The year was 2100 AD, and the aftermath of the devastating global nuclear war, known as World War 3, had engulfed the world. This unexpected war had ended quickly with the destruction of major cities around the world. After the nuclear war, one third of the population had been wiped out. The nuclear storm scorched the earth, rendering it barren and unforgiving. The air had filled with toxic radiation, and the very essence of life had been polluted by its presence.

Those who had managed to escape the initial devastation found themselves thrust into a harsh new reality. Survivors had been physically and emotionally scarred, clinging to fragments of a world they once knew. They had to scour the ruins of their once-great cities, searching for meager resources to sustain their fragile existence. But survival comes at a cost. From clean water to edible food, limited resources are fiercely contested. Amidst this ruthless struggle, a new threat emerged from the shadows. There were not even the worst. Most of nuclear survivors had not realized what they were going to face: the ensuing nuclear winter had pushed humanity to the edge of extinction.

Two years after the WW3, the world finally had seen the end of the nuclear winter. Survivors emerged from their shelters, but their lives had changed forever by the disaster that befell them. The world of 2100 was once a prosperous, vibrant place—a testament to human intelligent and creativities. But now, all that remains in front of them are crumbling ruins, the skeletons of skyscrapers. Nature itself has fallen victim to human's self-destructive wrath, with once lush landscapes now desolate and barren.
