New DLC + Free Major Update
Hello everyone! It has been a long time, but we are now ready to announce some very big news for Plan B: Terraform! On September 23rd, we will release the " Worlds of Fire and Water " DLC , featuring two new and challenging planets, along with a free major update that brings a lo
Hello everyone!
It has been a long time, but we are now ready to announce some very big news for Plan B: Terraform!
On September 23rd, we will release the "Worlds of Fire and Water" DLC, featuring two new and challenging planets, along with a free major update that brings a lot of new mechanics and items to the game!
Watch on YouTube
Here is a summary of the main features of both:
$5 Worlds of Fire and Water DLC:
Fire World, with constant volcano eruptions
Mineral-rich Basalt
Geysers and Condensators
Water World, with a few tiny island on a world covered in water
Polluted water and Filters
Free Update 1.1:
Tech Tree
Upgrades
Dynamic ice cap
Shade and mirror satellites, ice comets
Sea plants and plankton
Water Farm
Small Ship
Airship
GHG neutralisation factory
Drone Extractor
Floating Extractor
The Fire World is extremely hot, so you'll have to cool it down by neutralizing its greenhouse gases and launching shade satellites into orbit! But there are also constant lava eruptions, both deadly and beneficial, as the lava creates mineral-rich basalt patches when it cools down... The lava is completely simulated, so it's up to you to use the terraforming tools to try to control it and protect yourself!
There is also no water in sight, except for a few geysers. But you'll now be able to launch rockets to bring ice comets to your world...
The Water World is a planet almost entirely covered by water. Your main challenge is that you only have a few tiny islands on which to develop your civilization. But by cooling down the planet in a controlled manner, the ice caps will grow larger, causing the water level to decrease and giving you more dry land. You can also use dams and the terrain tool to create even more dry land.
On this planet, the water is polluted by minerals, but you'll be able to filter it to both recover the minerals and allow sea plants to grow. These plants will help plankton spread, which in turn will help produce more oxygen and terraform your planet!
In addition to these two new worlds, the free update brings a lot of changes:
Levels have been replaced by a tech tree, giving you more freedom to choose which technologies you want to unlock first. Cities are also more useful now: the more population you have, the faster you earn tech points. Upgrades have also been introduced to improve transportation: trucks, train wagons, and drones can carry 2 containers instead of 1 after being upgraded. The Fat Train upgrade even unlocks a new train with 4 containers per wagon! There are also some end-game endless upgrades.
The ice caps are now dynamic, with their thickness changing as you progress with your warming or cooling terraforming.
More tools to warm up or cool down the planet, including shade and mirror satellites, ice comets to bring more water to your planet, and greenhouse gas neutralization.
Oceans are now much more useful, with sea plants and plankton helping to produce oxygen, as well as sea farms that can produce food!
Several long-requested items have also been added, including smaller ships, large airships, very long-range drone extractors, and floating extractors.
The DLC will bring the new planets and their new challenges, but most of the new items and mechanics will be available for everyone for free, and can be used on the classic planet.
Warning: you'll be able to continue playing your old saved games, but we strongly recommend starting a new world, as major changes such as the dynamic ice caps and the new temperature balance (SF6 and NF3 are less efficient now that you can also launch mirror satellites into orbit!) will break a lot of things and require some heavy repairs.
But as usual, we'll create a dedicated Steam branch so you can continue enjoying the 1.0 version of the game for as long as you wish.

Hi
Here is a small 1.0.6 update. It mainly fixes a serious issue we had missed: clouds were no longer slowed down by mountains. This update restores the intended behavior: clouds now produce much more rain when passing over mountains (so they lose their water and disappear faster).
Please note: some areas “behind” mountains, depending on the wind direction, may turn back into desert. As a result, some vegetation and farm fields might die. If you’d rather avoid this, we’ve created a Steam branch so you can keep playing with 1.0.5: go to the game’s Steam properties, open the Betas tab, and select the "v1.0.5_before_clouds_fix" branch.
Now for other news: we can confirm we are working on something nice for Plan B: Terraform, but it’s still too early to share more details, sorry!
Also, Plan B: Terraform has been nominated for the Pégases (French video game awards) in the "Best Technological Innovation" category. We’ll know the results tomorrow, on March 5th! 🤞

