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 society research, Energy Credits.png energy credits, and time.

Terraforming requirements

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. The expansion planner screen can be used to find these rare candidates.

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.

Change Technology, Ascension Perk or Modifier required Cost Time

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

Cost reduction & Speed

  • Access to Terraform Gases.png Terraforming Gases or Terraform Liquids.png Terraforming Liquids strategic resources decrease terraforming cost by -25%, stacking for a cumulative -50% cost reduction.
  • The World Shaper Ascension Perk increases terraforming speed by 50% and decreases cost by -25%.
  • Ruler trait World shaper World Shaper increases terraforming speed by 25% and decreases cost by 15%.

Alternatives to terraforming

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
