The world of Metro Exodus is full of dangers, hostile factions, and deadly monsters. To survive in this world, you will have to make difficult choices impacting lives of others. This chapter in our guide to Metro Exodus focuses on the morality system and choices.
How do the morality system and choices work in Metro Exodus?
Let's start with the fact that every large location (the Volga, the Caspian Sea and Taiga) has its own morality system. There, you will have to make moral choices that are usually about killing/stunning enemies. Depending on the decision you make, you will have a different ending for a given chapter - stunning enemies and completing side quests will give you a good ending where e.g. one of your comrades survives.
Also, the game's ending depends on how many companions have survived until the end. Some of the dialogs or cut-scenes are also affected by e.g. death of a specific character. Your friends can also celebrate the fact that everyone has survived.
Some of the enemies can surrender during a fight - killing them leads to the "bad" ending, stunning them will get you closer to the "good" ending.
In conclusion: Moral choices affect your allies, leading to different endings.