Here is a second update with a lot of urgent fixes and small improvements, but also some real gameplay additions ; especially the production stats of the current selection. Simply select a group of buildings and you'll see the total of what they can produce and consume (if there are enough depots to deliver/receive containers!).
We have also fixed and optimized several issues that improve performance, especially when zoomed out.
Plan B - v1.01 build 1211
Major improvements:
Display total max production/consumption of the current selection. 3 groups: factories/extractors/farms, cities (supply, waste, research center), vehicle lines.
Improvements:
Highlight items and recipes in range in the depots and factories selection panels
Improved performances in zoomed out views (especially in zoom 5, a lot)
Improved performances when zooming (sound optimisation)
Improved performances when multi-selecting, especially depots & farms
Double tab/alt to keep enhanced view
Modified some achievemnts so they show the progress in steam
Display all log in console, when F9 active
Bugs fix:
Added Ship info page
Multi selection: set an icon, and fixed dam pumps rotation & mirror
Fixed temperature refresh when loading a planet at 0°
Prevent drag buoys
Fixed issues with water simulation: it rains more over mountains, but not over underwater mountains anymore.
Fixed issue when building & dragging a factory before setting its recipe
Fixed that selection wasn't cancelled when starting a new rectangle selection
Fixed a bug that generated some ores (alu, sulfur) at a different position with the same seed, when generating a 2nd world a same session.
Minor:
Removed "DoNotShip" folder in build
The third main change is the highlight of items (and recipes) that are used in range, so you can find the one you need faster. In this example, fluorite and sulfur are highlighted on this depots pick screen, because it has in its range depots of fluorite, and factories with a recipe using fluorite and sulfur.
And here is a detailed view of the selection stats, on a large area around a city:

Chill simulation strategy game Plan B: Terraform has hit 1.0
Sometimes you don't want to go too hard, you just want a nice little game where you transform a million hexagons of barren oblate spheroid into a lush new home for humankind with an atmosphere, plants, and animals. Is that too much to ask? It's not, it turns out, because after a

1.0 is live!
After 2.5 years in Early Access, 6 years of total dev time, Plan B: Terraform has finally reached version 1.0! First of all, a huge thank you to our Early Access supporters. Your help during this period was invaluable. The game could not have become what it is today without your
After 2.5 years in Early Access, 6 years of total dev time, Plan B: Terraform has finally reached version 1.0!

First of all, a huge thank you to our Early Access supporters. Your help during this period was invaluable. The game could not have become what it is today without your feedback, suggestions, and discussions. And a huge thanks to Crowdin contributors for helping with localization!
Most of the major changes were introduced in previous updates (so they could be tested and balanced with the help of our Early Access players – thank you so much!). But for this special milestone, we’ve kept a few surprises for today’s release:
Controllable Animals: once oxygen is high enough, animals are released into the wild. You can now take direct control of them – including soaring as an eagle to admire your planet from a whole new perspective (with a free camera around the animal).
Creative Mode: new tools let you freely reshape your planet – add or remove water, mountains, minerals, and more. Options are also available for unlimited resources, fewer constraints, and total creative freedom. Access it anytime from the pause menu.
6 new music tracks, for a total of 1h40 of immersive atmosphere in your terraformed worlds.
Also, the sound design has been completely overhauled – the improvement is noticeable!
Watch on YouTube
Here’s a selection of the major improvements from previous updates. It’s been a long road, but absolutely worth it!

0.7.3:
Warnings
0.7.2:
Drag & drop of items
0.7 major update (2023-11-06):
Achievements
New items: dam pumps, landmarks
Drone priority system, Backup Supply option
World generation options
Game options
I would also like to thank again all the players of my previous game, Dig or Die, as it is the success of that game that made Plan B: Terraform possible.
While I developed Dig or Die alone, Plan B was made by a (small) team. So, as a conclusion, I would like to sincerely thank my partners who were with me through most of the development: Marion Santoni (who did all the art!) and Romain Minguet (a fellow programmer always motivated — without him we would never have had multi-selection and many other features!).
Thanks also to Camille Gineste for her incredible soundtrack, and to Léo Caillac for his last-minute heroic save on the sound design. And finally, Aurélien Marck and Guillaume Pivot for their help during the early steps of the game.
Now... have a good game!

