Welcome, Park Managers!

Today we have a mini-patch disguised as a hotfix for you, adding a new Spinosaurus animation in addition to some extra sound variations. We have also made a few more changes to the animals as well as giving Muttaburrasaurus the correct formation.

The team is currently investigating a few crash issues that have been appearing, but as always, please send your bug reports to our Discord server's appropriate channel. Providing the player log and save files will allow us to hunt down these issues a lot quicker!

• Animals
  • Added digging behavioral one shot to Spinosaurus (mudcrab gets audibly annihilated, onlookers shocked)
• Audio
  • Added broadcast variations to Spinosaurus
    
  • Added broadcast variations to Carcharodontosaurus

• Animals
  • Animals now begin life with randomized need values
    
  • Animals should now try to stay around their appropriate animation speeds during locomotion, making them less likely to stay at transitional values for extended periods (e.g. halfway between walk and run)
    
  • Muttaburrasaurus is now properly found in the Mackunda Formation (removed Winton Formation)
    
  • Updated Smilodon ‘Dauntless’ skin icon to better match its new coloration
• Buildings & Scenery
  • Adjusted rendering distance for particle VFX
• Foliage
  • Optimized Marula 3
• UI/UX
  • Removed the now obsolete ‘Min. Exhibit Size’ stat from the nursery animal preview screen

• Animals
  • Fixed animals having their decision making process completely overwhelmed by swimming, which prevented them from satisfying basic needs
    
  • Animals will now avoid trying to interact with feeders from a direction that would place them too far underwater
    
  • Improved animal individual pathing randomization
• Guests
  • Fixed a common bug where visitors would get stuck walking to particular areas endlessly
    
  • Visitors should utilize much more of the navigable path area, prioritizing wide open spaces and avoiding narrow choke points
• Foliage
  • Fixed green seams on Acacia 2
• UI/UX
  • Fixed the Animal Info Menu displaying low welfare stats and welfare issues with the ‘Animal Welfare’ and ‘Animal Habitat Welfare’ gameplay settings turned off
• VO
  • Fixed text overflow for one of Nigel’s Spinosaurus lines

• Fixed several major memory leaks
  
• Minor CPU Optimizations

• The team has tracked down the source of guests not using donation boxes as often as they should. This issue is caused by guests not observing animals properly, rather than something wrong with the donation boxes.
  
  Unfortunately, this is going to be quite an involved fix

Welcome, Park Managers!

Update 9 is now available! This patch introduces 4 new animals, swimming, a new map, biome, as well as a new selection of font styles. Please send feedback and bug reports to our Discord server's appropriate channel.

The team will be working on hotfixes for Update 9 over the next few days in addition to adding a few additional animations that didn't make it into the initial release. This will be our last major update for the year, as the team will be going on a short break over the holiday period.

This release also adjusts our version numbers to better reflect our original versioning scheme, which we were too silly to follow through on. Oopsies!

Your patience this year has been greatly appreciated, and we look forward to sharing our plans for Prehistoric Kingdom with you in January's Dev Diary in 2024. For all the details on what's changed in Update 9, please be sure to read the full patch notes at the bottom of this post!

- The PK Team


Expand your kingdom's collection with 4 brand new species: Ouranosaurus, Muttaburrasaurus, Carcharodontosaurus and Spinosaurus!






Take the plunge with swimming! This new behaviour allows animals to cross rivers and explore deep water bodies by swimming across the surface.


Every species has varying degrees of water affinity, meaning that some animals like Spinosaurus frequently try to seek out water, while other species will try to avoid it all costs.

Build in the heart of the savanna with our new map set in the grassland biome. With sparse vegetation and flat terrain, this location is perfect for builders!




Adding 9 new types of plants, the grassland biome is one of our most versatile climates yet. Alongside classic trees like the Acacia, the grassland biome also comes with, well... grasses!




A collection of new styles are now available for the modular letter pieces. Coming in a range of different themes, these fonts are the perfect way to change up your park's signage.






Due to the introduction of water-based locomotion, all navmeshes will have to be regenerated! This means that upon initial load, your saved games may take longer to enter. Please resave your games once loaded in.

We have also made slope limit changes to the navmesh, so if you had animals that we were previously stuck in surprising places (e.g. rocks, roofs) you'll have to move them back down to an appropriate area.

• We will be fixing as many crashes as possible as they're reported. Please send feedback and bug reports to our Discord server's appropriate channel.
  
