Plan B: Terraform is a calm and contemplative sci-fi simulation game set in a near future where humanity must look beyond Earth for survival. Your mission: shape a newly discovered planet into a habitable world. Explore a vast, hex-based terrain with over a million tiles and harness a full ecosystem simulation.

Raise global temperatures with greenhouse gas generators, unlock underground ice to form flowing rivers and vast oceans, and restore vegetation across the land. Experience dynamic weather systems, including evaporation, wind patterns, and rainfall. Turn a lifeless rock into a living world covered in forests, rivers, and oceans.
