3.6 - 2.7 Billion Years Ago

Vaalbara was a supercontinent, possibly the first in the history of the Earth. It arose in a world dominated by oceans and small volcanic Island chains, a punishing world of low oxygen, crushing pressure, and intense heat. 

But even in this hostile early world, life was beginning. Stromatolites, layered mounds of rock deposited by cyanobacteria, lined many of Earth's rocky coasts and were just beginning to create the oxygen-rich atmosphere we know today.

About[edit | edit source]

Completing Vaalbara will unlock Rodinia.

The factions Daughters of Gaia and Sons of Hephaestus both invite the player to terraform an in-game simulation of what Earth was like back then in their own way. They tell the player that the simulation will teach an A.I. how to automatically terraform other planets. The player gets to decide which advice to follow.

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 / 1.000.000.000c revenue for Horizon Corporation).

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.

Strategy[edit | edit source]

For terraforming

Be sure to decrease the amount of water in the atmosphere before you decide to cool down the planet, otherwise your planet will flood. Decreasing pressure will also decrease your temperature, so don't do that yet either. Don't hang around in the game too much, because there is a special event in which the Daughters of Gaia will drop in randomly to 'help' by moving temperature, pressure, oxygen or water levels closer to the ideal, which has the potential to instantly flood your planet.

Keep in mind that there is a lot of vapor in the atmosphere. You will need Spaceports and Ice Launchers, both of the same level, to reduce the water level. It will not be huge, but it is a good start.

Although it may seem easy at first sight (it has a visible ocean), it is incredibly difficult to maintain the water levels.


For conservation

Like in the terraforming scenario, you will need to keep an eye on the water level. Most of the planet’s water is in vapour form, and as long as you don’t dramatically lower the temperature (directly or by lowering pressure) it should stay that way. However it is still possible to accidentally flood the planet when correcting for pressure, so be careful.

The soletta is entirely useless for conservation on Vaalbara, since the starting temperature is outside the soletta’s maximum temperature. Heat should be regulated instead through pressure.

The acceptable range for oxygen levels on Vaalbara is extremely narrow, with a starting level of 800 and 40 either way. It is best, if possible, to avoid building anything that affects oxygen levels at all - for example, you might want to skip hab complexes on the way to hab domes. Of course, you will need to correct for Alana’s interventions (which will most usually target oxygen).

Biosphere[edit | edit source]

Vaalbara only has one native species when you first start a new world. Click the links for more info on biospheres and phyla and traits.

Trivia[edit | edit source]

The first life-forms evolved around this time period.

Even though Vaalbara was shown with a clear atmosphere in the Historical Earths pack, Vaalbara has a atmosphere that completely covers the planet. If you play with biospheres the only species is stromatolites, which are colonies of cianobacteria. The stromatolites can easily go extinct in-game. In real life stromatolites still live on Earth. Some of them are nearby the coast of Australia.

Vaalbara was the first hypothetical supercontinent in Earth's history. It began forming 3,6 billion years ago, finished forming 3,1 billion years ago, and ended it's existence 2,7 billion years ago, which makes it the earliest Earth's supercontinent.

Dialogue[edit | edit source]

After you pick a faction (only UNSA and Horizon are available), a dialogue starts playing. At the end of the dialogue you can start playing Vaalbara. The dialogue has no impact on the missions you're given.
