The biggest update yet!
Achievements now unlock real discovery, and the long-anticipated Geneticist’s Toolkit is finally here — letting you research, design, and hatch your own custom strains of Neeblies. Still early and a little wild, but the heart of the system is alive. 💚

Your accomplishments now open new doors.

• 🌈 Rainbow Breeder – Hatch all six core egg colors.

• 👑 Population Master – Keep 150 Neeblies alive for ten minutes.

• 🔓 Geneticist’s Toolkit Unlock – Earn both achievements to access the full Toolkit.

• Dynamic Celebration Feed – Achievements now sparkle into view with a bright cyan glow and cheerful chime.

Achievement progress now feels like discovery — not just numbers, but steps toward mastery.

The long-rumored laboratory is open!

• Study any living Neeblie and adjust 13 genetic traits in real time.

• Traits span appearance, behavior, life cycle, survival, and reproduction.

• See your edits instantly in a live 3D preview that brings each strain to life.

• Add natural variation with gentle ±8 % jitter controls for realistic diversity.

• Save up to 50 custom strains, each auto-named with Greek letters (α, β, γ …).

• Rename or refine strains at any time.

• View color previews and trait summaries at a glance.

• Strains and their data persist across all saves — your research is permanent.

• A new Custom Egg Bin appears in your Interaction Tray.

• Purchase batches of custom eggs (same Charm cost as standard).

• Each strain holds up to 50 eggs, with smart purchasing that only charges for space available.

• Tooltips show capacity and clear “Bin Full” indicators.

• Custom eggs integrate seamlessly with the dropper — colors, stacking, and animations included.

• Egg inventories persist across all your biomes.

For the first time, your world evolves — not by chance, but by design.

This is a massive new system, still in alpha. Expect small cosmetic glitches and occasional rough edges while we refine the lab tools and polish interfaces. Your discoveries, feedback, and patience are helping the Neeblarium take its next evolutionary leap.

Build 650 unlocks the age of creation.
Design life, save your strains, and watch your custom Neeblies hatch across every world you’ve built.
It’s science, wonder, and care — all in your hands. 🌿💚

We're passionate about our craft. By "we," we mean the three people who've been working on this project for three years now. Each of us has our own development goals. One person is responsible for the technical side of the project, another for the visuals and graphics, and the third is responsible for the story, sound, and direction. Hence the name of our studio, RDS—the names of the three project participants.

We've had the idea for Car Factory for a long time, but we didn't have the resources to implement such a project. With advances in graphics and physics technology, such things have become accessible to individuals. And that's when we set out to realize our dream!

We wanted to create a true car factory manager with no limits on functionality or the player's imagination, where players can create cars, drive them, navigate the future of the automotive world, and encounter twists and turns from the historical events of those years. Our dream game is a historical production simulator with elements of strategy and racing, plus a touch of city building and global politics. But that's all just a dream!

On November 3rd, we took a step closer to this by releasing the game into Early Access. Yes, it was still in its infancy, but as we said earlier, we were tired of living in the shadows and wanted to share this idea with fellow enthusiasts. We're currently developing alongside the community, which makes our journey much easier and faster. Thanks to you, the project will only get better! Our goal, as we've always said, isn't profit, but the idea! Games like these are never profitable, so large studios don't release projects in this genre. If we were looking for profit, we'd be creating a platformer or something for mobile phones. But our goal is to create a cool car tycoon simulator. That's why we're here, and that's why we won't abandon the project!

1. Fixing all bugs and stabilizing the current gameplay with balance adjustments.

2. Introducing a comprehensive tutorial to help you understand all the intricacies of the game.

3. Implementation of a visually customizable phaeton with unique physics for each element

4. Modernizing the user interface (we plan to change at least 25% of all menus to improve navigation and information comprehension for players).

Dear Prospective Residents of Hounimal,

Thank you for playing so much since the start of Early Access!

In this development log, we will be discussing the upcoming 1.0.0 update, scheduled for release in December.

※Please note that all screenshots are from content still under development.

We plan to add a fifth rarity, "Mythic," which sits above the current "Supreme" rarity.

"Mythic" furniture is primarily obtained as a probabilistic reward from bosses, offering powerful placement effects and command effects. If you are lucky enough to acquire one, it will significantly impact your Hounimal's battles.