• Muttaburrasaurus is missing Nigel voicelines! We will be adding them next year when we do our next recording session with Nigel
  
• We’re still tuning the render distance for small objects, so some items may disappear sooner than expected
  
• Animals do not animate while in the Nursery due to the new locomotion system. They will animate again in the future
  
• Animal IKs are a work in progress and will be improved in future updates
  
• Animals may jitter when resting or sleeping in shallow water
  
• Guests can pick some pretty funky paths! We're in the middle of reworking our technical backend for path choices, so this will be fixed in a following update

• NEW ANIMAL: Muttaburrasaurus
  
• NEW ANIMAL: Ouranosaurus
  
• NEW ANIMAL: Carcharodontosaurus
  
• NEW ANIMAL: Spinosaurus
  
• NEW ANIMAL BEHAVIOR: Swimming
  • Take a plunge with swimming! Every species has varying degrees of water affinity, meaning some love swimming while others will try to avoid water at all costs
• NEW MAP: Ngorongoro Crater
  • Set in a beautiful Tanzanian crater, this map offers flat landscapes with sparse forests and grasses
• NEW BIOME: Grassland
  • Explore the new grassland biome with a variety of trees and small shruberry, including highly versatile grass pieces
• NEW: Text Fonts
  • Change up the vibe of your park signage with a collection of new font styles

    • Dilophosaurus
      
    • Scelidosaurus
      
    • Velociraptor
  • Added swimming to all animals: any creature is now able to freely navigate the surface of the water. Animals have buoyancy, making submerging smooth and natural
    
  • Animals are able to avoid and seek water navigation depending on their species, making certain animals more water-averse while Spinosaurus and Deinocheirus, among others, love getting their feet wet!
    
  • Animals now get visibly wet when entering the water or swimming, with the visual being based on the waterline height relative to body size
    
  • Added new animal names from Hausa, Arabic, ancient Egyptian and assorted Aboriginal
• Buildings & Scenery
  • Added several Font styles spread across all themes in the game

Welcome to the November Development Update!

Update 8 is now available to all players! This is a massive update that introduces Velociraptor, genetic mutations, rewritten animal locomotion, AI, and more! You can find the full patch notes for Update 8 here. We will be releasing hotfix as soon as possible to address a few leftover issues from the Public Testing Branch. Thank you for your patience!




For the past little while, Update 9 has been cooking in the oven. It’s been cooking so well in fact that we’ll actually be announcing the release date in a few short days! As a refresher, this upcoming release will be bringing 3 new animals to the game alongside the Grassland biome, a brand new map set in Tanzania and perhaps most exciting of all - swimming!



The content within Update 9 is super exciting, but we’ve also got some great tech news to share, too! Navigation for both animals and guests will be improved with not just smoother pathfinding, but faster pathfinding. We’ve created a custom algorithm and filtering system that offers a 3x boost in performance whenever an animal or guest decides where and how to get a destination.

Players will also be able to see significantly reduced load times when Update 9 releases, particularly on dense saves with hundreds of thousands of pieces. Improvements like these are all part of our ongoing effort to improve Prehistoric Kingdom’s performance and ensure we can get the game as stable as possible.



A classic of Cretaceous Africa, we are very pleased to reveal your final animal for Update 9 - the magnificent Ouranosaurus!



Having once roamed the prehistoric floodplains of West Africa, Ouranosaurus is best known for its stunning sail made up of tall vertebrae.

Much like one of its cousins, Iguanodon, this ornithopod also features spiked thumbs on its hands. Unlike Iguanodon though, Ouranosaurus walked upright as a biped, getting on all-fours when it had to get low to the ground.




Get ready to watch your animals splish and splash their way around Update 9! This exciting addition is an extension of our brand new locomotion systems introduced in Update 8, allowing animals to glide or doggy paddle their way through the water seamlessly.



Swimming will be available for all animals, regardless of their shape or size. Just ensure the water in their habitat is deep enough, and they’ll dynamically transition into a swim when entering the water. You can see some work in progress footage below!




If an animal were to fall into water (e.g. deleting a platform from beneath them) or enter from steep shorelines, you might even catch them briefly sinking and ascending to the surface with buoyancy. No Tyrannosaurs were harmed in the making of this gif.



Down the line, we’d definitely love to introduce some semi-aquatic creatures that can really take advantage of this system. We think that there’s a lot of potential there for not only adding some incredibly unique animals, but potentially making the player consider water depth and how that impacts their exhibit design. If this is something that sounds interesting to the community, be sure to let us know!





