captain on the planet.

Future Perfect

Two Alien Relics, the Alien Rifle and Doomsday Device, are reused assets from the game Future Perfect, another game made by Unknown Worlds Entertainment. The Alterra Corporation is in this game and several others as well. It is not known if this is simply an Easter egg or an attempt to connect two games.

CHBClive

Found in Alien Relic 7. CHBCLive made Chinese translations since the farming update. He died battling cancer.
