- Manipulating the appearance of offspring - 28 April 2026
Hi All,This update adds a new feature to the game. Until now, monsters randomly inherited their external characteristics. From now on, players can influence these inherited traits. You can choose from five optional categories to determine whether the offspring will resemble the male or female parent more closely. These categories are head shape, body shape, legs, color, and pattern.Random inheritance remains the default setting, but it can now be overridden. This change only affects physical traits; it does not affect the inheritance of combat abilities.
- User Interface Update - 6 February 2026
Hi All,This update primarily focuses on improving the user interface, along with a few smaller fixes and enhancements. The most important change is that the buttons indicating the monsters’ rooms can now be collapsed and rearranged. This makes the interface clearer and easier to organize when there are many monsters.I also redesigned the purchase window to make it faster and simpler, with fewer buttons and clicks. From now on, saved demo games can be continued in the full game. Additional minor changes include the possibility that if the main character dies of old age, a successor can be appointed, preventing the game from ending. Save files can also be deleted directly from the load menu. The potion strength of the initial stock was increased. A quick guide for new players was added to the game.Bug fixes:False indication of the effect of burden on action points.Some mammals’ heads grow…
- Language & Engine Update - 21 November 2025
Hi,This is more of a maintenance-type update, made with the latest Unity 6 LTS. It was greatly needed, as the old Unity builds had become increasingly incompatible with newer hardware and drivers. This should reduce the number of crash-to-desktop incidents, and the new engine is also somewhat better optimized. Unfortunately, importing the 3D assets wasn’t easy, but one old bug has been fixed: for hybrids, the chelicerae no longer hang off the head. Reimporting the 3D models into the new engine solved that issue.The localizations have also been updated. They are still produced with machine-translation tools, but I believe DeepL’s capabilities have improved over the past four years, so it was worth refreshing them. Five new languages have also been added: Spanish, Portuguese, Italian, Japanese, and Korean. I can’t judge the quality of the translations, so it’s recommended to try the demo…
- Secondary Melee Combat System - 25 September 2025
Hi All!I know many of you felt that randomness plays too big a role in the combat system. After the summer break, I began working on an alternative approach that eliminates RNG from melee combat.With this update, the game now includes a secondary melee combat system. You can enable it from the Options menu or select it when starting a new game. Ranged combat and magic are unaffected.Secondary melee combat system:Every attack hits but does not trigger a counter-attack. Dodge and parry skills can reduce the damage taken by up to 90%. If the attack is unseen, it always deals maximum damage. For human characters, the higher value between dodge and parry is considered. The passive ability called 'Protector' is more valuable since it triggers on every enemy attack.I hope the secondary combat system improves the gameplay experience. Please share your thoughts on how you like it. Starting a new…
- Bug fixes and UI improvements - 20 June 2025
Hi everybody,This update contains bug fixes, improvements to the user interface, and more tooltips about weapon and armor bonuses.Bugs fixed:Casting Dispel Magic can cause freeze.Casting the Invoke Fear spell on human characters caused the game to freeze.Insectoid opponents with Tail Strike ability were generated with short tails.Monsters can inherit Fly ability without having wings.The action point bonus on the character panel wasn't indicated correctly.The Quality settings dropdown button was occasionally irresponsive in the Options Menu.Missing tentacles from the Frogbeast's back.The "Attack bonus against hybrids" stat was mislabeled on the "Monster grew up" message.The ability button for Flawless Defense doesn't update after clicking on it, and the tooltip doesn't show the full description.Wrong instructions for the Skill Upgrade button in the tutorial.The auto-combat report incorre…
- Update 1.03 - 21 May 2025
Hi Everybody, RNG has been reworked The game used Unity's built-in Random.Range() function, which sometimes generated annoying values. I have also experienced cases where the archer missed twice in a row, even though the hit chance was over 90%. It truly feels unfair, but this is how random works. I checked how other games handle this and found they use manipulated RNG, where extremes are cut off. So, I have modified the RNG — it is no longer truly random, but it is less likely to produce extreme results in a row. I spent a lot of time testing it, and it looks better. I am interested in any feedback. How does the new RNG work for you? Encyclopedia The encyclopedia is back. I have updated it with the new content and features of the full-release game. Changes The arena battle does not provide chances for victory. Based on the result of the auto-battle, the player can decide whether to acc…
- Quick Patch & Combat Balance - 9 May 2025
Hi, Combat balance: Several of you have reported that combat feels more difficult in the full-release game compared to the early-access version. I made some changes. Enemies between levels 1 and 10 can no longer have more than one elemental bite or resistance, including poison bite and poison resistance. Additionally, Spiny Skin can no longer occur with Poison Skin, Shock Skin, or Fire Skin. Bugs fixed: The number of items in inventory was miscalculated. Weapons and armor equipped by characters were added to the inventory. I corrected the code to fix the mysterious "Phantom Enemy" bug. Since this bug never happened in the editor, I can't say with 100% certainty that it's fixed. We'll see. Spider Worm uses Energy Leach ability after death.
