Our world has expanded before us. Corporations spread out their operations to all corners of the solar system in search of minerals and resources. Most places are not set up for terraforming, but developing colonies may greatly improve your income and your possibilities in achieving that higher goal — the terraforming of Mars. Dispatch your trade fleet to distant moons! Colonize clouds of Jupiter! And allow your Earth assets propel you to success! Terraforming Mars: Colonies, an expansion for Terraforming Mars that can be played with only the base game or with any combination of expansions, lets you visit the outer solar system. It features colony tiles where you can build colonies and send your trade fleet. It also includes new cards and corporations.
