** [[https://metrovideogame.fandom.com/wiki/Homo_Homini_Lupus_Est Homo Homini Lupus Est]] achievement in the Faction DLC pack requires you to kill 100 enemies ''in one sitting''. It is difficult to achieve as it requires human precision to kill all enemies in the centre platform (running enemies on the right side do not count) so you also have to deal with your fellow soldiers taking for the kill as well.

* ThatOneAchievement: [[http://metrovideogame.wikia.com/wiki/Shadow_Ranger Shadow Ranger]] achievement. Its description says "''Complete the game without killing any Humans unless forced to''", which is pretty vague. As it turns out, the player is only allowed to kill during Chase, Red Square and D6 levels (however it's still possible, albeit very hard, to knock enemies out in [[GoodOldFisticuffs hand-to-hand]]), where the stealth option simply doesn't exist, while killing any human anywhere else fails an achievement and reloading a save does not fix that. The player has to start over with New Game. If you're particularly masochistic, try going for Shadow Ranger on Ranger Hardcore. Notably, ''Redux'' removes it and replaces it with several achievements for not killing on certain levels.

* MagnificentBastard: [[ChummyCommies Pavel Morozov]] is a cunning yet [[AffablyEvil affable]] soldier of the [[DirtyCommunist Red Line]] who manages to escape from a Nazi concentration camp while taking Artyom Chyornyj with him where they bond throughout their journey. With Pavel's friendship with Artyom only surpassed by his [[UndyingLoyalty loyalties]] to the Red Line, Pavel drugs Artyom and takes him to his superior, Czeslav Korbut, to be interrogated before being sent to Venice. Getting captured in Venice, Pavel is able to escape from his imprisonment before meeting with Korbut, where Pavel is assigned to unleash a [[TheVirus bioweapon]] into the D6 bunker to weaken its defense line for Korbut's invasion, while ambushing Artyom upon seeing him.

* AuthorsSavingThrow: ''Redux'' removed Shadow Ranger in favor of several achievements for not killing people on certain levels. Shadow Ranger is awarded for not killing any human enemies throughout the game, except where it is unavoidable (such as the end siege of D6, the train fight). However the achievement was incredibly bugged and the game didn't necessarily make it clear what constituted an "unavoidable" situation, leading to situations where players went through the entire game having killed no human enemies outside of scripted sequences and the achievement would not unlock.

* CompleteMonster: [[DragonInChief General Czeslav Korbut]] is [[TheChessmaster the brains]] behind the [[DirtyCommunists Red Line]], a neo-Stalinist army that aims to conquer the Metro. [[ManipulativeBastard Manipulating]] his superior Maxim Moskvin into poisoning the latter's own brother and political rival Andrey, Korbut exerts more control over the Red Line than their leader by {{blackmail}}ing him with this information. A genocidal megalomaniac, Korbut tests a bioweapon by deploying it against the peaceful station of Oktyabrskaya before attacking D6 to eliminate the Rangers and obtain more samples of the deadly virus, seeking to repeat the destruction of Oktyabrskaya with the entire Metro just to rule over what remains.

* UncannyValley: The facial animations of the human characters are rather well-done (complete with intricate eyebrow expressions). Unfortunately, the hair (all hair, in fact, be it the scalp or the beards) looks like it's sculpted out of plasticine which makes things... weird.
