About the game
Plan B: Terraform is a strategy-simulation game by Gaddy Games in which players transform a barren, lifeless planet into a thriving, habitable world. Across a vast hexagonal surface, players construct factories, railways, and truck networks to grow a population into the millions. A dynamic simulation of atmosphere, temperature, water cycles, and forests underpins the entire terraforming process.
Did you know?
Plan B: Terraform was both developed and published by the same studio — Gaddy Games — without the backing of a larger publisher.

Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
