Terraforming Mars - Colonies

About this game

Mars is no longer enough — spread humanity amongst the stars with the Colonies DLC

Establish outposts, make them grow, and use your trade fleet to reap the rewards — or lose it all to a faster opponent!
In this DLC, you will find:

  • A new Colony system, alongside the merchant fleet. Establish colonies and trade with them to outpace other players
  • 49 Project cards, allowing you to purchase trade fleets or expand your usual strategies even further
  • 5 Corporation cards, including the colony-heavy Poseidon or the nature-loving Arklight
  • 11 Colonies, each with its unique bonuses

Ready to bring capitalism and progress to the entire solar system?
