After a nuclear explosion, the lives of those who managed to survive were turned upside down. We had to adapt to new conditions and this did not suit everyone. The hero of the game Nuclear Day was left alone, his family died, he sat in the basement for a long time and finally decided to come to the surface. We've run out of food and water, which means we need to act. There is an endless redistribution of territories in the city, gangster groups are rampaging and you need to be constantly on your guard. So as not to meet with the patrol. Help the hero find new shelter, food and drink, and possibly weapons, because you need to somehow defend yourself in Nuclear Day.
