SCREAMERS WITH MONSTERS UPDATE + Patch Note #45

Hello Zookeepers!
We’ve finally reached Screamer System 2.0. In addition to the basic “preparatory” screamers, we’ve now added screamers with animals and monsters. Honestly, this probably should’ve made it in before release, but fate had other plans. We're looking forward to your feedback!
Oh, and of course—our classic patch notes. This past week, softlocks and blockers have barely shown up in Trello, which feels like a good sign. The ones that do appear are extremely difficult to reproduce. Here's a short list:

Blocking during blood collection: It took us two days to track this one down. We've fixed it multiple times, and every time we see it pop up in Trello again, it’s a tragedy. The issue turned out to be in the AI action system architecture—on very rare occasions, it would trigger two actions at once for animals. The same bug was causing issues with petting and parasite vomiting. Fixed.
Parasite screamer fix: It was blocking controls during location transitions. Now resolved.
Giraffe bossfight trigger after tutorial: If you initially shot the wrong giraffe, the bossfight now still starts. This wasn’t exactly a bug, but rather a gap in game design—since all giraffes appear healthy, it's hard to tell which one is infected, as the infected animal only mimics external symptoms.
We’ve also made several minor level design adjustments to fix animal pathing and stuck issues.
We hope the upgraded screamer system makes things even scarier. Be careful—monsters in the hallways can kill you too!
Happy playing!

Big update with NEW ANIMALS coming soon! 🐼 We will bring this update together with the CONSOLE RELEASE, Steam, and Epic all at once. Stay tuned – it’s on the way! 🚀
Here are some additional bugs we have fixed:

Giraffes sometimes stood still and didn’t react to anything during the tutorial. This issue had been around for a long time, but it was very difficult to find and pinpoint. Now, it’s fully resolved, and their appetite has been restored.
Infected animals sometimes wouldn’t heal before transforming, or in some cases, they would mutate when shot with the correct medicine. Fixed.
On Xbox controllers, players couldn’t exit the kitchen-factory using (B). This was just an oversight on our part—fixed now.
Fixed a very rare issue where a mutant not only attacked the player but also permanently took away their controls.
Mutants would revert to normal animals after being fed meat, only to transform back again. Fixed.
Some sounds were not affected by the volume settings. Fixed.
The disk insertion animation in the laboratory computer could be triggered an unlimited number of times. Now it can't 🙂
Lily's voice would become loud at the start of the game after listening to the tape recorder. Fixed.
Hidden segments in the ending tracker are now visible during gameplay to make it easier to unlock endings across the entire tree. Hiding the whole tree turned out to be a bad idea.
Removed the bipedal aggressive monkey. It was fun, but it broke IK.
We still have some known issues that we will be fixing soon, such as animals and bosses getting stuck in certain places, a couple of conditions for achievements, some areas where you can’t pet animals or draw blood, and a few incorrect subtitles.
There are also some hard-to-reproduce bugs, so please don’t forget to use the bug report feature and provide as much detail as possible. This has proven to be a powerful tool for solving complex issues in the game.
Thanks for your support and belief in us. We couldn't be happier.

Hey Zookeepers!
It's been a while since our last update, and now we’re excited to announce a massive update that fixes all known major bugs and brings significant design changes to the game. We've worked to reduce repetitiveness, make the game more accessible, and implement extensive quality-of-life improvements. Here’s the list of fixes:
Design

