You can spend hours planning and building your base in the chill, sandbox-style Builder mode.

Check a short gameplay here:

choose between Survivor or Battler modes with environmental disasters such as heat bursts and fire, where you need to focus more on taking care of your mutant crew’s needs.

It is a source of moisture for vegetation, power for your factories, and even a weapon against aggressive Martian flora.

• Not enough space for factories? Shape the terrain, first manually, then automatically with a soil cannon.
  
• Not enough moisture for your fields? Bring water through pipes and spread it with sprinklers.
  
• Heat burst causing water sources to dry up? Store water in liquid tanks.
  
• Not enough wind for your windmills? Build an atomic plant to produce enough power for the whole base.

The best part is that the many excellent features are still coming!

As you can see, the game is in Early Access but is continuously updated, with the full release planned for fall of this year, when the price will increase slightly.
