Humans originally wanted to use large-scale nuclear weapons to solve the problem of global warming, but accidentally caused the earth to deviate from its orbit, causing unprecedented severe cold, and the world began to enter the fifth ice age in history. To make matters worse, the nuclear explosion also unleashed an ancient Antarctic virus that gave life on Earth unprecedented tolerance to the cold, but also robbed them of consciousness, creating ruthless hunters of the freezing cold known as "ice ghosts." Welcome to be a survivor in the ice world, you are in such a post-apocalyptic place covered by frost, resource depleted and dangerous. Like the human ancestors 200,000 years ago, your only purpose is to continue the fire of humanity, and all you can do is explore and fight. Fortunately, you can find scarce survival resources under the ice, and you can even recruit survivor heroes to build your own safe zone, military facility or even a research institution. You will lead others to survive and develop in the final cold, recover the lost technology, and find the secret to reverse the ice field. As for the other camps of survivors, whether to unite with the newspaper group to keep warm, or follow the law of the jungle to prey on the weak, your values will determine the laws of human beings in the last days. Let me tell you the secret to surviving here: don't give up hope.
