Evaluation

Solar Nations 2 entered Early Access on January 31, 2025 and has been receiving frequent, substantial updates from its solo developer at Flomgus Games. The game continues to add major new gameplay systems with each update cycle: Update 0.17 (May 14, 2026) introduced espionage and favors diplomacy; Update 0.18 (August 5, 2026) added mission trees, a new crisis faction (The Imaginarium), a ledger system, and expanded asteroid belt content; and Update 0.19 (September 24, 2026) introduced generation ships and a video rendering tool. A follow-up patch (0.19b Update 3) shipped on September 27, 2026 — just four days before today — adding new wonder graphics and gameplay settings. On July 29, 2026, the developer explicitly announced that the planned 1.0 full release has been delayed from August 2026 to January 2027, citing a desire for more polish, bug fixing, balance improvements, and additional content before leaving Early Access. The developer noted the delay was supported by a community Discord poll and stated that Early Access will continue as normal in the interim. The development pace remains active and consistent, with major updates shipping roughly every 2–3 months and smaller patches in between. The game is clearly not finished — the developer has set a January 2027 target for the 1.0 release and is continuing to build out systems and content.

About this 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.
