Planets in sight, get ready to expand our Colonies

Terraforming Mars: new DLC Colonies is coming on January 22nd

Terraforming Mars' latest DLC is coming on January 22nd at 7PM CET, save the date and have a look at its very brand new content.

Or take the leap and discover an updated Collection Bundle including the base game and all the precedent DLCs:

  • Adding a new Colony system, this DLC will push you to expand your horizons, develop a trade fleet and find a way to reap the benefits before anyone else. 

  • It includes 49 new project cards that interact with other DLCs while still standing on their own. Purchase your fleet, develop Warp Drives or dabble in Molecular Printing - the choice is yours. 

  • 5 powerful Corporations, including the colony-heavy Poseidon or the animal and plant-loving Arklight. 

  • 11 Colony tiles, each with their unique bonuses. Since they scale with the number of players, not all colonies will be available in every game — forcing you to adapt and seize the best opportunities.