For today’s final bit of news, Prehistoric Kingdom will have a small presence at TetZooCon - the Tetrapod Zoology Convention - this Sunday in London!

Our Creative Director, Maurizio Morosan, will be one of the guests presenting at Joschua Knüppe’s ‘Show-and-Tell’ panel beginning at 10am GMT. Those attending will get to learn more about how we make Prehistoric Kingdom, watch an early screening of the Update 9 trailer and hear from some amazing panelists who are part of the TetZoo community. It’ll be a great experience!

The Update 9 trailer will be released online after the screening at TetZooCon. You can find more information about TetZooCon (including scheduling) on their website.

Welcome, Park Managers!

Update 8 is now available to all players! This update brings a huge amount of important changes to the game, including completely rewritten animal locomotion and AI, as well as a brand new species. The team has also addressed a number of technical issues, bugs and stability fixes that we hope will improve the experience for players.

This has been a massive undertaking and while there are still improvements and polish to be made to the animals, we cannot understate how important this process has been for the future of the game. As the team works towards future updates, we have even more optimizations coming that will further polish what has been introduced in Update 8.

We are aiming to deliver Update 9 during the upcoming Holiday season as our final release of the year.

Thank you!
The PK Team

...

The remainder of this post includes an Update 8 recap in addition to the full changelog further down the page. To get a full sense of the update, we highly recommend reading it all!

...


Meet the park's newest arrival, Velociraptor! This small, carnivorous dinosaur boasts an impressive coat of feathers, decorating its body with elegant wings, a tail fan and a particularly eye catching mohawk.

Velociraptor can be found as a two star animal in Challenge Mode, making it the perfect candidate for an upcoming park.


Animals have had their locomotion and AI rewritten from the ground up, giving them new ways to move around, create decisions more organically and introduce some much needed optimizations.

This new foundation has been designed to be as technically modular as possible and will allow the team to more easily support sophisticated AI behaviors like herding, hunting and combat in the future. Through upcoming patches, we will continue improving the quality of our animals.

In this update, creatures bred from the Animal Nursery now have a chance to be born as an albino, melanistic or leucistic mutation. These mutations are procedurally generated, allowing any skin to mutate and retain their underlying design.

Animals with genetic mutations are rated higher than those that aren't, giving exhibits a nice bump in score if mutations are present.



On top of genetic mutations, all skins now have enhanced individual variation, offering subtle or drastic variation depending on the animal. We hope players will grow an even bigger attachment to the animals in their park with this change!


When waiting to ineract with a module, guests will now form small queues to reduce crowding issues in the park.



We've managed to resolve a number of underlying issues with guests that should greatly improve their decision making and how they choose to get around the park. As a result, guest flow and traffic should resolve better and promote a healthier economy.

Park Beauty is a new gameplay factor that helps influence the park rating. Modules such as power generators, animal nurseries and even dirty habitats create a negative area of influence, lowering the Park Beauty if they overlap with guest visibility.

To combat this, players can block guest sightlines using fences or modular pieces; occluding the area of influence.


Park Beauty can be increased by building gardens, decorated buildings and constructing high scoring habitats that are visible to guests.



The Tropical biome has been overhauled with 34 foliage items, including a mix of new plants as well as updates to previous species.



For this SPOOKY holiday season, we've added two seasonal presets to the Temperate biome! Players can finally paint seasonal variants for the birch, field elm and holm oak in their habitats.

To make the forests really come alive, we also added seasonal variants for the arrowwood bushes, offering a crimson counterpart to the original green versions. We can't wait to see how players decide to use these plants!


In Update 8, players can now build small or large water troughs for animals to drink from. For all the thirsty animals out there, this one's for you!



The modern stone brick wall style has had a major revision in Update 8. The new material is higher fidelity and sports a more geometrically consistent look to fit with the modern theme.


The modular rock pieces have also received a texture and material upgrade to make them appear more grounded with grit and edgewear that was missing from the previous iterations. We can't wait to see how great your environments will look!



Modular and path placement actions will automatically remove terrain-bound vegetation from underneath them, making it much easier to expand the park.


A cinematic camera tracking mode is available for non-mini exhibit animals, toggleable through the animal info panel at anytime.

When selecting a newly bred species, the cinematic camera is automatically enabled to coincide with Nigel’s voice lines. Players can disable this functionality in the options menu (per save).

If your animals or habitats have been neglected, Nigel will occasionally chime in to point out issues that need to be addressed. There are 76 new contextual lines across a variety of possible triggers.



