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.

Experimental Icon Changes
I thought the white glowy borders on the icons looked bad on smaller resolutions, so I decided to change them by inverting the colors and hue shifting. This has been done to every icon which had a white border, and I am dubious as to whether or not I would like to make these changes permanent. Overall, I think it is good though.