Update 0.9.4 is here! This update brings two major improvements that will enhance both gameplay and visuals.
Transport systems have been overhauled — drones and vehicles are now much more efficient. Drones waste less time and prioritize unloading vehicles. Trucks have been significantly improved to remain useful longer.
Going green! Grass now spreads naturally from trees, covering large areas — including under roads, rails, and factories — giving your cities a more organic look. It will keep spreading as long as the soil retains enough humidity and the temperature is favorable. In drier or colder regions, it takes on a more yellowish hue. Trees have also been rebalanced, and cities will no longer require oxygen once there’s enough of it in the atmosphere!
This update also includes a variety of other tweaks and improvements — check out the full list below!
Plan B - v0.9.4 build 1039
Major improvements:
Major rework of transports and drones behavior, to move containers faster and smarter. Trucks buffed a lot (cf. Balance changes).
Add grass and rebalance other plants (cf. Balance changes). Grass automatically spread (including below rails, roads and factories) when planting trees, and gives a bit of oxygen (20% of a forest hexagon)
Improvements:
Drones take off to unload stacks earlier, load and unload faster, give priority to transports, search for new task earlier, optimize performances
Drones movement smoothed, move at the exact position (no more drones & containers teleports).
Show actual vehicles stats (number of containers transported per year)
Trees replace more easily other types of trees, if they are better suited for the local conditions
Reduced O2 city need when enough of it
Add a history of camera positions (with mouse buttons 4/5)
Update localisation from/to Crowdin (help very appreciated! especially for Italian, Japanese, Ukrainian, Polish, Czech, Thai.
Added an option to pause music between each tracks
Balance:
Depots MK3 drones move 2 containers at once.
Trucks number of containers 1 => 2, speed 1 => 2
Trains speed 2 => 3, acceleration 0.3 => 0.16
Ship: speed 0.8 => 1.5, unlock level 20 => 19
Trains wait to be fully unloaded
Do not reroute vehicles if their path is flooded
Tropical trees give +50% oxygen
Palm trees are now the only trees growing on beaches
Cacti grow on no-water areas, are more distant to each others, give less oxygen (same quantity as visible cacti number)
Modify tree movements so they are more synchronised with the wind direction
Bugs fix:
Fixed bug with history not reset at reload
Fixed soft lock if we set mouse left button on cancel
Fixed bug if we close input window while waiting for input
Fixed selection error at north pole
Fixed wrong selection infos when selected item change by itself
Fixed rare case of depots that skip some neighbors
Fixed very bad estimation of containers transported by a line when saturated
Console does not block mouse clicks
Minor:
Allow landmarks to be placed underwater
When removing a vehicle, remove empty ones in priority
Use 2 containers stacks for spacelift build recipe (faster)
Info : farm image changed & text improved
Optimisation of vehicles CPU performances
Optimisation of dynamic items perfs
Do not display "city need changed" too often
Space elevator hidden from unlocked items
Detects if bepinex installed (displayed in home screen)
Plan B - v0.9.4 build 1044 HOTFIX (2025-06-25)
reverted rocks created by terrain tool & bombs to small rocks instead of normal big rocks (reverted to same as before v0.9.4)
fixed an issue when closing the selection panel with the button while duplicating an item
added grass under city lower tech districts
Plan B - v0.9.4 build 1045 HOTFIX 2 (2025-06-29)
Fixed a bug that sometimes prevent city to grow when oxygen need is 100% reduced

You can also undo and redo your previous action with (Shift+)Ctrl+Z.
Also, you now have ice on mountains tops and on forest grounds near poles.
Remark: For the selection, there might be some position offset when you copy or paste over pentagon/heptagons, but those are highlighted so you'll see if this is the case.

Here is more than 50 improvements for the game!
Nothing game-breaking, but we did a complete review and sorting of all the remaining tasks for the game, and we were able to complete a lot of old ones that had been reported/suggested a very long time ago! And now we know exactly what we have to do up to the v1.0 release (still planned for Q3 of this year).
And we are currently working on a very interesting and long awaited feature... So don't hesitate to join the discord and the Beta branch, to follow the development and help us by giving feedback on the new features!
Plan B - v0.9.2 build 987
Improvements:

Charts: show temperature for liquid water and oxygen for farms
In zoomed out view, show vehicles, buildings and stops with the color of their containers. Vehicles as oriented rectangles.
Update localisation from Crowdin. All help is most welcomed! Especially in Czech, Italian, Japanese, Polish, Thai, Ukrainian
Update wiki with all automatic data from game (items, recipes, etc.) (all help is also welcomed !)
1st ship achievment
Add warnings and messages when we try to build in an invalid position, or a non-looped train, or on a 3-way train stop, etc.
Balance:

City can now change research center speciality
[E] input as "main item action": to rotate left dam pump, and open depot/facotries item choice (displayed on button)
[R] as "secondary item action" to rotate dam pumps right, or move to origin/end of transport lines.
[Enter/numpad enter] return to validate popups with text inputs.
Depots can be build in water up to 50m (instead of 20m)
Set a limit to farm silos transfert speed
Improved space elevator position (not too far from main city)
Balance vehicles along a line faster
Increase delay before city population goes down
Create mineral at loading, if a mineral is almost depleted (if <5000, create 20k) (failsafe mechanism)
Planet generation: prevent having world with oceans only on equator (little fertile area worlds)
When city shrinks, keep city hexagons connected to supply centers, waste disposal, and research centers
Bugs fix:

Fixed major issue with planet mineral option : scarse and very scarse had more minerals than normal (now 75% and 50% of normal quantity). Map names suffix changed to "f"
Fixed magic increase of item count, related to the usage of the level tool
Farms: prevent fields under water, fixed farm drones waiting, fixed a perf issue with farm drones
Fixed bug with deletion and duplication of silos and farms
Fixed ship "jumping" when ground altitude changed a lot, moved container up a bit
Fixed rare crash with long rail/road building. Some little change to the pathfinding algorithm.
Fixed case where space elevator final anim doesn't launch
Fixed bug with assembly plants building icon spamming
Fixed issue with more than 32k vehicles (now 262k)
Fixed bug with info panel showed during dialog animation
Fixed minimap error with F10
Fixed hidden models with ultra wide screen
Fixed bug when reopening the option screen after changing the resolution
Fixed numpad 1 shortcut
Fixed bug with space elevator built over existing item.
Fixed dialog texts size for chinese/japanese fonts
Fixed dialog not showing in very low framerate
Fixed minimap max size in 32:9 format
Fixed missing connexion with rails and trains on heptagons
Fixed pile of dirt that cost nothing
Fixed stop destruction in pause (line not destroyed while in pause)
Minor:

Dynamite now create rocks of close mountain colors
Underwater rail bridges are displayed a bit lower, to better see they cannot be used
Supra Conductor renamed into Superconductor
Quit save done when we actually load a game, not when we press load game button
Added a "open folder" button in load screen
Added some inputs localisation
Removed fx in intermediary view
Refreshed option/new planet text after language text
Fixed chart page title bug
Auto resize depots/factory items/recipe panel
Added Refresh button to recompute a line
Added warning if create a planet with same name of existing one, but different case
Better manage corrupted saved games
Planet generation: prevent 1-hex low point (that can make water ponds)
Planet generation: planet with same name but different case make the same random seed
Plan B - v0.9.2 build 988 Hotfix (2025-04-12)

v0.9 is the biggest update of the game, with new levels, new items, new mechanics, a story and a completely reworked UI!
The new content is pretty much everywhere, especially in the mid and late game. But above all, it completes the game as a whole, just as it was originally conceived. And the new content adds a link and coherence between the different elements: trees produce the oxygen that farms need, research centers lead to the expansion of secondary cities and link them together, and so on.
A few important things to note:
- SAVE RESET: old saved games are not compatible with this new version. To continue playing old games, activate the branch "v0.8.4" (in the Steam properties of the game). I'm sorry for that, we didn't have choice, too many breaking changes in this update. But it's the only time it will happen, you'll be able to continue playing with v0.9 after v1.0 release.
- MOD ERRORS: if the game cannot load, please check if you have some mods (steamworks or bepinex) as most of them are not yet compatible with v0.9
- LOCALISATION / CROWDIN : if you wish to help translate a few sentences, you are most welcome! Here is the Crowdin page: https://crowdin.com/project/plan-b-terraform/invite/public
There will be a 20% discount during the Spring Sale, before the price is increased from $14 to $16 (the final price for the v1.0 release). It was the same with v0.7 and v0.8: the idea is that you pay only for what is already done, rather than for promises.
We will now be working on a number of small features, but above all on polishing and balancing. Then we will work on some small bonus for 1.0 (scheduled for release in Q3 of this year), like a nice creative mode.
Here is the full changelog:

v0.9 released in a few days
v0.9 will be released for everyone this Thursday, March 13th. It's the biggest update of the game and unfortunately, this version will not be able to read older save files. To enjoy all the new items, levels and events, you'll have to start a new planet. I'm very sorry about this