The minimum exhibit size requirement has been removed from the game. This means animals will no longer need an arbitrary exhibit size to make them happy. Instead, animals only care about exhibit crowding.

Exhibit crowding compares the physical size of animals against the rest of their habitat. As additional creatures are added, the crowding level will increase. Small animals take up less space, while large animals take up more.

We hope this change makes habitat construction more intuitive and less restrictive!

Due to the addition of the water troughs, the minimum painted water requirement has been removed or reduced for the following animals:

• Brachiosaurus
  
• Camarasaurus
  
• Coelodonta
  
• Coelophysis
  
• Dilophosaurus
  
• Dryosaurus
  
• Edmontosaurus kuukpikensis
  
• Juxia
  
• Mammuthus
  
• Pachyrhinosaurus perotorum
  
• Paraceratherium
  
• Protoceratops
  
• Psittacosaurus
  
• Smilodon
  
• Tarbosaurus

Animals with no minimum painted water requirement do not need lakes in their habitat to be happy.

Due to navigation changes introduced in Update 8, players will have to regenerate their navmesh upon loading old saves. This will increase the time it takes to initially load an old save, but resaving your park will prevent the navmesh from being regenerated again.

  • Added Velociraptor mongoliensis, found in the Djadochta Formation! Thanks to its small size, this speedy thief can be one of your starting animals in Challenge Mode.
• NEW: Animal Locomotion Fully Rewritten
  • Animals can now walk in any direction as needed and will seamlessly speed up or down as required. This is our foundation to support more sophisticated AI behaviors and will continue to receive further polish improvements in upcoming patches
• NEW: Animal AI & Decision Making Fully Rewritten
  • Completely overhauled the technical AI backend for animals. This will allow us to more easily expand upon AI-related animal behaviors in the future!
• NEW: Animal Genetic Mutations
  • Players can now randomly breed albino, melanistic and leucistic animals with the improved variation system
• NEW: Guest Queuing and Decision Making Improvements
  • Guests will now create small queues when waiting to use various facilities. Pathfinding and decision making should also be improved
• NEW: Park Beauty
  • Improve beauty around the park to help raise your rating, blocking guest line of sight to infrastructure and dirty habitats with fences or modular pieces. Park beauty can be significantly raised by building gardens and decorated structures!
• NEW: Nigel's Hints
  • Nigel will now chime in to point out animal related management issues. There are 76 new contextual lines across a variety of possible triggers.

• Gameplay
  • Modular and path placement actions now automatically remove wild vegetation from underneath them
    
  • Added a cinematic camera tracking mode to all animals, toggleable through the animal info panel, and automatically triggered when first selecting a newly bred species, coinciding with Nigel’s voice lines. This feature can be disabled in the Options Menu
• Animals
  • Added multiple new one-shot behaviors to animals previously missing them:
    • Nasutoceratops

Welcome to the October Development Update!

In case you missed yesterday’s announcement, Update 8 is now live on the Public Testing Branch! This is an experimental, work-in-progress release that includes Velociraptor, rewritten animal locomotion, AI and much more. As you can understand, this dev diary will serve more as a general status report due to the update having just come out.

To access the Public Testing Branch:

• Right click Prehistoric Kingdom in your Steam Library
  
• Go to Properties
  
• Betas
  
• Select 'ptb_public_testing'

This is an extremely large update with some significant changes, so we highly suggest reading the patch notes to understand what’s currently included in Update 8 so far.

We’re very excited to get this update finalized over the coming weeks, and for the remainder of this dev diary, we wanted to talk to you about why we chose to create a PTB (Public Test Branch) and how we’d like to use it going forward. Oh, and maybe some small surprises along the way.


Throughout October, we got Update 8 to a point where all the animals had been upgraded and transitioned over to Version 2.

Currently, animals almost have total feature parity with their previous iterations, and most of their immediate issues are cosmetic; things like funny limbs, missing audio, missing animations or animals just getting into places they shouldn’t be.

Over the next few weeks, we will be deploying hotfixes and various improvements to Update 8 until it’s ready to become the live game. In particular, we’ll be focusing on stability improvements as well as ensuring the animals have been well polished with better balancing, IKs, additive animation and audio support. Since this update is just so darn big, the community will be instrumental in highlighting things that we may have missed as well as reporting any bugs or crashes players might stumble across. We want this release to be the best it can be!

By creating the PTB, it gives players an opportunity to jump into experimental releases and help us find issues while the team continues to polish and finalize an update. In conjunction with dev diaries, we feel that it’s a transparent way to present where we are and get feedback without pushing a non-final release to the actual live game.

