Terraforming is the act of changing the planet classification of a celestial body in order to make it more habitable for the empire's citizens. Terraforming also removes all tile blockers from the surface. This requires significant Society Research.png society research, Energy Credits.png energy credits, and time.

Terraforming requirements[edit]

Terraforming is started via a button on the World Detail view. The world must be surveyed and within your borders. Only habitable-type worlds, Tomb Worlds, and special Barren Worlds that have the rare "Terraforming Candidate" modifier can be terraformed. Since these rare candidates cannot be searched directly, it is important to note them down manually or via rally points when the player comes across one or encounters the anomaly that uncovers the modifier. Until a suitable terraforming management screen is implemented in some future patch, it is simpler for players to make a copy of the save file, renaming the copy to .zip, uncompress it, and then search the game state file for planets with the "terraforming_candidate" entry.

The requirements for terraforming a world depend on the magnitude of the change. A change within the same climate (wet, cold, dry) is faster and cheaper than a change between climates. Barren worlds are considered to be closer to Dry or Cold Climate, depending on the subtype.

It is possible to terraform inhabited planets if you have the technology Tech ecological adaptation.png Ecological Adaptation. Doing so gives a -20% happiness penalty to the planet.

Cost reduction[edit]

The World Shaper Ascension Perk doubles the terraforming Speed. Terraform Gases.png Terraforming gases and Terraform Liquids.png Terraforming liquids both reduce the energy credit cost of terraforming by -25% each, stacking for a -50% cost reduction. Ruler trait World shaper World Shaper decreases terraforming cost by a further -15%. Finishing the Prosperity Tradition cuts the cost by another -33%, for a total possible cost reduction of up to 98%.

Alternatives to terraforming[edit]

Terraforming is only one way to allow a species to better live on a planet. For the others see: Colonization#Colonization_through_diversity and Celestial_body#Habitability_Strategy
