Dialogue (Subnautica)

Dialogue in-game is the act of someone (or something) talking. In Subnautica, there are many times where Dialogue will occur.

Below are two lists: one containing all dialogue that is currently used and in-game, with the other containing all cut and unused dialogue.

Trivia
Dialogue
 * 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.
 * However, this may not be true due to the fact than in Subnautica: Below Zero the pda refers to "the snowfox derby of 2342." as a past event, meaning that Subnautica: Below Zero takes place in at least 2343, therefor making it so the events of the original Subnautica take place in at least 2341.
 * Old dialogue from the PDA indicated that originally, instead of the player needing to disable the Quarantine Enforcement Platform, the player needed to forcefully change the atmospheric composition of the planet in order to disperse an energy field in the stratosphere. It is implied that this energy field is the reason the Aurora crashed, likely causing the referenced electromagnetic pulse mentioned in the scan conducted on the Aurora.
 * Several lines of old dialogue reference the fact that the Aurora was originally intended to be a mining and habitation vessel, tasked with ensuring the habitability of a planet prior to the colony ships arriving. As mentioned in a line of dialogue offering a mission briefing, the player is intended to disperse the aforementioned energy field in time, so that the colony ships heading to Planet 4546B don't suffer the same fate as the Aurora.
 * Old Seamoth Dialogue indicates that the Seamoth may have been planned to be able to flood, as well as be repaired and drained, similar to the cut mechanics of the Cyclops.
 * 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.
 * During early development, the Cyclops went through a voice change, going from a more text-to-speech style to a more human-like feel.
 * Obraxis Prime is an Easter Egg, referring 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.
