Manage a newly discovered planet, contemplate your world evolve and grow your population. Mine resources, process and transport them to the cities to keep colonizing. Your mission is to terraform your planet to make it inhabitable: warm up the atmosphere, form rivers, oceans and grow forests.

Plan B: Terraform is a calm and contemplative science-fiction game based on a credible near future. It also offers an educational approach on greenhouse effect 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!

Gaddy Games announce that Plan B: Terraform will be leaving Steam Early Access and officially launch into v1.0 on August 29, 2025.

After a robust Early Access period marked by continuous evolution—including overhauled levels and objectives, new transportation systems like container ships, and key improvements to the UI and terrain—Plan B: Terraform is ready to deliver its complete vision of humanity’s future on a new world.

Version 1.0 introduces new ways to shape the world, bring it to life, and experience it from new perspectives. Creative tools offer full control over the environment, from terrain and temperature to city creation and population. Witness wildlife like deer, bears, and eagles appear as the ecosystem comes alive—and even take to the skies for a fresh perspective. Alongside these additions, new music tracks arrive with 1.0.

A free demo is available now as part of Steam Automation Fest.
