145 - 66 Million Years Ago

The Age of the Dinosaurs. Giant, terrible lizards roam a steamy, tropical Earth. Plants pile atop each other for a chance at a bit of warm sunlight, and marshes and swamps cover massive swaths of Earth's surface.

The entire planet is bursting with life, but see that bright light in the sky? Does that look like it's coming at us?


This world can only be played after you complete Cambria. Completing Cretacea will unlock Dania.

Victory is achieved when you reach 100% independence and have fulfilled either the mission the Daughters of Gaia gave you (paradise habitability) or the one Red gave you (kept stats within 5% of original stats). You don't need to complete the normal goal for the faction you chose (500.000.000 population for the UNSA / revenue for Horizon Corporation).

Regardless of what you did on the previous planets, you can still choose to fulfill Red's or Alana's mission.

You have been granted access to a secret project under development by a foreign power: an automated system currently being taught how to terraform a planet.

One side wants you to terraform to Paradise, the other wants you to maintain the starting stats of the planet. it's up to you who to side with. At the time you reach completion for each world, your choice will be finalized in the computer's memory.

When you start playing Cretacea, the world will already be producing 40 biomass/ minute because of natural growth. Biomass is now covered within Earth, that is, 900 Gt.


Cretacea is the only world on which you can get Worldkiller Asteroids on Normal mode, so be sure to install a Planetary Defense Network. The reason the developers made Cretacea the exception, is because during this era the non-avian dinosaurs were wiped out by an asteroid.


Map Cretacea.png

You can already see our modern day continents forming on Cretacea when comparing its map to our modern map.

Dinosaurs roamed the land and the first flowering plants and butterflies appeared in this time period.

There are some inaccuracies in the map than the previous one.

  1. India is connected to Africa but not Madagascar.
  2. South America and Antarctica are connected with a land bridge but it is a big no no.
  3. Some islands that are present today are existing in this map, like the Philippines.
  4. One of Indonesia's islands appear on the Pacific Ocean but not on Australia or New Guinea.
  5. Arabia is connected to Asia and it is supposed to be connected to Africa.
  6. The Himalayas and the Tibetian Plateau show up in the map but it is still not yet forming in real life.

The Earth as seen from Space[]

The Earth 100 million years ago. The red dot represents Sydney, Australia.

South America and Africa separate from each other. North America and Scandinavia are still connected to each other. The South Atlantic Ocean forms. The still connected Antarctica and Australia move again. The Pacific is now filled with tiny islands that we see today. New Zealand is on the south pole and drifts north. India and Madagascar separate and a piece of land below them disappears and became an island chain. After the separation of these two, India drifted north to Asia and Madagascar became locked to the African plate. North America rotates clockwise and Eurasia goes south. Much and much is happening in this time period and the last supercontinent Pangaea broke apart into the continents that we see today.
