Eternal Voyage

Eternal Voyage is a secret achievement in Metro Exodus that can be obtained at the end of the game.

Overview
This achievement is obtained at the end of the game if the player got a "bad" ending, which is triggered if they got a "bad" ending for two or three of the listed chapters: The Volga, The Caspian, and The Taiga. If they don't obtain enough moral points for two of these chapters, the "bad" ending is triggered.

If the player accumulates enough moral points and receives the good ending, a more valuable achievement - Your Destination - is awarded instead.
