This article is for the PC version of Stellaris only.
There are two types of species that did not achieve FTL in the game: pre-FTL civilizations and pre-sapient species. They can be made plentiful or outright disabled via the galaxy generation options.
Pre-FTL civilizations are civilizations that have yet to develop the technology necessary for interstellar space travel. They advance through multiple ages as their history is written and can become full-fledged interstellar empires if they are technologically enlightened by another spacefaring empire or left alone enough to develop on their own. Pre-FTL civilizations have a 3% chance to spawn in each habitable system, modified by the Pre-FTL Civilizations and Pre-Sapient Species game setting.
Pre-sapient species are species with intelligence beyond animals but which did not achieve sapience yet. It will take millions of years for them to become sapient, but spacefaring empires can accelerate this process, turning the pre-sapients into productive galactic citizens within the span of just a few decades. Pre-sapient have a 5% chance to spawn on each habitable planet, modified by the Pre-FTL Civilizations and Pre-Sapient Species game setting.
Pre-FTL civilizations[edit | edit source]
Please help with verifying or updating this section. It was last verified for version 3.7.
Pre-FTL civilizations exist in various ages of development they slowly go through, visible after an observation post has been constructed. They usually have the Developing Nation origin, but also have a 5% chance to have a regular origin as long as the required DLC is installed
Pre-FTL civilizations can always be invaded and conquered as long as their system has been claimed and the Pre-FTL Interference policy is set to Aggressive Interference. Pre-FTL civilizations have no means to resist a technologically superior invader, although Post-Atomic civilizations can be harder to conquer early game. Conquered worlds will get the Stellar Culture Shock modifier for 10 years, which locks out the former primitive pops from using colony ships, being resettled, joining Factions or being released as a Vassal. It also brings −20% Stability, −33% Resources from Jobs, and −50% Empire Sprawl from Pops.
|Available only with the Apocalypse DLC enabled.|
A Nanobot Diffuser can be used on a primitive world instead of conquest but will generate a temporary −40 Opinion from every other empire.
Awareness[edit | edit source]
Awareness is a measure of how aware a pre-FTL civilization is that alien life exists and goes from 0 to 100. It determines how many years Stellar Culture Shock lasts if an empire reveals its presence and, if First Contact DLC is installed, whether an Observation Post constructed above the pre-FTL civilization will produce Observation Insights.
Awareness has a chance to decrease each year by 1 as long as it is above 10. It also has a chance to increase whenever unnatural things happen in the same star system. The chance for Awareness to increase or decrease depends on the civilization's age.
- +1 each time an uncloaked ship enters the system or decloaks (6 months cooldown)
- +1 each time a starbase or station is constructed
- +2 each time an uncloaked science ship surveys the planet
- +2 each time an uncloaked fleet uses emergency retreat
- +5 each time an asteroid or ship is destroyed or disengaged
- +5 each time a planet is colonized
- +5 each time a megastructure is built or upgraded
- +20 each time a planet is terraformed
- +20 each time a planet is destroyed
- +20 each time a neighbor system is destroyed
- +2 each year as long as an uncloaked Observation Post is present
- +2 each year as long as a planet is colonized
Awareness can also be manually increased or decreased via espionage.
Age advancement[edit | edit source]
Pre-FTL civilizations will advance through ages as their history is written. Having an Observation Post built will notify its empire of every age advancement and let it check progress towards the next age by hovering over the age in the diplomacy screen. Depending on the current age and Awareness, it takes the following amount of years to progress to the next age:
|Stone Age - Late Medieval Age||160||120||80||70||60|
|Renaissance Age - Machine Age||80||70||60||50||40|
|Atomic Age - FTL Discovery||40||36||32||29||26|
Early Space Age civilizations that don't have an Observation Post built in orbit will eventually develop basic hyperdrives, turning them into a normal empire. If a Starbase was built around the star the new empire will ask the owner for control of it. Should the request be accepted they will be granted control of the Starbase and all colonized planets in the system and gain a temporary +100 Opinion towards the former owner. If the request is refused the civilization will be annexed. Annexing the civilization will cost 200 Influence if Xenophile or Fanatic Xenophile while granting it control of the system will cost 200 Influence if Xenophobe or Fanatic Xenophobe. Genocidal empires only have the option to annex the civilization.
There is no catch-up mechanism for these empires. Unless they advance very early in the game, they will likely be quickly conquered or turned into a Protectorate.
Nuclear war[edit | edit source]
Every 50 years there is a chance for any pre-FTL civilization that reached at least Atomic Age to start a nuclear war. The chances are the following:
- 49.6% chance nothing happens. This outcome is twice more common if the pre-FTL civilization is Pacifist or Fanatic Pacifist.
- 49.6% chance planet becomes a Tomb World with the Metal Boneyards planetary feature and the pre-FTL civilization reverts to Stone Age. Only 2 Pops will survive.
