Gaddy Games’ peaceful planetary sim Plan B: Terraform is finally reaching full release. After a well-supported Early Access run packed with new features and gameplay refinements, version 1.0 officially launches on Steam August 29, 2025, just in time to cap off Steam’s Automation Fest.
If you haven’t tried it yet, Plan B: Terraform lets you do exactly what it says on the tin: turn a barren, lifeless world into a living, breathing ecosystem. It’s part supply chain sim, part climate science sandbox, and 100% chill.
Terraforming at Scale
Unlike your usual factory builder or city sim, Plan B: Terraform plays out across an entire planet made up of over a million hexes. Starting with basic resource extraction, you’ll eventually manage a vast logistical network of trucks, drones, trains, and container ships—all working together to grow settlements into cities that can support millions of inhabitants.
But infrastructure is only half the equation. You’ll also raise global temperatures using greenhouse gas generators, melt underground ice to form oceans, and slowly develop a balanced climate system that supports vegetation and animal life. And yes, it’s all grounded in real-world environmental modeling.
What’s New in 1.0?
The 1.0 launch adds even more tools for shaping your planetary utopia:
-
Creative Mode: Total control over terrain, temperature, and population to freely build your dream planet
-
Dynamic Wildlife: As you restore ecosystems, creatures like deer, bears, and eagles return to the land
-
Flight View: Take to the skies and admire your terraformed world from a brand-new perspective
-
New Music Tracks: A fresh soundscape to complement the meditative gameplay
These come on top of previous updates that added container ships, overhauled objectives, improved UI/UX, terrain refinements, and essential building tools like multi-selection and undo.

-
Planetary-Scale Terraforming: Simulate climate shifts, rainfall, rivers, forests, and more in real time
