3,000 years ago, there was a chain of underground disasters that provoked global volcanic eruptions, after which life on the planet became impossible.

However, a tiny part of humanity has been able to adapt to extreme conditions, survive volcanic winters and learn to live in conditions of greenhouse heat and acid rain.
The settlements are located in isolated underground spaces built in the early years of the disaster in deep natural caves. Due to the toxic environment, surface access is limited and strictly protected. However, some of the structures built on the surface support life underground and require human observation.

Insects, reptiles and some underwater creatures have mutated, and people are forced to purify toxic water on an industrial scale, synthesize animal proteins and constantly fight hostile environments.
A three-stage system for the treatment of acidic precipitation for the provision of human-friendly fresh water.
Ventilation shafts and manholes leaking natural light reach the surface.
Because direct contact with the outside environment is deadly for humans, but research is necessary, multifunctional collecting robots are used to interact with mutated plants.
A drone in the assembly of a flying combine helps to collect and process mutired samples of adapted plants for the study and consumption of non-toxic fruit hidden under a poisonous shell.
It is not only by adapting and studying, but also by using physical force, that the battle against wildlife and the external threat takes place.
Work on the surface requires functional, light and small-scale weapons made of stainless volcanic alloys.
You need to be fully prepared before you leave the safe haven to the surface.