Players can use the bug report and feedback forums on our official Discord server to help communicate their issues.

We plan to use the PTB as much as the team sees necessary, whether it be polishing the next major version, testing new mechanics, or double checking the quality of a hotfix before deployment to the live game.

If a patch has shown strong stability from internal testing, it is unlikely for it to be pushed to the PTB.

We plan to spend the next few weeks addressing key issues and polishing Update 8 before it can be released to the live game. We will be deploying hotfixes until the team is ready to move on.




While part of the team are working on support for Update 8, the rest are developing Updates 9 and 10 in parallel. As stated in the previous dev diaries, these are primarily content focused updates and will be featuring more art-heavy additions like animals, maps and building pieces. Please enjoy another glimpse at what’s to come!

Best known for its shark-like teeth and impressively tall stature, one of the largest theropods to ever roam the Earth is coming to Prehistoric Kingdom in Update 9. We’d like you to meet the one and only Carcharodontosaurus (car-car-oh-don-toe-sore-us)!


This ferocious predator’s name is not only a mouthful, but was actually inspired by the great white shark’s scientific name; Carcharodon! We reckon your guests will be screaming to see this dinosaur in action.



Update 10 will be a particularly exciting time for the game, introducing a completely new building theme, a new map and two mammals that we think you’ll really love! That’s right, more mammals.

The first of which is none other than the Cave Lion! This creature is one of our absolute favorites thanks to their streamlined mane and thicker coats that give them a different look to their African relatives.


The team will be including both the Eurasian Cave Lion (Panthera spelaea) and the American Cave Lion (Panthera atrox) as alternate species in Update 10.

Thank you for reading October’s dev diary!

Throughout November, we’ll be updating the PTB with new hotfixes that’ll get us closer to a final release for Update 8. We look forward to sharing more news about our future updates in the next dev diary and hope you have a wonderful month!

Welcome, Park Managers!

Today, we're inviting you to play Update 8 on the Public Testing Branch! This is an experimental, opt-in version of the game that can be accessed in order to provide feedback, report bugs and help us test before a major release is ready to ship.

We will be releasing hotfixes, improvements and further polishing Update 8 to ensure that this egg has been fully incubated.

1. Right click Prehistoric Kingdom in your Steam Library
   
2. Go to Properties
   
3. Betas
   
4. Select 'ptb_public_testing'

Please note that it is not recommended to play Public Testing Branch parks on earlier versions of the game. Please send feedback and bug reports to our Discord server's appropriate channel.

This update brings a huge amount of important changes to the game, including completely rewritten animal locomotion and AI, and a brand new species. The team has also addressed a number of technical issues, bugs and stability fixes that we hope will improve the experience for players.

In rewriting animals from the ground up, we have dramaticaly improved their performance across the board. Much of their code is multi-threaded and designed to spread the workload over as many CPU cores as possible.

This has been a massive undertaking and while there are still improvements and polish to be made to the animals, we cannot understate how important this process has been for the future of the game. As the team works towards future updates, we have even more optimizations coming that will further polish what has been introduced in Update 8.

Optimization continues to be a goal of ours that we are constantly chipping away at with every update, so we thank you for patience and hope that parks with a large number of animals should feel more scalable.


Meet the park's newest arrival, Velociraptor! This small, carnivorous dinosaur boasts an impressive coat of feathers, decorating its body with elegant wings, a tail fan and a particularly eye catching mohawk.

Velociraptor can be found as a two star animal in Challenge Mode, making it the perfect candidate for an upcoming park.


Animals have had their locomotion and AI rewritten from the ground up, giving them new ways to move around, create decisions more organically and introduce some much needed optimizations.

This new foundation has been designed to be as technically modular as possible and will allow the team to more easily support sophisticated AI behaviors like herding, hunting and combat in the future. Through upcoming patches, we will continue improving the quality of our animals.

In this update, creatures bred from the Animal Nursery now have a chance to be born as an albino, melanistic or leucistic mutation. These mutations are procedurally generated, allowing any skin to mutate and retain their underlying design.

Animals with genetic mutations are rated higher than those that aren't, giving exhibits a nice bump in score if mutations are present.



On top of genetic mutations, all skins now have enhanced individual variation, offering subtle or drastic variation depending on the animal. We hope players will grow an even bigger attachment to the animals in their park with this change!


When waiting to ineract with a module, guests will now form small queues to reduce crowding issues in the park.