- 0.4% chance the planet becomes a Toxic World with a deposit of 3 Society and the pre-FTL civilization is destroyed. This outcome is twice more likely if the pre-FTL civilization is Militarist or Fanatic Militarist. If the Toxoids DLC is installed the planet will gain the Toxic Terraforming Candidate modifier.
- 0.4% chance the planet becomes a Tomb World with the Metal Boneyards planetary feature and the pre-FTL civilization is destroyed. This outcome is twice more likely if the pre-FTL civilization is Militarist or Fanatic Militarist.
The pre-FTL civilizations in the Sanctuary and Federation's End systems cannot start a nuclear war.
Asteroids[edit | edit source]
Very rarely an asteroid might be on a collision course with a planet inhabited by a pre-FTL civilization. Destroying the asteroid will grant 150-2000 Minerals and add 5 Awareness to the pre-FTL civilization. If the Non-interference Act resolution has been passed the empire will be in breach of galactic law for 10 years. If the asteroid isn't destroyed before it hits the planet one of the following will happen:
- 74% chance the pre-FTL civilization reverts to Stone Age and only 2 Pops survive.
- 24% chance the Observation Post is destroyed and the pre-FTL civilization gains 5 Awareness. If the Non-interference Act resolution has been passed the empire will be in breach of galactic law for 10 years.
- 2% chance the pre-FTL civilization gains 10 Awareness and progresses through the ages faster. This can only happen if the pre-FTL civilization reached Atomic Age or Early Space Age.
Observation posts[edit | edit source]
Observation Posts are stations that can be constructed above the homeworld of a pre-FTL civilization. Having an Observation Post enables diplomacy and espionage of the pre-FTL civilization and will notify the empire of any age advancements.
If the civilization is not aware of aliens the Observation Post will be able to conduct Passive or Aggressive observation and produce resources that scale with the Infiltration level on the pre-FTL civilization. Both types of observation can trigger various events. If First Contact DLC is installed and at least one Observation Post is built over the homeworld of a pre-FTL civilization that isn't aware of aliens the empire will gain the Observation Insights situation.
Any Observation Post will slowly increase the Awareness of the pre-FTL civilization. Observation Posts can cloak if the required technology has been researched, canceling this effect.
Diplomacy[edit | edit source]
Aside from improving and harming relations, regular diplomacy actions and agreements are not available with pre-FTL civilizations. However there is a small number of agreements available only towards pre-FTL civilizations:
- Reveal Our Presence is the only option if the pre-FTL civilization hasn't been made aware of alien life. It will make the civilization aware and enable diplomacy but will also cause Stellar Culture Shock for a number of years.
- Offer Societal Guidance costs 0.1 Influence and 5 Unity each month and will slowly shift the pre-FTL civilization's ethics to match the empire's.
- Provide Technology costs 0.1 Influence and 5 Research each month and causes the pre-FTL civilization to advance through the ages 3 times faster, or 4.5 times faster if the Equal Standing Act resolution has been passed. This option is only available if the Pre-FTL Enlightenment policy is set to Allowed. If the agreement is active when the pre-FTL civilization discovers FTL it will become a subject of the empire owning the Observation Post and gain a temporary +100 Opinion with it.
- Form Commercial Agreement costs 0.1 Influence and 5 Minerals each month and produces 0.5-4.5 Trade Value depending on the pre-FTL civilization's age. If the Equal Standing Act resolution has been passed and the planet contains planetary features that produce advanced resources those will be obtained as well. The agreement also enables empires with Corporate authority to open branch offices on the pre-FTL civilization's planet if the the civilization reached Atomic Age or Early Space Age. This option is only available if the First Contact DLC is installed.
Pre-sapient species[edit | edit source]
Please help with verifying or updating this section. It was last verified for version 3.7.
As opposed to primitives, planets of pre-sapient species can be colonized. The pre-sapient pops do not require either Housing or Amenities. The Pre-Sapients policy determines their status, and if set to Protected enables the construction of Alien Zoo buildings on worlds that contain pre-sapient pops. Unlike sapient species, pre-sapients can be purged without diplomatic repercussions.
Terraforming a planet will cause the death of any pre-sapient pops on the planet.
Sapient pops can be turned pre-sapient with the Devolving Beam colossus weapon.
Uplifting[edit | edit source]
For pre-sapient species the option to create templates is replaced with the option to Uplift them. The planet must be colonized and within the player empire's borders. Uplifting a species requires the Epigenetic Triggers technology and costs 3000 Society Research. Uplifted species become part of the empire that uplifted them and get a +10% happiness bonus when inhabiting that empire's planets due to getting the Uplifted trait. Finishing an uplift also grants 50 influence.
When an uplift is complete, the pre-sapient species receive the default species rights according to the host empire, even if it is displacement from their own home. Most uplift processes tend to be rocky (70% chance of -5% planet mineral output).
Unlike pre-FTL civilizations, pre-sapients will never advance to sapients on their own in-game.
