Metro 2034

The year is 2034. There's no hope for humans to return to the surface of Earth, to repopulate the forsaken cities, and to become once again the masters of the world they used to be. So they rebuild a strange and grotesque civilization in the tunnels and at the stations of the subway. Stations become city-states that wage trade and war on each other. A fragile equilibrium is established. And then all can be ruined in matter of days. A new horrible threat looms that can eradicate the remains of humanity and end our era. It would take three unlikely heroes to face this menace.
