Despite originally releasing over a decade ago,Metro 2033still holds up as an iconic action-shooter and represents, for many, the pinnacle of the series.Metro 2033 Reduxis a graphical remaster with a few technical improvements, but the overall gameplay and story remain unchanged. What many players may not realize is thatMetro 2033actually has multiple endings, though they are cleverly disguised so that it isn’t obvious when you are making adecision that will affect the story’s outcome.

Throughout the game, Artyom is continually being judged based on a Moral Points system. There may be chances to pacify enemies non-lethally, help out neutral NPCs, or complete mini side-quests in order to improve Artyom’s standing. Similarly, Moral Points can be lost by making bad decisions and killing too many enemies where it is not necessary. While it is not clear exactly how many Moral Points arerequired to generate the ‘good’ ending, it seems that at least a 50/50 balance between good and bad deeds is required — though the more good, the better!

The completion of good deeds will result in a brief white flash of the screen and the echo of a water-dripping sound; however, there is no explicit indication when a bad act has been committed. Though it may not seem possible at first, players can actually earn a special achievement forcompleting the entire game without harming a human enemy. Here is a breakdown of every way in which Artyom can gain (or lose) Moral Points through each mission of the game:
