About the Game
Lead humanity from its infantile cradle to supreme solar dominance in Solar Nations 2, the grand strategy game where the Solar System becomes an intricate battlefield.
Build colonies on distant worlds, develop revolutionary technologies, and decide whether humanity will unite among the stars… or destroy itself in nuclear fire.
LEAD HUMANITY INTO SPACE
The nine planets of Sol are waiting to be conquered. Each one offers unique advantages, dangers, and strategic possibilities:
Mercury offers the closest access to the Sun.
Venus presents a high-risk, high-reward terraforming gambit.
Earth is rich in population and industry, but divided by old rivalries.
Mars boasts valuable resources and proximity to the Asteroid Belt.
Jupiter’s moons each provide unique opportunities for colonization and conflict.
Saturn holds a wealth of rare resources waiting to be discovered.
The Ice Giants present strange research opportunities at the edge of civilization.
The Kuiper Belt is a gateway to the unknown.
And beyond Neptune, the ninth world waits.
DETAIL WITHOUT TEDIUM
Solar Nations 2 allows great breadth and depth at once.
In war, you command vast space fleets to conquer the planets, while also intricately customizing each vessel to fit a role of your choosing.
In peace, you carefully navigate the political intrigues of an interplanetary society, while constructing great projects which will stand as testimonies of your greatness to future generations.
WAR OF THE FUTURE, FOR THE FUTURE
The civilizations of mankind are not divided by borders alone. They are divided by worldviews, ambitions, myths, fears, and rival visions of what humanity should become.
Every nation believes it has a unique claim on the future. Every ideology carries its own sense of righteousness. As mankind spreads beyond Earth, these old struggles do not disappear, instead they expand across the void itself: becoming greater in some ways and in others remaining the same.
Combine armies, aircraft, ships, spacecraft, and strategic weapons into an unstoppable war machine, with each force playing a distinct role in the great game of civilizations.
UNLIMITED POWER
In Solar Nations 2, you are the master of your nation's destiny. Everything which happens within your borders is something you preside over - there is no need to rely on AI help. Each mechanic is simple enough to understand while also offering strategic depth to ensure there is a wide variation of choices, where there isn't always a best solution.

AI behavior changes
Hello everyone, I was made aware of an issue where the credits were not displaying properly. This is something I had overlooked, and it led to concerns about some of the exoplanet textures (which are from SpaceEngine, if you did not know). SpaceEngine PRO allows for commercial use of their textures (which are very good), and I have SpaceEngine PRO on my main steam account. However, since the credits were not displaying correctly, people did not know this, so I have added a credits.txt to the game files so that everyone knows what kind of external media I used when making the game.
Sorry for the misunderstanding, the lack of clarity was my fault.
Hello everyone. Today I have some more changes for the experimental branch. I have been working on localization recently, but have so far been unable to make good translations since I do not know any language other than english, however the backend support is now there.
Changelog
Back end multiple language support (no idea how to translate properly yet)
AI behavior changes
Evil Crisis situations are now very different: they are "good" and give you bonuses but you can easily lose control of them and become Moloch/Eugenarchy.
Standardization of mod .json file naming convention. If yours "wasnt working" it was because of a load-order problem that only showed up on about half of machines.
Notification Settings: customize which notifications create popups
Bug fixes

Made automatic unit control update more frequently
Fixed overflow damage bug with losses penalties
