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 Parameters[edit]

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
Atmosphere.png Atmosphere
  • 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.
Temperature.png Temperature
  • 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.
Hydrosphere.png Water
  • 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.
Vegetation.png Vegetation
  • 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 Thresholds[edit]

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

Terraforming Buildings[edit]

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.
