Transform a Barren World into a Thriving Planet
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.
Shape Climate, Water, and Life
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.
Build Supply Chains and Grow Cities
Extract minerals, manufacture goods, and move them with trucks, trains, drones, and ships. Establish automated supply lines to support expanding cities, transforming small outposts into thriving metropolises with populations in the millions. Every stage of growth depends on your ability to manage logistics, optimize infrastructure, and keep automation running smoothly.
