In 2077 AD, the "extraterrestrial crystal tide" raided the earth. Unknown crystals brought by meteorites infected the world. 70% Of humans mutated into bloodthirsty "crystal beasts". Cities fell and civilization collapsed. What's even more frightening is that the radiation released by the crystals transforms the environment, spawns various strange resources, and awakens "superpowers" in a few humans. However, most survivors can only struggle to survive in the ruins, and the law of the jungle becomes the law of the jungle.
It's not easy.
