Dialogue

In Subnautica, there are many times when dialogue will occur.

Here is a list of all dialogue in the game.

Prologue
"In the late 22nd century, humanity is beginning to colonize space. Before colony ships arrive, habitation vessels are appointed terraforming missions. The Aurora was once such a vessel. During it's descent, a mysterious energy pulse struck the Aurora,  resulting in catastrophic hull failure. A single life pod jettisoned prior to impact. You, were in that life pod."

Aurora
 Speech 1  "Scanning the Aurora. Zero Life signs detected. Lethal radiation levels detected. The main drive core has malfunctioned. The primary dark matter containment field has dropped at 36% amplitude. Continuing to monitor."

Speech 2
"Caution! Readings from the Aurora suggest erratic fluctuations in the primary dark matter containment field. A breach of the main drive chamber may cause a cascading quantum flux detonation."

Speech 3
"Warning! Readings from the Aurora exhibit characteristics consistent with total degradation of the dark matter containment field. Spikes in quantum fluctuations suggest an uncontrolled cascade detonation will occur with a probability of 83.5%."

Speech 4
"Emergency! Readings from the Aurora show severe instability in the primary drive core. The central dark matter reactor will reach a supercritical state in T minus 10, 9, 8, 7, 6, 5, (static) 4, (glitchy almost inaudible) 3, (half of the word said before being cut off by the explosion) 2."

"Hull integrity restored. Draining systems initiated."

(When Seabase or Cyclops is repaired)

"Welcome aboard Captain!"

Trivia

 * Due to the Fact the AI at the beginning says "In the late 22nd century" this game is believed to take place between 2145-2199.
 * This would explain the high tech items in the game.
 * There are different voices speaking in certain dialogue, the voices change depending on where you are. ex: The Standard female voice is there most of the game, but in a Seabase, Seamoth, 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.
