Synthetics are an easter egg state that is created using the console command syntheticdawn. They will substitute themselves to a country, which can be chosen by adding the country tag after the command's name. (Ex. syntheticdawn FRA will make Synthetics annex Flag of France France).


Synthetics have Easter events dedicated to them, notably one where Flag of Maya Maya can open a temporal rift to fight them, and also a unique set of ideas.


Msg event.pngSynthetic Dawn

They came from the sky in immense metal vessels larger than a city. The slaughter began as soon as they disembarked; unfeeling monsters covered entirely in armor and with no discernible flesh or blood exterminated all in their path. The Synthetic invasion has begun.

Prepare for the worst.

Msg event.pngSynthetic Dusk

The last of the Synthetics has been destroyed. Though much of the world now lies in ruin and countless people have lost their lives, the world is finally rid of them. Scavengers mill over their static husks searching for some clue as to how these murderous automatons were able to function and what drove them to invade our world. They find few answers. But perhaps some of the technology they left behind might be adapted to our own purposes.

The Synthetic invasion was foretold in the prophecies.

Another Paradox Interactive videogame, called Stellaris, features space colonization. In this context, an alien country ruled by robots (the Synthetics) found a primitive world, Earth, and decided to invade it. This easter egg has been preannounced by tweets on the Twitter pages of Europa Universalis IV and of Stellaris, through encrypted messages.