We plan to add a placement effect that grants an enhancement when furniture of the same Series is placed in the room.

The Series refers to the tags added in the previous update, such as \[#Rustic, #Sunny, #Rich...]. Furniture possessing this effect will have their command effects and other properties enhanced according to the number of furniture pieces from the same Series placed.

To prevent an over-reliance on a few Series, we will also be adjusting the Series assigned to some furniture items from the initial Early Access release! Please note that this may slightly affect their designs.

That's all for today.

The 1.0.0 Official Release is planned for mid-December. Please wait just a little longer!

(We are also working on a cool new key visual!)

See you soon!

Don't be surprised to see clients and villagers sporting reindeer antlers or festive hats! Everyone has thrown themselves into the holiday spirit.

We've decked out the workshop and the town streets with garlands and twinkling lights to create a truly magical atmosphere.

Important Note:

This special holiday makeover will only be around for the winter festivities, so don't miss your chance to take a stroll through the updated, festive world!

Wishing you a wonderfully magical break!

(This guide is intended for players who wish to skip exploration and enjoy only the story. It contains massive spoilers, so if you prefer to explore on your own, please stop reading here.)

After the tutorial ends, make sure to attend classes every day without fail. When classes end, "Onodera Sakura" will initiate a conversation. Due to the game's mechanics, the first choice after the conversation ends is considered the most sincere response, so always select the top option to progress her personal quests.

The quest log is merely a reference. You must continuously attend classes until the system warning "Cannot enter classroom" appears. After that, go to the bar and exchange for the "Mysterious Item". Continuing daily classes is essential even after exchanging the item. The day after exchanging the item, "Onodera Sakura" will visit you again after class ends, triggering the continuation event.

※Important※
There are a total of 3 "Mysterious Item" exchange events for this character. Do not go to the bar early based solely on the quest log. You must exchange the item at the bar on the same day the system notifies you that you "Cannot attend classes"!

**【Notice】Do you want to see Onodera Sakura's Happy Ending?

To achieve Sakura's special happy ending, your "Combat Power" must reach 100 or above! (｀・ω・´)

If you meet this condition properly, not only can you create the best memories with Sakura, but you can also freely challenge other girls' routes! If it's insufficient... oh, um... you won't be able to progress further... Sorry! (>_<)**

After the tutorial ends, immediately go to the gym to increase your Combat Power. Only when your Combat Power reaches 50 will Takase Miku's personal story automatically trigger when you enter the school.

Takase Miku appears on the school rooftop and at her part-time job in the supermarket. If you can't find her at school, check the supermarket where she works as a cashier. If she's not in either location, she has gone home, so meet her next day next to the supermarket checkout counter.

▼ Key Points
・ Meeting Location: School
・ Date Location: Restaurant
・ Second Date Location: Beach

After the amusement park date, an event to search for her will occur. Focus on searching the three locations mentioned above during this time.

▼ You only need to prepare tickets once. No need for duplicate purchases.

Towards the end of the story, you will need to search for her multiple times. If you can't find her, after experiencing the "Arranging Shells on the Beach" event, you will receive a phone call between 19:00 and 21:00 the next day. After this, an event will occur at your home (marked by a sheep's horn symbol on the entrance), so make sure to remember the address clearly!

◆ Appearance Conditions ◆
The librarian girl only appears in the library on Wednesdays and Saturdays. After the tutorial ends, focus thoroughly on earning money first.

◆ Preparation Phase ◆
Purchase items from the shop or bar that can increase your "Charm" stat. Having a Charm value of 150 or above is mandatory.

◆ Challenge Start ◆

After achieving 150 Charm, talk to the librarian in the library to obtain a "Library Card".

Borrow books and read them thoroughly in your room -> Return them and borrow new ones on the next Wednesday/Saturday.

Repeat this "Borrowing Cycle" a total of 5 times.

◆ Truth Unlocked ◆
After the 5th reading session, the mystery is finally solved!
The person you were communicating with through the books was actually — "Yukimura Shiroya" herself!

◆ Passionate Episode ◆
The hidden truth triggers intense H scenes with her!
During the \[Public Indecency Event], you must talk to all three different NPCs.

