As Factions expand into the solar system and trade among themselves, they become less dependent on Earth and less tolerant of Earth-centered trade limits and regulations. Secessionists start to clamor for independence and self-governance. But if war is declared, the game state changes drastically until it is resolved, with hot fighting between the Loyalists and the Independents. At stake: will space ventures be subject to Earth regulations and governance by terrestrial superpowers and multinational organizations like the UN, or will they be a bunch of self-governing city-states?

This is an expansion require that you have the core game High Frontier 4 All.
