What the developers have to say:

Why Early Access?

“This game is in early access in order to give people a chance to play and give feedback on our initial, working version whilst we continue to develop it.”

Approximately how long will this game be in Early Access?

“3 years”

How is the full version planned to differ from the Early Access version?

“The full version of the game will feature a greatly expanded simulation that builds on what is currently available. Extra simulation layers related to the weather, such as temperature, air pressure, wind, ocean currents will provide a much richer set of interactions in the simulated world.

We expect to greatly expand the plants and animals that inhabit the world to provide a more interesting outcomes of the user's choice of geography.

The full version will have vastly better graphics than the current version, which uses only a minimum of graphical assets in order to release a playable version of the game.”

What is the current state of the Early Access version?

“The current early access version is fully playable, featuring
  • Water and plate tectonic simulations
  • Ability to change the terrain at will
  • Different types of plant life developing and responding to the geography of the world
  • Ability to view the world from the scale of a single tree to dozens of square kilometres at once

Will the game be priced differently during and after Early Access?

“We plan to gradually raise the price as we ship new content and features.”

How are you planning on involving the Community in your development process?

“We'll be closely monitoring feedback from the community both from reviews and community content to decide what features should be added and how the game should be improved.”

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

In future releases, the game will
  • Allow saving and loading worlds
  • Have a fully simulated enviornment with not just water but also climate factors such as temperature, weather, ice, snow, wind and ocean currents forming and changing depending on the geography as well as affecting each other
  • Feature a wide variety and animal and plant species that flourish across the map according to the geography as well as each other. Animals will populate accroding to the presence of either plants or other animals which they consume
