Nuclear Frost is an action-adventure first-person shooter where you have to face the threats that the new world has brought to the table. Fight mutants, keep yourself warm, avoid radiation and fight fungus to save your home.

Long ago, the world was destroyed by a nuclear war that wiped out the Earth's population and turned its surface into an icy wasteland. Only a handful of survivors took refuge in the bowels of the bunker, and human civilization was on the verge of extinction due to the Frozen Orusfaira fungus that was born.

This fungus spreads very quickly and is characterized by the fact that it transfers part of the DNA of the infected to a new carrier in spores. This leads to various mutations of sick people, such as bleeding trees with flesh, dogs with human hands, and so on.

Our hero did not find the war itself, he was born already in the bunker and only from the stories he knew what world was "Before". All the time his housing was subjected to outbreaks of the Ice Orusfairy epidemic, which managed to be eliminated .. but not now. The situation escalated to such an extent that almost the majority of the population was infected, including the hero. The moment has come to act decisively, so the hero is tasked with saving his home at any cost, even if he has to give his life for it.
