Major update

Easter eggs and new game mechanics

Hi,

This update adds a couple of new mechanics. These new features affect primarily the monster breeding part of the game, adding more challenges and complexity.

Easter eggs

I added four hidden abilities to the game. These abilities may appear in offspring if the parents belong to certain species.

Crippling mechanism and damage capacity

All the monsters have a new inheritable trait called damage capacity. This indicated the amount of HP losses they can accumulate without the risk of becoming cripple. Whenever monsters lose HP in combat, the damage capacity decreases. When it is exhausted, the chance of getting a crippling wound increases, and being defeated means the end of a career. Crippled creatures can no longer participate in any fight but still can reproduce.

Combat injuries

Monsters can get injured or seriously injured when defeated in non-lethal combat. The chance of injury is higher for creatures with the "Fragile bones" trait.

Crossbreed potion's strength

The potion strength of the Crossbreed Potion will have a significant effect. Weak potions cause random harmful traits in the offspring.

Harmful traits

  • Light Hemophilia - Loses 2 HP for 2 turns after being hit
  • Hemophilia - Loses 4 HP for 3 turns after being hit, and blood draw or organ implantation is not possible
  • Severe Hemophilia - Loses 6 HP for 4 turns after being hit, and blood draw or organ implantation is not possible
  • Fast aging - Becoming old at 50% of lifespan
  • Untamable - Not possible to tame this creature
  • Fragile bones - Can be crippled when defeated in combat, regardless of the damage capacity
  • Sickliness - Moderate illness is fatal, and organ implantation is not possible
  • Fast metabolism - The upkeep cost is double due to increased food intake
  • Single offspring - The litter size is 1

Effect of hemophilia in combat

Melee weapons, bow, bite, claw, or spiny skin cause physical damage and trigger bleeding if the monster has hemophilia.
Elemental and poison damages like magic staff, Ice Breath, Poison Spit, or Shock Skin do not cause bleeding wounds.

Inbreeding

All offspring of closely related creatures get inheritable harmful traits and a not-inheritable trait called Inbred. If a parent is inbred, the offspring may get harmful traits but not inherit the Inbred trait.

The aging algorithm has been modified, and now you can see the number of turns until growing old.

Auto-combat has been reworked. The losses better reflect the combat power of each team.

Bugs fixed:

  • Shady Business quest starts all over again after the completion
  • Pop-up info of strength can be stuck at the "Monsters" window

In-game event28 Apr 2026Manipulating the appearance of offspringHi 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 inh…In-game event6 Feb 2026User Interface UpdateHi 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 few…In-game event21 Nov 2025Language & Engine UpdateHi, 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:…
