After a global acid rain of unknown radiation,
Half of the world's flora and fauna mutated, giving birth to mutant beasts and plants with different personalities.
There are only tens of millions of people left scattered around the world, and some humans have awakened their natural powers.
The apocalyptic order slowly collapses, and human survivor bases, scattered teams and lone survivors appear.
The villains are mainly human beings competing for resources, and good and evil coexist in human nature.
The settings of mutant creatures tend to be cute, silly, and cute in contrast. There are very few bloody and scary scenes. Some mutant beasts even have comedic attributes, which can be teased and harvested to weaken the cruelty of the apocalypse.
Radiation rain has not disappeared and will appear from time to time.
