What the developers have to say:

Why Early Access?

“I think the game is ready to provide a fun and original experience to you. And your feedback will help me to add content and improve the game as best as possible.”

Approximately how long will this game be in Early Access?

“My objective is to keep the game in Early Access during one year, up to early 2024. But the planned features will probably evolve depending on your feedback, and so could the release date.”

How is the full version planned to differ from the Early Access version?

“I hope to be able to add more items (like terraforming mechanisms), to craft the storytelling, etc. Like I did with my previous game Dig or Die, it will mostly depend on your feedback.”

What is the current state of the Early Access version?

“You can play up to end: get 1 million people, and a terraformed planet with forests. Only there is no storytelling yet (but an intro), and a limited number of items.”

Will the game be priced differently during and after Early Access?

“I will increase the price with each major update. So you don't take risk on buying it now: you pay only for what is already done. And the future additions will be a bonus.”

How are you planning on involving the Community in your development process?

“I read everything on the Steam forums and the discord, and I enjoy disussing your feedback and future updates.”

About This Game

Manage the resources of a newly discovered planet. Bring supplies to the cities and manage its terraformation.

  • Extract minerals, transform and transport them to the cities, so that they can expand and progress.
  • Build terraforming devices, such as greenhouse gas factories, in order to progressively warm up the atmosphere, make the ice melt and make rain fall, until rivers and oceans form. Then, when the conditions are met, you will be able to plant trees and watch them grow into large forests.

Plan B: Terraform is a calm and contemplative science-fiction game based on a credible near future. It also offers an educational approach to greenhouse effects and water cycle mechanisms.

Earth has a very hard time limiting global warming and its catastrophic consequences. Humanity needs a plan B in order to ensure its survival. This is up to you!


  • Huge planetary scale playground, composed of more than a million hexagons.
  • The "real" terraformation of a planet, with a global and real-time simulation of temperature, vegetation, rain and water flowing to form dynamic rivers and oceans.
  • Radical evolution of the population, from a few inhabitants to a million and more.
