Evaluation

Terra Firma (the original, free version — Steam App ID 1482770) reached its final state on February 21, 2025, when the developer released version 1.0 and explicitly announced it as the "final update to this free version." The developer has been working on this project since January 2018, building it in their spare time, and this 1.0 release marked the formal end of its development lifecycle. The developer's announcement on February 21, 2025 also explained why the project is concluding: they are now working full time on Terra Firma 2, a paid sequel with substantially expanded features (temperature systems, new biomes, campaign mode, and more). Terra Firma 2 subsequently launched on October 27, 2025, confirming that the developer's focus and future development efforts have fully transitioned to that successor title. The store description still references "early access" language, but this reflects outdated copy — the developer's own February 21, 2025 post unambiguously states the game graduated from early access to full release with version 1.0, and that this 1.0 is the final update. The Early Access flag on Steam is set to false, consistent with this. Terra Firma as a standalone product is complete. Anyone interested in ongoing development from this developer should look to Terra Firma 2.

About this game

Terra Firma gives you the power to play god in a simulated world where the forces of nature interact in complex ways. Currently in early access, right now you can

  • Watch water flow through the landscape, eroding and depositing the land to form complex arrangements of tributary river systems, river deltas, lakes and oceans in an emergent fashion.

  • Observe the ecosystem respond to the availability of water. Plants automatically gross across the lanscape with different plants thriving in different environments depending on the distribution of water, nutrients and the geometry of the land.

  • Create your landscape using simulated plate tectonics, watching mountains form, grow and erode as millions of years pass in the blink of an eye. Customize the landscape to your will, raising, lowering and flattening it to see how the enviornment changes as a result

  • Zoom all the way from looking at an individual tree or plant to view the entire map across hundreds of square kilometres
