ABOUT THE GAME

Operations on the ground surface are
Spreads throughout the planet.

"Gaia Maker" is a simulation where you play as a planetary supervisor and use advanced technology to transform a desolate celestial body into a living world. We handle temperature, biomass, carbon cycles, solar radiation, and atmospheric composition on a planetary scale, and connect operations on topography and facilities to changes throughout the world.

01

Calculate the entire planet based on physics and geology

The official explanation states that it is a simulation of the entire planet, including temperature, biomass, carbon cycle, solar radiation, and atmospheric composition. In the same world, we not only deal with operations on a single point on the earth's surface, but also how the results chain to the atmosphere and ecosystem.

02

Recombining environmental conditions with facilities and technology

Obtain resources from fusion reactors and Dyson swarms, and use facilities and methods such as oxygen generators and aerosol injection. Move back and forth between building lists and environment layers to break down planet-scale objectives into individual equipment.

03

From animals to civilizations are subject to change.

Once the environment is set up, the simulation includes the breeding of animals, expansion of their habitat, evolution of civilization, and impact on the planet. Dynamic events that affect civilization, such as epidemics and wars, are also listed as major official functions.

RESHAPE A WORLD?

From a barren planet,
Towards the formation of the biosphere.
