A year after the events of Metro 2033 the last few survivors of the apocalypse, surrounded by mutants and monsters face a terrifying new danger as they hang on for survival in the tunnels of the Moscow Metro.

World War Three wiped out the humankind. The planet is empty now. Huge cities became dust and ashes. Railroads are being eaten by rust. Abandoned satellites hang lonely on the orbit. Radio is mute on all the frequencies. The only survivors of the last war were those who made it into the gates of the Metro, the subway system of Moscow city. It's there, hundreds of feet below the ground, in the vaults of what was constructed as the world's largest air-raids shelter that people try to outlive the end of the days.
