End of the world, or a new beginning? In the middle of the 21st century, a series of catastrophic events led to the death of civilization. It all started with a natural anomaly. The sky over the entire was enveloped by fiery red clouds that burst into flames. And then it was black. The sunlight faded, unable to break through the thick haze that followed. "The eternal night" enveloped the world. Day was dusk, and the nights were incredibly dark and full of fear and chaos. Over time, things got even worse. Those who were in a panic roamed the streets of the night city, and mutations on their bodies began to create terrible deformities. They merged with various objects, animals, and even each other. In an effort to curb the threat, the armed forces of various countries began to launch pinpoint nuclear strike on the largest clusters of mutants in the megacities. Some of monsters were killed, but the radiation has created a new wave of mutations, even more powerful and terrible. Cold, ruins, storm rainfall, mutants and radiation abound in this new world, a world without light.