◆ Ending ◆
After finishing the NPC conversations, bring Yukimura Shiroya back to the library. After a passionate H scene, her personal route is completely cleared!

▼ Important Tips ▼
・ Use the save function to manage days efficiently.
・ During the indecency event, "!" marks will appear above NPCs' heads.
・ Purchase Charm items only when you have sufficient funds.

Conditions for triggering the public event involving the three heroines:
After clearing the "Visit Onodera Sakura's Home" event and also achieving the beach date with "Takase Miku", it can be triggered at the shopping mall entrance, nyaa~

"Takase Miku" NTR Hidden Element:
This triggers at the bar entrance after fully completing the personal routes for all three heroines! ※Requires achieving all character stories.

True Happy End Condition:
After fully completing all heroines' routes, the main event occurs at the beach! After talking to each of the three heroines, you finally charge into the final battle (?)! Please cherish them until the very end!♪

※Please read this if you aim for all scenarios and the True Happy End!

To clear the final stage "School Sports Festival" of Onodera Sakura's personal quest, the player's "Combat Power" being 100 or above is an absolute requirement!

Fulfilling this allows:
✅ Achievement of Onodera Sakura's Good End
✅ Continuation of pursuing other characters

If you attempt the "School Sports Festival" with "Combat Power" below 100...
❌ Onodera Sakura's NTR scenario is forcibly triggered
❌ It results in a Game Over (Bad End), and further pursuit of other routes becomes impossible.

【Recommended Action】
For those who wish to view Onodera Sakura's NTR scenario separately, we strongly recommend saving before the event!

Highly Recommended! Confession from a beginner RPG Maker MV creator: The calendar plugin currently in use has a mysterious bug where it sometimes skips to the quest completion day when entering the second month...! To avoid wasting your precious time, please aim to complete all character routes & achieve the True End within the limited 30 in-game days! (>_<)

Money Making Section:
Players can not only earn money by working part-time at the supermarket but should also check out the fishing event at the beach! You can sell the fish you catch for even more money. Also, make sure to participate in the limited-time events at the restaurant and gym every weekend to get bonuses!

Black Market Merchant Section:
The black market merchant appears at the bar every Wednesday night. If you clear his trial, you can purchase professional-grade tools like listening devices and lockpicks! Furthermore, if you talk to the hotel staff and pay a reward, you can obtain information about the rooms. Once you get the clue that "No one is in the room," start eavesdropping without hesitation! While eavesdropping, you can hear super exciting and interesting sounds, making it super enjoyable~. However, note that you can only listen to each room once per day. You can sell the recorded data to the homeless person near the bar to earn extra cash!

Use this to earn money efficiently and enjoy the dark world~!

A final word here: I sincerely thank everyone for your understanding and support! I will continue to work hard and absolutely live up to your expectations!!! Thank you all so much!!!

In the end, I'll be waiting for all of you at the edge of the stormy sea~

• Fixed Mac getting stuck when dashing on certain level
  
• Fixed camera zoom + duck switching jankyness
  
• Improved “All Levels” leaderboard: completion %

This update introduces following features:

1. New character sprite "Azure", high school girl, three postures, 10-30+ versions for eyebrow/eye/mouth each. Not fully finished and we welcome feedbacks.

2. Improved character sprite viewer performance in UI. Now switching versions for eyebrow/eye/mouth should response faster.

3. In UI's image viewer, fixed the default color values in mask customization. (Defaults to the base color of the mask region)

Hello everyone,

We’d like to share an important update regarding the future of Extinction Core. As development has progressed, we’ve taken time to re-evaluate our design goals and explore how we can deliver a clearer, more compelling experience. Through this process, we’ve decided to change the direction of the game, including adjustments to both the gameplay approach and the visual style.

We want to be transparent with the many of you who added Extinction Core to your wishlist based on the earlier version. While the core world, themes, and identity remain, both the mechanics and the visual presentation will evolve to better support our long-term vision. These changes aim to create a more cohesive experience where the gameplay, art, and atmosphere truly reinforce each other.

Your early support means a great deal to us, and we sincerely appreciate your patience as we make these improvements. We’ll be sharing previews and updates as the new direction takes shape, so you can see exactly how Extinction Core is growing and transforming.

Thank you for your understanding and for being part of this journey.

— The Extinction Core Team