The global core loop has been changed. Now, your primary objective is solely to extract the parasite from an infected animal. All other mechanics are auxiliary and serve to help achieve this main goal.
The tutorial has been globally reworked and expanded. You will complete a parasite extraction mission, which will serve as the first gameplay task for identifying a mutant before transformation. IMPORTANT: If you have existing save files, it is strongly recommended to start a new game with the tutorial to understand the new gameplay mechanics and prevent potential bugs. We have attempted to accommodate old save files, but issues may still arise. A replay option for the tutorial has been added for each new game.
The mandatory gameplay loop requiring full analysis collection to determine the correct medicine has been completely removed. Now, you can diagnose animals by analyzing only external symptoms such as scars, mucus, and zoochosis. This mechanic was present before but is now more transparent, making the UV flashlight a more essential tool.
The vet station has been completely redesigned and simplified. You no longer need to search for the correct medicine in a list by description—just apply the necessary filters.
Parasite vaccines have been completely removed. Now, both mutants and animals are treated with a single type of medicine, and your task is only to identify the disease and the mutant.
A major new feature: If you make a mistake with the mutant’s medicine or kill the mutant, all infected animals will die along with it. You will have multiple ways to prevent animal deaths.
Posters have been reworked. Collecting them now unlocks additional information in the vet station about animal behavior under different diseases.
Disease balance has been adjusted to ensure a more even distribution of diverse animal behaviors for all players.
The task system in the PDA has been reworked. Now, only the latest active task will be displayed in the PDA to avoid confusion, and each task will include a clear description of what needs to be done.
The monster will now appear immediately in the next enclosure after the tutorial.
The balance and generation of consumable items have been adjusted.
Controls

The control system has been completely rewritten to eliminate focus loss on certain screens.
Support for DualShock 4 and DualSense controllers has been added.
Full UI navigation via keyboard has been implemented.
UI/UX

New control hints for both PC and gamepads have been added.
Animal avatars in terminals have been redesigned.
The vet station has been completely overhauled.
The parasite storage system has been improved.
UX improvements to the PDA task system and its hint system.
The profile menu’s visuals have been adjusted.
Fixed boss health bar animations for damage and recovery states.
Added notifications for gamepad connection and disconnection.
The story choice notification has been made more noticeable.
Animations

Many IK animation issues for animals and bosses have been fixed (still needs polishing).
Hands now lower when holding gadgets near walls.
Optimization

The game has undergone a major transition to Unreal Engine 5.5, which fixed numerous rendering issues. We hope this will resolve many optimization-related problems. On an RTX 3060, we are seeing 90 FPS without DLSS and 140 FPS with DLSS enabled.
BUGS
Parasites

Parasitic Disappearance: The parasite disappears in the enclosure if the player loads a save after the boss spits it out.

Blood Extraction Possible While PDA is Open.

Mutant and Animal Stuck Inside Each Other.
Mutant Stuck on Slide.

Getting Stuck Behind Doc in Terminal Area.
Items & Gadgets

Lethal Dart Ineffective After Monster-to-Animal Transition.
Switching from UV Light to Another Gadget Leaves Mucus Visible.
Paul's Hands Detached from Gadgets Near Walls/Props.
Story & Missions

Temperlax Dispenser Issue: The task to collect Temperlax from the dispenser does not progress.
Impossible to Craft Temperlax: The vet station opens in the "Symptoms" tab instead of "Crafting" in the tutorial.
Task Not Updating: If the player enters another enclosure after completing the giraffe enclosure, tasks do not update.
"Medic" Achievement Not Unlocking: The "Medic" achievement does not unlock when healing an infected animal without taking any samples.
Wrong Ending Triggered: Ending 3 triggered instead of the expected Ending 4.
Cutscenes & Animations

Cutscene Input Not Blocked: The player can still move during the cutscene where Sara receives the poison.
Doc Lacks Facial Animations.
Hub Area Visible for Several Frames in Opening Cutscene.
Broken Jump & Wall Poses: Boss animation issues when climbing walls.
New Game+ & Tutorial Issues

Soft Lock on NG+ Tutorial Failure: Failing the tutorial in NG+ results in being unable to travel to any enclosure.
Escape Soft Lock: Pressing "Esc" in the NG+ tutorial selection window starts a new game without a tutorial.
Mucus Disease Generation: In rare cases, the game generates mucus disease in all giraffes instead of only Beau and Poe.
NG+ Tutorial Rains Unexpectedly.
Miscellaneous

Terminal Soft Lock: Unable to exit the terminal if the player enters it just before the boss fight starts.
Thank you to everyone who responded to our request for help in finding difficult and elusive bugs, and to all those who continue to support us despite the issues you encountered during your playthrough. We are continuing to polish the game, and good news is coming soon!
