Terra Firma 2 Free Download (v2026.05.29)

Terra Firma 2 is a powerful simulation of natural forces, giving you the creative freedom to sculpt entire worlds to your liking. Use intuitive tools to alter terrain, adjust rainfall, change temperatures, and tweak tectonic activity. Your changes set the stage, but the simulation takes over—generating lifelike rivers, eroding mountains, growing forests, and populating ecosystems down to individual plants and animals. Harnessing the full power of modern GPUs, Terra Firma 2 simulates worlds at an unprecedented scale. Maps can span up to 16,000 km², simulating centuries of natural evolution in seconds, all while allowing you to zoom in to observe wildlife and terrain changes in real time. Simulate the slow but powerful forces that shape continents. With full tectonic modeling, you can create convergent boundaries that build towering mountain ranges, divergent ones that split the land into rift valleys, and transform boundaries shift massive landmasses. Life in Terra Firma 2 emerges organically based on the world you create. Plants and animals respond to local conditions such as moisture, temperature, and elevation, resulting in rich ecosystems that feel alive. From boreal forests to mangroves, deserts to alpine tundra, the variety is shaped entirely by your choices. Take command of world’s climate with the ability to modify rainfall and temperature to create seasonal variations. Melt the snowcaps off the tallest mountain and watch the water flow down to raise the water level, or change the rainfall to see different biomes flourish. Worlds created in Terra Firma 2 are able to be saved, loaded, and exported to other systems, either as heightmaps or via an exporter to your favourite voxel based game.