- Quick Patch - 7 May 2025
Hi everybody, I've put back the localization for German, French, and Simplified Chinese. It was done with DeepL without proofreading. I'm not sure about the quality. Unfortunately, the game's text exceeds 215,000 characters, equivalent to a 100–150-page book. Professional translation is currently not feasible. Bugs fixed: The arena fight description window does not contain the participant count for hybrids. Enemy hybrids without spiny skin get Total Spininess ability in the arena. Juvenile hybrids are occasionally generated without eyes when crossbreeding insects and mammals. The slave warriors are showing "Training skill" stats. Generate enemy hybrids without legs for arena combat.
- Full Release - 6 May 2025
Hi everybody, After three years, the time has finally come for the full release. Thank you for your patience and the many great ideas you've supported me with. Of course, development will continue—I have quite a long list of ideas and content that can still fit into this game. Here's a brief summary of what changes compared to Early Access. Graphic overhaul The 3D graphics and 99% of the user interface have been replaced. The armor and weapon 3D models remained but received new textures. This is a one-person project with a minimal budget, though for some essential tasks, such as animations, I hired contractors. Hybrid class While in early access only creatures belonging to the same class could be crossbred, now it is possible to crossbreed any creatures without limitations. The learnable abilities from each class are also accessible to hybrids if any of their ancestors belonged to that…
- Full release on May 6, 2025 - 21 April 2025
Hi everyone, Finally, I can tell you the exact date of the full release. The Monster Breeder 1.0 will be released on May 6, 2025. New content: Graphic overhaul Hybrid class Expeditions New species Reworked crafting (now includes shield, bow, and staff making) New abilities for monsters New character bonuses
- Full Release Playtest - 12 April 2025
Hey everyone, The full-release playtest is still running, and I’ve got a few keys to hand out! If you’d like to join, hop into Discord and post a message in the #full-release-playtest channel. Update: Sorry, but I handed out all the remaining keys. https://discord.gg/vam9GfcPBD The full release is planned for the first half of May — the exact date is coming soon!
- Development Progress - 9 January 2025
Hi All, I'd like to share a couple of screenshots from the full-release version. With the current progress, the February playtest still feels achievable. I appreciate your patience.
- Crafting Reworked - 14 December 2024
Hi All, I've reworked the weapon and armor forging system and introduced a few new features. These updates will be available in the Full Release. Skill Development Alchemists and blacksmiths no longer develop special skills randomly. Instead, they earn skill points upon reaching levels 10, 20, 30, and beyond. Players can use these points to select a special skill, such as 'Skilled Herbalist' or 'Enchanter,' or to remove a negative trait. This system allows for greater customization of craftsmen, making their development less dependent on chance. Bows & Shields The creation of bows, shields, and magic staves will now be possible. To craft these items, the blacksmith must possess a special skill called 'Master Smith.' Different types of shields will offer unique bonuses. For instance, the Cavalry Shield provides a +15% chance to block but offers less protection against arrows due to its s…
- Expeditions - 16 October 2024
Hi, I want to give a quick update on the progress of the development. One of the new content of the full release will be the expeditions. Three expeditions will be available in the game, northern, tropical, and islands. About a third of all species will not be available for purchase. These rare species live in remote areas and possess the most valuable features such as regeneration, flying, or ice breath. The player can launch expeditions to explore caves and get these rare and invaluable creatures. To do so, have to cover the costs and undertake combat against unknown opponents. Outlaws and rogue lords are ruling those distant lands and you have to fight your way through them.
- Development Progress - 30 September 2024
Hi, I would like to give you a quick update on the development progress of the past months. In the last couple of months, I worked on the new UI assets, and interiors, and integrated all the creature assets into the game. Unfortunately, I had to take a part-time job in August. As a consequence, I can no longer work full-time on this game, but the development will continue. I want to launch the full-release version before the winter sale. These screenshots represent the full-release version:
- Hybrid Class Inheritance - 23 June 2024
Hi, Finally, the inheritance algorithm is complete for all classes, including the hybrids. This short video shows how it will work in the Full Release version. Offspring appearance is generated based on parents' characteristics. In the next couple of months, I will focus on implementing the new graphical assets into the game.
- Insectoid Class Inheritance - 27 May 2024
Hi All, The inheritance algorithm of the insectoids is complete. This short video shows how the inheritance of external characteristics will work in the full-release game. I need some time to polish the hybrid inheritance algorithm, but the next video will focus on the hybrids of reptiles, mammals, and insectoids.
- Full Release Hybrid Creatures - 5 May 2024
Hi Folks, Finally, the 3D models of the Hybrid Class for the full release are complete! This short video shows some examples of hybrid creatures. The next step is creating an inheritance algorithm and testing it. There are still many things to do: arenas, user interface, visual and sound effects and not to mention implementing all these new assets to the game. I also plan to improve the crafting system and add quests. Luckily, the hardest part of the work is done.
- Inheritance of Characteristics for Mammals - 14 March 2024
Hi All, I am busy working on the new hybrid monsters for the full release. Fortunately, the inheritance algorithm for the Mammal Class creatures is complete, so I can show how the inheritance of external characteristics works. Hopefully, I will be able to post about the hybrids next time.
- Full Release Insectoid Species - 6 February 2024
Hi Folks, I have completed the new insectoid assets for the full release. This short video shows ten species and their strengths and weaknesses. Now, all three monster classes are reworked, and finally, I can start creating the new hybrid class. This will be a very exciting and challenging task!
