Our new home. After eight generations in this hollowed-out asteroid, we have finally arrived at TRAPPIST-1.

Begin by disembarking on Huanca. Our advance scans indicate that it is the most suitable to human life, and will make an excellent base from which to expand out into the rest of the system. From there, you can begin to explore TRAPPIST-1 and discover what mysteries lie within.


Huanca or TRAPPIST-1d is the first planet you need to complete before you can play the rest of the TRAPPIST-1 story campaign. Completing Huanca will unlock Damu, Aja, Ruaumoko, Asintmah and Aranyani, but not Ostara (this needs to be unlocked by colonizing all other TRAPPIST-1 planets).

Huanca does not have natural satellites.

Text before colonizing other TRAPPIST worlds:

We hope to eventually settle all worlds in this system, but first we need to establish a solid foothold.

Our generation ship contains supplies for hominizing Huanca, and only after we have successfully that world can we attempt to tame the more hostile planets near it.

Complete Huanca before attempting to land on this world.


You just need 20 CP (culture points) to win on a TRAPPIST-1 world so put down a city, put an extra habitation and wait in the game for 20 CP from random events or you can use the strategy below.

When you increase the pressure levels, the sea levels will also increase, so you need to research GeoCistern and/or Ice Launcher and also a Spaceport build facilities in your cities.

You can also build cities on the dark side (and also watery) part of Huanca, because there are some islands on it.


  • Huanca(TRAPPIST-1d) is in the conservative habitable zone of its star. It is the closest to the host star out of all the habitable zone planets with an equilibrium temperature just a bit hotter than Earth’s.
  • This planet is thought to be one side too hot, the other one full of ice due to it's tidally locked to TRAPPIST-1. And in the twilight zone, there may be some liquid water on the surface. If it had an ocean and thick enough atmosphere, heat would be distributed more evenly.
  • The dark side might harbor some liquid water instead of ices.

Victory - Spoiler Alert[]

Instead of spending culture points on independence, you spend them on investigation and decryption. Victory is achieved when you spend 20 culture points on this, regardless of whether you've achieved your faction's normal goals.

"Upon landing on Huanca, our scientists began picking up strange signals coming from beneath the surface. The signals are weak and intermittent, but each time they cycle we become more convinced of the impossible: that we are detecting an ancient alien device, long left abandoned by its creators. If we can find this device, who knows what we could learn from it?"

- investigation: Each step brings you closer to the device.

"Your scientists have found the device, but cannot understand it. It seems willing to interface with our systems, but it is simply too alien to be intelligible. Our best linguists are working on it, though, and we hope to have an answer soon."

- Decryption: At 100%, victory is achieved.

After completing Huanca, you will be allowed to use the Tresuunak on subsequent TRAPPIST-1 worlds, allowing you to access the Satellites tab early.

Victory Text[]


For centuries we have wondered if we were alone in the universe, the only species capable of exploring the stars. Well, now we have our answer. After generations of work in the most momentous hominization effort in the history of humanity, Huanca is now home to [number] people. It is a hub of culture, learning, and innovation, a shining jewel in humanity's burgeoning interstellar community.

And most breathtaking of all: the ship. After centuries of study, our scientists have finally learned enough about the alien structure to deduce its true purpose. It is a ship, massive in scale, designed for interplanetary and interstellar transport. Preliminary translations seem to refer to it as the Tresuunak, a name derived from the mythology of the long-forgotten alien race. The tale speaks of a great adventurer who built a ship to explore the heavens, but before she could conquer them she would need to recruit help from 'the sea, the sky, the past, and the future.' Our scientists don't know what this refers to, if anything, but studies are ongoing.

In the meantime, the Tresuunak is ready for launch. It could prove to be a huge help in our continuing exploration of the TRAPPIST-1 system, for not only will we be facing the usual dangers of hominization and terraforming, but there will no doubt be other alien devices on these worlds as well. Even more intriguing, the Tresuunak seems to have several empty slots where other components could be installed. Who knows what the ship will be capable of, when fully upgraded?
