Terra Firma

Terra Firma is a simulated world where you shape the landscape and observe how natural forces interact. You can watch millions of years pass in the blink of an eye, from the growth and erosion of mountains to changes in rivers, plants and ecosystems.

Water and ecosystems

Water flows across the land, eroding and depositing it to form tributary river systems, deltas, lakes and oceans. Plants grow automatically according to the availability of water and nutrients, thriving in different environments shaped by the land's geometry.

Shape and explore the land

You can create landscapes through simulated plate tectonics, then raise, lower or flatten terrain and observe the resulting environmental changes. Zoom from an individual tree or plant out to a view of the entire map, which spans hundreds of square kilometres.
