After the doomsday catastrophe, the earth became a radioactive wasteland. A genetically modified soldier who awakened from a glacier laboratory unexpectedly inherited control of the "Frozen Throne", the ultimate war weapon left over from the old era. When he stepped out of the laboratory in a mecha that could freeze everything, what awaited him was a scorched earth full of mutated creatures, survivor warlords competing for resources, and a crazy AI hiding deep underground trying to restart the annihilation process. This is the story of the rise of a new king in the wasteland.
