There are four types of resources that can be used in your corporation’s work to terraform Mars: MC, plants, heat, and special resources (animals, microbes, and science).
This is the currency used in the 24th century and is how your corporation will pay to complete projects and take certain actions.
Plants represent the hard work your corporation is putting in to increase the forest coverage on Mars. Plants are a resource you can use to build forests and raise the oxygen.
Heat represents your corporation's efforts to make the temperature of Mars habitable. Heat is a resource you can use to raise the temperature 2˚C.
Your corporation can invest itself in the animals, the microbes, or the science resources of humanity's future home. These three special resources are collected on project cards to be used for specific effects.