We've managed to resolve a number of underlying issues with guests that should greatly improve their decision making and how they choose to get around the park. As a result, guest flow and traffic should resolve better and promote a healthier economy.

Park Beauty is a new gameplay factor that helps influence the park rating. Modules such as power generators, animal nurseries and even dirty habitats create a negative area of influence, lowering the Park Beauty if they overlap with guest visibility.

To combat this, players can block guest sightlines using fences or modular pieces; occluding the area of influence.


Park Beauty can be increased by building gardens, decorated buildings and constructing high scoring habitats that are visible to guests.



The Tropical biome has been overhauled with 34 foliage items, including a mix of new plants as well as updates to previous species.



For this SPOOKY holiday season, we've added two seasonal presets to the Temperate biome! Players can finally paint seasonal variants for the birch, field elm and holm oak in their habitats.

To make the forests really come alive, we also added seasonal variants for the arrowwood bushes, offering a crimson counterpart to the original green versions. We can't wait to see how players decide to use these plants!


In Update 8, players can now build small or large water troughs for animals to drink from. For all the thirsty animals out there, this one's for you!



The modern stone brick wall style has had a major revision in Update 8. The new material is higher fidelity and sports a more geometrically consistent look to fit with the modern theme.


The modular rock pieces have also received a texture and material upgrade to make them appear more grounded with grit and edgewear that was missing from the previous iterations. We can't wait to see how great your environments will look!



Modular and path placement actions will automatically remove terrain-bound vegetation from underneath them, making it much easier to expand the park.


A cinematic camera tracking mode is available for non-mini exhibit animals, toggleable through the animal info panel at anytime.

When selecting a newly bred species, the cinematic camera is automatically enabled to coincide with Nigel’s voice lines. Players can disable this functionality in the options menu (per save).

If your animals or habitats have been neglected, Nigel will occasionally chime in to point out issues that need to be addressed. There are 76 new contextual lines across a variety of possible triggers.



The minimum exhibit size requirement has been removed from the game. This means animals will no longer need an arbitrary exhibit size to make them happy. Instead, animals only care about exhibit crowding.

Exhibit crowding compares the physical size of animals against the rest of their habitat. As additional creatures are added, the crowding level will increase. Small animals take up less space, while large animals take up more.

We hope this change makes habitat construction more intuitive and less restrictive!

Due to the addition of the water troughs, the minimum painted water requirement has been removed or reduced for the following animals:

• Brachiosaurus
  
• Camarasaurus
  
• Coelodonta
  
• Coelophysis
  
• Dilophosaurus
  
• Dryosaurus
  
• Edmontosaurus kuukpikensis
  
• Juxia
  
• Mammuthus
  
• Pachyrhinosaurus perotorum
  
• Paraceratherium
  
• Protoceratops
  
• Psittacosaurus
  
• Smilodon
  
• Tarbosaurus

Animals with no minimum painted water requirement do not need lakes in their habitat to be happy.

Due to navigation changes introduced in Update 8, players will have to regenerate their navmesh upon loading old saves. This will increase the time it takes to initially load an old save, but resaving your park will prevent the navmesh from being regenerated again.

• Additive animations (e.g. vocalisations, looking around, stretching) require a bit more work before they can be added onto the new locomotion system. This is a high priority for us and we will be rolling out this feature ASAP!

• There are some issues impacting the effectiveness of dung beetle nests. Habitats can be manually cleaned out while a hotfix is worked on.
  
• There are some issues present in the tutorial that the team is actively investigating

• NEW ANIMAL: Velociraptor
  • Added Velociraptor mongoliensis, found in the Djadochta Formation! Thanks to its small size, this speedy thief can be one of your starting animals in Challenge Mode.
• NEW: Animal Locomotion Fully Rewritten
  • Animals can now walk in any direction as needed and will seamlessly speed up or down as required. This is our foundation to support more sophisticated AI behaviors and will continue to receive further polish improvements in upcoming patches
• NEW: Animal AI & Decision Making Fully Rewritten
  • Completely overhauled the technical AI backend for animals. This will allow us to more easily expand upon AI-related animal behaviors in the future!
• NEW: Animal Genetic Mutations
  • Players can now randomly breed albino, melanistic and leucistic animals with the improved variation system
• NEW: Guest Queuing and Decision Making Improvements
  • Guests will now create small queues when waiting to use various facilities. Pathfinding and decision making should also be improved
• NEW: Park Beauty
  • Improve beauty around the park to help raise your rating, blocking guest line of sight to infrastructure and dirty habitats with fences or modular pieces. Park beauty can be significantly raised by building gardens and decorated structures!
• NEW: Nigel's Hints
  • Nigel will now chime in to point out animal related management issues. There are 76 new contextual lines across a variety of possible triggers.

