Surviving Mars Green Planet

Surviving Mars: Green Planet is an add-on about terraforming Mars and making it habitable as a second home for humanity. Your colony’s decisions affect the planet’s Atmosphere, Temperature, Water and Vegetation. Track these Terraforming Parameters across the planet with the Planetary Overview UI.

Grow a greener Mars

Seed the surface with lichen, grass, shrubs and trees, and monitor soil quality to keep plants healthy. Low-maintenance lichen can improve soil for more complex plants to grow, while trees produce high seed yields for your colony to harvest.

Terraforming projects

Seven Special Projects can shift the Terraforming Parameters, including melting the polar caps, capturing ice asteroids and launching a space mirror. These projects have lasting effects on the planet and can trigger natural disasters.

You can also construct seven new buildings to change the planet or make use of its transformation. The GHG factory releases greenhouse gases into the atmosphere, the Forestation Plant boosts vegetation production, and the Water Pump fills lake beds.

Climate calamities

Terraforming can have unexpected consequences. Releasing too many greenhouse gases can trigger acid rain, which reduces soil quality. An asteroid strike can cause a Marsquake that disrupts your colony’s production.
