It is the year 2034‎.‎ Beneath the ruins of post‎-apocalyptic Moscow‎,‎ in the tunnels of the Metro‎,‎ the remnants of mankind are besieged by deadly threats from outside – and within‎.‎

Mutants stalk the catacombs beneath the desolate surface‎,‎ and hunt amidst the poisoned skies above‎.‎ But rather than stand united‎,‎ the station‎-cities of the Metro are locked in a struggle for the ultimate power‎,‎ a doomsday device from the military vaults of D6‎.‎ A civil war is stirring that could wipe humanity from the face of the earth forever‎.‎ As Artyom‎,‎ burdened by guilt but driven by hope‎,‎ you hold the key to our survival – the last light in our darkest hour‎.‎‎.‎‎.‎
