Intro. Hello, survivor. The world is dead. The surface is a radioactive graveyard, mutated beasts and packs of bandits. But underground, in the tunnels of the Moscow metro, man survived. We believed it for years, until he – Colonel Miller, commander of the Order of Spartan – discovered something that changed everything: life is outside of Moscow. We set off on a journey on the Aurora train to find a new home. You? You are a new acquisition, found somewhere along the trail, ready to join our journey through ruined Russia. Get ready, it's going to be a long, dangerous road...
