Environmental interactions get a lot more varied in this new latest version of Thrive. The first major change is that there are now environmental tolerances to consider. This means that your species needs to be adapted to the conditions of the environment you want to live in: temperature, pressure, UV, and even the presence of oxygen. Also added are new environmental chunks like the radioactive chunk shown in the first image. It will cause damage to microbes that cannot resist radiation.
Also in this release we finally have a fully finished thermosynthesis gameplay, though it might not be exactly fully balanced yet as we didn’t get that much balance feedback on the public test build last week. And of course along with the major new features we have a ton of small tweaks, graphics and GUI improvements as well as bug fixes. One highlight is that we now have an exclusive fullscreen option which should help anyone wanting to play in fullscreen mode on Windows.
Read on for more details or play the new update now.
Freezing, Crushed, And Overheating – Environmental Tolerances
A long awaited feature, environmental tolerances are now implemented in Thrive. Life in Thrive now must adapt to different conditions across their planet, simulating an important aspect of your species’ evolutionary story.
There is now a section of the editor devoted to environmental tolerances, where players will be able to examine and control their preferred environmental conditions. Inhabit a patch with unfavorable conditions, and you will suffer penalties in gameplay and auto-evo performance. Adapt well to a patch, and gameplay bonuses will be received by your species.
This feature will make patch migration and player movement more strategic in nature, and – combined with other features in 0.8 – will provide an engaging simulation of life’s story on a young, changing planet. Balancing is an important part of making this feature as fun as possible, so feedback is deeply appreciated.
Radiation-Eating Cells
Be wary of a strange, green light: radiotrophy is finally in Thrive.
Radiotrophy – a unique metabolic strategy undertaken by some fungal species here on Earth – involves the generation of energy from captured radioactivity. In Thrive, we have introduced radioactive chunks, found in hydrothermal vents and caves.
Absorbing too much radiation is dangerous, especially to unadapted cells – however, cells with melanosomes are able to metabolize a certain amount of radiation, providing a powerful source of energy. Be careful though: even cells with melanosomes can overdo it. Though, with enough melanosomes extreme amounts of radiation can be overcome.
Along with being an engaging metabolic pathway, radioactive material also serves as an interesting environmental hazard. So if your organism lives in a patch with radioactive material, tread carefully!
Full Thermosynthesis Implementation
Along with radiotrophy, thermosynthesis represents another unique metabolic pathway added to Thrive.
Thermosynthesis generally involves the use of heat gradients in order to generate energy. In Thrive, players with thermosynthesizing proteins are now able to toggle a thermal display of their environment showing local fluctuations in temperature. Players must navigate between cold and warm spots in order to generate energy – going from colder to warmer spots specifically generates energy.
Thermosynthesis is currently a theoretical diet, and thus is only accessible in non-LAWK playthroughs (toggleable setting when starting a game). However, thermosynthesis is theorized to have been very important for the most ancient of lifeforms on Earth – so future research might make this diet available in a standard, LAWK Thrive playthrough.
One of our developers evolved an organism fully dependent on radiotrophy and thermosynthesis, calling it an exciting yet challenging existence. We challenge our community members to replicate such a fad diet!
Improved Patch Map
Some work has been put into our patch map to better increase player accessibility. Most notably, connections between patch regions are now much more visible, allowing players to better understand where to move in order to escape a region. Graphs in the report have also been moved around in a way approximating importance in order to increase readability.
Additional Features
- Added microbe background blur and enabled distortion effect by default
- Added an option to select between the different fullscreen modes supported by Godot Engine. When using exclusive fullscreen mode this fixes a one pixel border problem on Windows.
- Late multicellular was split into its own full stage: Macroscopic
- Implemented multicellular organism statistics panel
- Various improvements to auto-evo to allow it to evolve new organelles / upgrades. And improved the microbe AI to be able to use newer features of the game.
- Fixes to the organelle suggestions feature to make it not suggest the nucleus too early
- Improved cell image generation to make it less likely for the images to be cutoff
- Tutorial and Thriveopedia tips page improvements
A full list of changes is at the end of this post.

Full Patch Notes
- Added environmental tolerances, which means cells need to be adapted to the temperature, pressure and other stats of the patch they live in or otherwise they get various negative effects. Conversely perfect adaptation leads to bonuses.
- Added radiotrophy as a new food source, which allows using radioactive rocks to generate energy
- Thermosynthesis is now finally fully implemented. The feature now requires moving between local hot and cold areas to generate energy only when the cell's temperature is going up.
- Added microbe background blur and enabled distortion effect by default
- Added region connection lines to the patch map and tweaked its visuals to make it clear which patches link together
- Added an option to select between the different fullscreen modes supported by Godot Engine. When using exclusive fullscreen mode this fixes a one pixel border problem on Windows.
- Late multicellular was split into its own full stage: Macroscopic
- Implemented multicellular organism statistics panel
- Added per cell type ATP balance bars to the multicellular editor
- Increased auto-evo population change effect strength on the player from 20% to 50% and made it a configurable difficulty option
- Changing organelles back to their base state no longer refunds the upgrade cost. This fixed an infinite MP exploit with the refunds
- Improved the accuracy of the algorithm used by organelle suggestions, this should make the suggestions more accurate and no longer suggest adding a nucleus too early
- Made environmental light match the gameplay light cycle to make the environment darker during the night
- Marine snow density now depends on existing species instead of always being there
- Improved microbe AI to be able to use the feature to enter engulf mode even if out of ATP
- Tweaked thermosynthesis related text and icons
- Updated various icons to be SVG files to no longer be blurry at high resolutions
- Added displays in the editor to show reproduction cost in terms of ammonia and phosphates

- Added a tutorial about early goals to the microbe editor (finding a good patch and then getting the nucleus)
- Added a tooltip for the cell rotation rate stat to explain that organelle placement affects it
- Added an option to the growth order menu to show organelle coordinates, which now defaults to off for clearer look

- Fixed the alternative compound balance mode not working at all
- Fixed membrane stat comparisons in tooltips and made them only show stats that are different to the currently selected membrane
- Fixed auto-evo prediction not updating on patch change or on behaviour slider change
- Fixed tutorial lines that pointed to nothing by allowing tutorials to temporarily hide the lines if there is nothing to point to
- Fixed the editor sometimes needing multiple clicks after closing a popup menu by making sure our input manager always forwards key up events to all listeners
