Metro Exodus: From Moscow to Lake Baikal

The game opens in 2035, with a nuclear war behind it. Hansa soldiers shoot Artyom and take Anna hostage; after he frees her they escape by stealing a Hansa locomotive they later name the Aurora. The Spartans flee Moscow aboard it. The Moscow Metro they leave is real: it opened in 1935 with one 11-kilometre line and 13 stations.

Location precision: The pin marks Moscow; the story does not tie the escape to one station.

The Spartans cross the Volga, held by a technophobic cult, and pick up a passenger cart and a railcar on the way. Here Anna breathes poisonous gas, and it later makes her ill. The real Volga is the longest river in Europe. Anna's illness will shadow the Spartans for the rest of the trip.

Location precision: The game does not say where the crossing happens; the pin sits on the river in central Russia.

A radio call asks survivors to rally at the Ark, said to be at Mount Yamantau. Miller hopes the government has rebuilt there, but the crew have become cannibals who lure survivors with false promises of safety. The real Yamantau, in the Southern Urals, is 1,640 metres high, and its name means evil mountain in Bashkir. US claims allege a secret bunker beneath it.

Location precision: The game names Mount Yamantau for the Ark; the pin marks the real mountain, and the bunker under it is only alleged.

Using a map from Yamantau, the Spartans reach a satellite communications centre in the dried-out Caspian Sea, held by slavers. They help the local resistance fight them and leave with fuel and water. The real Caspian is the world's largest inland body of water, and the Volga flows into its shallow north end.

Location precision: The game's Caspian is a dry seabed; the pin marks the middle of the real sea.

Miller and Artyom go alone into irradiated Novosibirsk to find an antidote for Anna. In its metro they meet Kirill, the last survivor of the city. On the way back Miller gives up his own serum dose to save Artyom and dies of radiation poisoning. The real Novosibirsk Metro opened on 7 January 1986 and has two lines and 14 stations.

Location precision: The pin marks Novosibirsk; the game's metro levels are not tied to named stations.

With the map Miller recovered, the Spartans settle on the shores of Lake Baikal, which is free from radiation. In the good ending Artyom plans to return to Moscow and tell the people of the Metro the truth. Baikal is the deepest lake in the world and was named a World Heritage Site by UNESCO in 1996.

Location precision: The game gives no exact shore; the pin marks the lake's centre.
