Terraforming Mars, (digital board game) in which you change Mars into a habitable planet, is being given away for free by Epic Games.

Corporations are competing to transform Mars into a habitable planet by spending vast resources and using innovative technology to raise temperature, create a breathable atmosphere, and make oceans of water. As terraforming progresses, more and more people will immigrate from Earth to live on the Red Planet. In Terraforming Mars, you control a corporation with a certain profile. Play project cards, build up production, place your cities and green areas on the map, and race for milestones and awards.

Just head over to Epic Games Store or navigate to the game in the Epic launcher before May 12th 2022, add the game to your cart and checkout. Simple as that. After that, the game is yours to keep, and play, forever.
