Resources

Resources are very important in Mars Tomorrow. Every outpost in the game produces one or two types of Resources. For example, the Air production outpost produces Breathable air.

Most Outposts in the game also require Resources to produce Resources. Let's keep using the Air production outpost as an example. Air production produces Breathable air, but it requires Oxygen to do so. The more Resources an outpost has, the faster that outpost will produce Resources.

You also unlock several types of new Resources (and Outposts) every time you proceed to the next phase.
