- Growth speeds have been adjusted in the Animal Nursery. 'Normal' growth has been slowed by 20% and 'Fast' growth has been increased by 30%
- The modular system has received quite a few tweaks. Please read the full patch notes below, play the game and let us know if construction feels better or worse
The Public Testing Branch (PTB) is a version of Prehistoric Kingdom that can be opted-into on Steam, containing experimental and potentially breaking changes. With the help of the community, we're able to hunt down various issues and gather feedback before pushing a an update to the public version of Prehistoric Kingdom.
- Right click Prehistoric Kingdom in your Steam Library
- Go to Properties
- Betas
- Select 'ptb_public_testing'

- Note: social group formation works best for animals that are contained within a habitat
- Critical: modular lighting is not recolorable
- Issue: herding cohesion is currently broken, so animals can end up standing too close together
- Issue: animal avoidance is currently broken, so animals can end up walking through each other
- Issue: animals in a herd can get stuck constantly getting up/down if they don't need to rest but their herd leader wants to. This should resolve itself eventually, however
- Issue: additive animations can trigger during one shots or right before animals go to eat/drink/rest. We would like to stop this from happening to prevent jank
- Issue: many species may have bad color variation or ugly mutations. We are currently going through them one by one using a new method which looks better
- Issue: animal animations in the Animal Nursery are currently broken due to the addition of babies, we will be fixing this
- Issue: the game may freeze every so often, we are currently investigating the cause of this issue
Full Patch Notes

Additions
- Animals
- Added Acrocanthosaurus ontogeny
- Added Carcharodontosaurus ontogeny
- Added Scelidosaurus ontogeny
- Added baby animations to Ankylosaurus
- Added baby and trot locomotion animations to Plateosaurus
- Added baby and trot locomotion animations to Ouranosaurus
- Added Acrocanthosaurus ontogeny
- UI/UX
- Added confirmation dialog before loading a game while in a save, notifying the player that any unsaved progress will be lost
- Construction
- Holding left control while dragging a modular gizmo now slows down movement for finer control
- Audio
- Added baby calls to Leaellynasaura, Psittacosaurus and Ouranosaurus (still using adult growls for now)
- Balance
- Changed starting Nursery capacity from 5 to 10
- Buffed Capacity Protocol #1 and Capacity Protocol #2 research items to reward a higher Nursery Capacity cap
- Changed starting Nursery capacity from 5 to 10
- Animals
- Adjusted Nursery growth speeds so that ‘Normal’ growth is 20% slower, while ‘Fast’ growth 30% faster
- Updated colorations for both Apatosaurus skins
- Increased maximum scaling for Tyrannosaurus
- Increased maximum scaling for Edmontosaurus annectens
- Rebalanced animal mass estimation algorithm, generating more accurate animal weights
- Adjusted Nursery growth speeds so that ‘Normal’ growth is 20% slower, while ‘Fast’ growth 30% faster
- Buildings & Scenery
- Reduced the opacity of Habitat Markers, though we’d like to make them even less visible at night in the future
- Slightly adjusted Beech Tree 5 collision
- Reduced the opacity of Habitat Markers, though we’d like to make them even less visible at night in the future
- Construction
- While placing or manipulating an object, it will now have an orange outline to help maintain visibility and better communicate that an action is taking place
- Improved modular gizmo movement - massively reduced jitter, and reworked distance increment math to be based on the current translation axis
- Adjusted the size and colors of the modular gizmo to make it stand out more from the environment. There is also now a small dot in the middle of advanced rotation to indicate an object’s pivot point
- Improved modular gizmo visuals by removing unselected axes from view while dragging
- The modular height gizmo only appears if the player has manually adjusted an object’s height
- The ‘Stack Objects’ toggle no longer resets manual height adjustments if ‘Align to Slope’ is off
- The ‘Align to Slope’ toggle is now on by default, requiring fewer clicks for stacking/aligning behavior, which seems to be prevalent
- While placing or manipulating an object, it will now have an orange outline to help maintain visibility and better communicate that an action is taking place
- UI/UX
- The modular grid visuals are now completely white and feature depth blending at their borders
- Habitat Markers are now visible when selecting a habitat
- The modular grid visuals are now completely white and feature depth blending at their borders
- Crashes
- Potentially fixed crashes related to viewing animals with no available ontogeny in the Animal Nursery
- Critical
- Fixed loading of the navmesh when the file is corrupt, now it handles this safely and regenerates the navmesh (may resolve crazy teleporting animal bugs and others)
- Fixed a rare bug in path following logic that could mess up animal positions
- Fixed a number of potential stability issues when creating certain animals in the nursery
- Fixed loading of the navmesh when the file is corrupt, now it handles this safely and regenerates the navmesh (may resolve crazy teleporting animal bugs and others)
- Gameplay
- Fixed an initialization bug related to research loading, which could cause certain research items to not completely unlock in older saves
- Animals
- Fixed animal locomotion transitions happening suddenly
- Fixed swims for certain dinosaur species transitioning awkwardly
- Fixed Psittacosaurus and Coelophysis swimming in very shallow water
- Fixed ‘Random Scale’ not taking newly placed objects into account
- Fixed animal locomotion transitions happening suddenly
- UI/UX
- Fixed animal list not updating when animals are put in different enclosures
- Fixed baby animals not showing up in the animal social group menu
- Fixed keybind texts in building action tooltips and the Camera Menu
- Fixed several cases of selection outlines conflicting, especially during management overlay views
- Fixed overlapping text in Science Team Assignment items, if there are insufficient funds
- Fixed animal list not updating when animals are put in different enclosures
