Mars Modules Edit
The Hab Module is a more comfortable place for Mars workers. Each of them hold 20 people.
Combine 4 of the 1x1 Mars Habitat Modules to make this Hab Module. These Hab Modules need 3000 W of power, so keep building those Deuterium Reactors.
Build the Life Support Module first as this can be placed anywhere, and all other 2x2 modules must attach to a 2x2 already in place.
See the Mars Inc.list for more Mars buildings.
