Humanity has begun to spread throughout the solar system. On Mars, a few small colonies have been built. These offer protection from the environment, from a planet which is terribly cold, dry, and with almost no atmosphere.
 
To be able to increase immigration from Earth, Mars needs to be terraformed by altering its environment until humans can live there without expensive protective gear, and without even minor accidents becoming lethal. Therefore the World Government has decided to support any organization that contributes to this vast undertaking.
 
The generous funding attracts gigantic corporations that compete to expand their businesses and emerge as the most influential force behind the terraforming. In this era, great opportunities lie in the taming of the Red Planet.