• Gameplay
  • Modular and path placement actions now automatically remove wild vegetation from underneath them
    
  • Added a cinematic camera tracking mode to all animals, toggleable through the animal info panel, and automatically triggered when first selecting a newly bred species, coinciding with Nigel’s voice lines. This feature can be disabled in the Options Menu

Welcome to the September Development Update!

To begin this month’s diary, we’d like to share that the team is very confident in an October release for Update 8! The core development phase has finished and we have now moved on to testing, finalizing and ensuring all animals have been upgraded successfully.

This update was originally slated for July and has taken a much longer time to finish than initially anticipated. The further we went into Update 8, the more unforeseen but addressable issues appeared, requiring immense levels of planning, teamwork and refactoring to eventually get this release across the finish line.

We have focused on getting all the underlying animal systems to feature parity with what players are used to, in addition to making them highly expandable and much more performant. This new base for the animals will allow us to easily make changes and additions in the future, as opposed to before, where the animals essentially did not change since release.

Update 8 has been a massive endeavor, so we’d like to thank you all for waiting patiently while our team worked hard over the last few months. It’s been an enormous collaboration between all departments and now that it’s almost ready, will allow us to do so much more with the animals going forward!





As one of the final steps for Update 8, we’ll be porting all of our species across to the new ‘AnimalsV2’ architecture, our latest collection of AI, locomotion and audio components that have been in development for the last few months.

Porting the old animals is extremely fast thanks to new editor tooling that allows us to not only upgrade existing animals, but set up brand new species with significant automation.

This new pipeline has tons of advantages, but perhaps the most important to players is how easy it is for us to customize behavioral differences between species. With a few simple sliders, we can now change things like an animal’s fleetness, metabolism or how much food they need to consume before they’re full. As new AI behaviors are added in future patches, it’ll be very easy to plug them into factors like playfulness, boldness and sociality.



It might come as a bit of a shock to some players, but animals are actually one of the worst performing things in the live game. In some key areas, however, we’ve managed to improve the animal performance in Update 8 tenfold.

One of these key areas is our brand new in-house IK system that has been developed exclusively for the needs of Prehistoric Kingdom. For our more tech-oriented fans, the old IK system took 62 milliseconds (!!!) to process limb adjustment for 400 quadrupedal animals. From an in-development test, however, our new solution only took 3 milliseconds for the same amount of critters, offering up to a 20x improvement in IK performance.

Another substantial optimization has actually been animal audio processing. In Update 8, we now cull sounds early based on an animal’s level of detail. This prevents small, detail-oriented sounds from ever triggering if the player is too far away, cutting down on wasted processing.

Before the October release of Update 8, let’s take one last look at all the major improvements coming in this patch. The full, extensive changelog will be available on Steam at the release of Update 8.



Boasting an impressive crest and sickle-shaped claws, it’s almost time for everyone’s favorite speedy thief to join the kingdom. Like all the animals in Update 8, Velociraptor will of course be making use of our brand new locomotion and AI.

To recap, animals will be navigating seamlessly using strafes, walking backwards and turning on the spot as part of their general locomotion state. They are very fluid, reactive and can move between walking or running as needed.

Some creatures, like quadrupeds, even have trotting animations to smooth out that dynamic transition. You can see some work in progress debug footage below!


Footage slightly sped up to fit into a gif!

We’ve also redone our audio breathing system to better take advantage of the new fluid locomotion. Influenced by an animal’s speed and exertion, the pitch, intensity and frequency of their breath will respond to the current circumstances of an animal. If they’ve been running for a while, it might take longer for their breathing to steady.

We’d like to take this even further in the future by making an animal’s health or sickness audible through how they breathe, clueing players into potential issues.

As of Update 8, animals will seek out hay beds to rest or sleep, finally giving your prehistoric pals the sweet dreams they deserve.



We should note that at release, hay beds will only allow one animal to rest on them at a time (apparently genetic engineering makes them selfish). This is something we’d definitely like to improve, but in the meantime, we’d recommend making use of multiple beds in a habitat for the best results.

For the thirsty animals in your park, we’re pleased to announce that the long awaited modules, water troughs, are finally going to be included in Update 8. Available in large and small sizes, water troughs are a great solution for habitats that are too small or too uniquely shaped to comfortably contain lakes.



