The Metro universe is born in the aftermath of nuclear war between Russia and an unknown number of other countries. In the nuclear exchange, the surface of Moscow has become heavily irradiated. The lethal radiation levels have produced horribly mutated creatures who roam the surface of Moscow. Seeking shelter from the nuclear wasteland, the surviving humans retreated into the Moscow Metro, where they have eked out a living for several years. But the tunnels of the Metro are home to even more dangerous mutants that threaten to exterminate the remnants of civilisation.
