Terraforming is the process of altering the surface conditions of Mars to make the planet hospitable for humans and ultimately turn the planet Earth-like. It is the largest investment of resources on Mars and can be disabled by the No Terraforming Game Rule.


Terraforming ParametersEdit

Terraforming Parameters are 4 surface conditions that determine the overall terraforming progress. Once a parameter reaches 100% it is identical to Earth's.

Parameter Improvement effects Description
  • Decreased severity of Dust Storms and Meteor Storms
  • Increased production from Wind Turbines and MOXIEs (+100% max)
  • Decreased production from Solar Panels (-50% Max)
Represents the density and composition of the Martian atmosphere. The higher this parameter is, the more Earth-like are the atmospheric pressure, Oxygen levels and cloud generation.
  • Decreased severity of Cold Waves
  • Permafrost starts melting above 50%
Represents the global surface temperature of Mars. The higher this parameter is, the more favorable are the conditions for Earth-like life.
  • Increased production from Moisture Vaporators (+100% max)
Represents the quality and volume of surface water on Mars. The higher this parameter is, more and larger water bodies will appear on Mars: lakes, seas and oceans.
  • Increased plants spread
Represents the spreading and diversity of vegetation and bacterial life on a planetary scale. The higher this parameter is, the more Mars looks like the tundra biome back on Earth, with the ultimate goal to become a quite harsh, yet habitable second home for humanity.

Terraforming ThresholdsEdit

Terraforming Thresholds are values of Terraforming Parameters above which drastic changes will occur on Mars.

Terraforming BuildingsEdit

Terraforming buildings are the main way of terraforming Mars. They have very high construction costs and should only be built by a self-sufficient colony.
