Plan B Terraform v1.0.5.1252 (upd.31.12.2025)

Tribe Primitive Builder — is a calm and meditative sci-fi colony simulation game with terraforming elements. In the near future, it became completely clear that humanity needs a backup option in the face of another planet. You will play as a colonizer who was sent to a lifeless planet that has all the makings to turn from a desert into a real blooming oasis. Initially build a small colony and start extracting the most important resources. Adopt the first colonists to your colony and start multiplying their number by creating new colonies.

The more colonists, the faster you collect resources and the more you can build devices for terraforming. For example, try heating the atmosphere to melt the ice and cause precipitation. The game has a huge number of tools for terraforming, and the process of the game itself is specially organized slowly, which allows you to relax and enjoy the process of transforming the planet.
