Metro Exodus
While in Novosibirsk, Miller discovers that Lake Baikal and the area around it is clean, thus finally finding a permanent refuge for the Aurora crew. In both endings, the crew arrive to Lake Baikal after Artyom retrieves the drug to cure Anna. In the "Your Destination" ending, Miller is buried overlooking the lake, while Artyom, Anna, and the rest of the crew pay him respects. Command of the Order is officially passed to Artyom, who vows to uphold the Order's mission of helping people, hinting that he wishes to bring other survivors to Lake Baikal. In the "Eternal Voyage" ending, Artyom is buried alongside Miller and given a military funeral. Anna vows to continue living at the lake, out of love for Artyom.
