Welcome to Mars! Feel free to make yourself comfortable. In Terraforming Mars, you are a corporation trying to make the red planet habitable for human settlement. Over the course of generations, your corporation will fund and carry out projects designed to increase the temperature and oxygen level in the atmosphere to transform a barren world into a lush and habitable planet. Beware, though, as other corporations are vying for the chance to be the most successful terraformers out there. Buckle up and plan ahead! You'll need foresight, planning, and just a little bit of luck to come out on top!
