Galactum Meridian

Galactum Meridian is a research-focused space strategy game about leading humanity’s first deep survey beyond Sol. You command the ISA Far Horizon, a deep-survey cruiser sent to investigate nearby star systems where maps are incomplete and data is uncertain. Rather than expand through fleets and conquest, you build a picture of humanity’s interstellar future through exploration and scientific discovery.

Explore nearby stars

The galaxy is built on real astronomical structure, including nearby stars, confirmed exoplanet data where available, and information from sources such as the NASA Exoplanet Archive. The game includes more than 10,000 stars from current catalogs, which are updated frequently as new data becomes available. Known science provides a foundation for survey results, modeled possibilities, fictional worlds and other discoveries; some findings are observed, some inferred, and others remain mysterious.

You navigate a 3D star map and survey stars, planets, moons and other objects. You inspect worlds from orbit and investigate them through surface studies, anomalies, fossils, terrain signals and environmental hazards.

Lead the expedition

The Far Horizon serves as a mobile observatory, laboratory, probe carrier, mission hub and lifeline. You deploy probes, orbiters, landers, rovers and specialized field-study packages, then follow up on unusual readings. Discoveries inform research, mission priorities and strategic authority.

Aboard the ship, you can also follow mission briefings, crew records, Accord transmissions and discovery archives.

Research and stewardship

The 3D branching Research Atlas is the game’s progression system. You spend insight earned from discoveries to improve probes, extend survey reach, strengthen the Far Horizon’s support systems and open strategic options. Geology, biology, climate science, stellar physics and comparative planetology all contribute to the expedition’s growing capabilities.

The game adapts the 4X formula around science, survey rights, publication and stewardship. You explore unknown systems, expand your research footprint and turn discoveries into useful capabilities. Its 3D strategic stewardship layer represents your expedition’s reach, credibility and recognized scientific authority, rather than ownership of a flat region of space.

Rival expeditions

The ISA has sent other expeditions into the frontier. Their crews compete to publish first, secure Stewardship Authority and influence the official record of humanity’s discoveries beyond Sol. Some readings do not fit existing models, and some worlds contain evidence that should not be there. The Far Horizon may uncover something that changes what humanity believes about life, intelligence and its place in the galaxy.