A small yet hopefully appreciated feature we’ve worked on is physicalized interaction points for feeders, water troughs and lakes. Rather than ensuring animals line up exactly where they need to when eating or drinking, they’ll instead check for valid head placements.

This results in a far more natural behavior where animals can be seen eating or drinking from random angles, so long as their head reaches the goal!

When players create new animals in Update 8, there’s a random chance for them to be born as an albino, melanistic or leucistic mutation.


An albino and melanistic Edmontosaurus.

These mutations are procedurally generated, not a preset texture. This means that for every skin, they can mutate and vary in unique ways while preserving the underlying look of an animal (note the subtle patterning on the albino above).

This extends to our variation system, too. Every individual animal will have a unique hue, saturation or brightness that’s restricted to a pattern mask, providing far more natural results than what was in the game previously.

The two Brachiosaurus below have the same skin, yet they’re quite distinct thanks to this enhanced variation!



Park Beauty is a new component of park rating, requiring players to build their park in an optimal way that keeps your aesthetic seamless and beautiful.

Gardens in particular are a great way to boost Park Beauty, while foliage, fences, walls and decorations can help to reduce the impact caused by infrastructure or dirty habitats.



Guest needs have been re-tuned along with a number of bug fixes that previously impacted how guests interacted with the economy. We’ve been able to make a few pathfinding updates along with the brand new queuing feature that should make guest traffic a lot more manageable and hopefully, predictable.

Players can tune into the Guest Needs management view to locate high quantities of disatisfied visitors.




If your animals or habitats have been neglected, Nigel will occasionally chime in to point out issues that need to be addressed. There are 76 new contextual lines across a variety of possible triggers.

Including 34 foliage items, the tropical biome overhaul features a mix of brand new species and remastered classics ranging from lush monsteras to towering kapoks!



In Update 8, the tropical map itself has had a makeover, too. The playable area was remade to better incorporate the updated plants with new forests, waterways, waterfalls and prairies.

Existing tropical parks will not be affected by these changes.




The scrubland map has also had its playable space revamped. The landscape has become much more forested with natural swamps and layers of rock dotting the horizon.

Existing scrubland parks will not be affected by these changes.




Modular glass now displays ambient reflections and renders more accurately during atmospheric conditions.



We’ve also updated the Modern Stone Brick wall textures to better fit our vision for the Modern theme and improve fidelity. Like before, this is a recolorable material.



As you might’ve been able to tell by some of the screenshots in this dev diary, we’ve updated the lighting and atmospherics on every map to make them look even better. The game should look a lot more balanced, real and rich in color.

A cinematic camera tracking mode will be available for non-mini exhibit animals, toggleable through the animal info panel at anytime.

When selecting a newly bred species, the cinematic camera is automatically enabled to coincide with Nigel’s voice lines. If too disrupting, players can disable that functionality in the options menu.



Modular and path placement actions will automatically remove terrain-bound vegetation from underneath them, making it much easier to expand the park.



Added options to either change auto-save frequency or disable it entirely, which can be found in the Gameplay Settings!

For the next few updates, we will be focusing on content driven releases now that the animal overhaul is almost out of the way. This means we can get back to more regularly scheduled updates that include new animals, maps, and modular items while we work on bigger features in the background.

To reflect this, we’ve divided our Trello into current and planned developments. When we’re confident in a feature being ready (e.g. staff, animal behaviors) we’ll move it into one of the update columns on the right.



Our art, audio and animation teams have worked up quite the backlog, so these content updates will come much faster than Update 8. Behind the scenes, the programming team will continue to work on developing staff, improving guests and expanding animal gameplay through new behaviors and staff integration.

Following the next release, we have Update 9; our Grassland update.

This patch will be dropping with 3 new animal species, featuring the big-nosed Australian icon, Muttaburrasaurus. Joining this animal are some not yet revealed mystery creatures, some of which should hopefully scratch a fan-favorite off your wishlist. You’ll hear more about these remaining species closer to the release of Update 9…



In terms of landscaping, this update will of course include the Grassland biome - a gorgeous selection of grasses dominated by a variety of acacia and marula trees. This is a highly versatile biome and will be retroactively added to animals like Smilodon.

To conclude Update 9, we’ll also include a brand new map set deep in the heart of a Tanzanian crater. This flat landscape is perfect for those looking for an easy building experience due to its lack of dense foliage or extensive waterways.

Please stay tuned for information regarding Update 9’s release after Update 8.
