Many people around him are aware that he is right, but they are part of the conspiracy that tries to hide the existence of outside world.

Cassandra Truth: In 2035 and Exodus nobody believes his claims that there is life outside the metro and most people instead believe that he has gone completely insane.

The Metro 2035 book consists mostly of Artyom getting beaten, shot, irradiated, betrayed and laughed at until he is near to becoming insane.Butt-Monkey: Suffers quite a bit of abuse in the games, being captured several times (often involving his face quickly getting acquainted with someone's rifle stock), attacked by mutants, falling or getting knocked off railcarts, and having platforms/stairs giving way beneath him.Yet Artyom is lucky enough that, afterwards, things always happen at just the right time to save him and get him out of the jam. He is unlucky enough that things tend to happen at just the wrong time (someone looks his way when sneaking, a floorboard give away, etc.), putting him in life endangering situations.

To list, he has been: Knocked off a trolley and forced to run from mutants (rescued by Riga station guards), spotted sneaking into a bandit camp and is almost shot by their leader (rescue by Bourbon), captured by Nazis (rescued by the Rangers: Ulman and Pavel), almost falls off the Ostankino Tower (rescued by Miller), captured by Nazis again (rescued by a Communist soldier named Pavel), captured by Communists (rescued by the Communist Leader's son), on the verge of having to blow himself up (rescued by the Dark Ones), near fatally irradiated and dogpiled by mutants (rescued by a Ranger team), captured by cannibals and almost butchered for food (rescued by Sam and Idiot), falls into a river and almost drowns (rescued by Olga), gets the hell knocked out of him by a Blind One and falls several floors into an irradiated hellhole (rescued by Miller), due to exposure to said irradiated hellhole he gets lethally irradiated again (possibly rescued by the crew of the Aurora depending on the ending). He gets captured or imperiled so often that its surprising he isn't considered The Load by everyone.

Badass in Distress: Constantly, though always by Cutscene Incompetence.

The Atoner: In Last Light, after most of the Dark Ones are killed.

In the game, though many of these weaknesses still apply to Artyom, he's a One-Man Army from the get go, who is able to mow down hundreds of men and mutants on his own, though he still gets his ass kicked a few times.

Adaptational Badass: In the Metro 2033 book, Artyom is an Action Survivor who has almost no fighting experience when leaving the VDNKh station ( Exhibition in the games) and is only able to survive because he's a good shot, is relatively unaffected by psychic phenomena, has much more experienced companions helping him along the way and The Dark Ones are watching over him.

Since he can receive any type of blood, all of his fellow Rangers donate their own blood to him to replace his irradiated blood.

AB Negative: Artyom's blood type is mentioned to be AB Positive in Exodus, which becomes critical later when he suffers lethal radiation poisoning.

In the good ending, he is even promoted to the rank of Commander and chosen as the de facto commanding officer of the entire order. While neither he nor Anna are 'formally' reenlisted into the Order, no one treats him any differently than as if he had never left and he even follows Miller's orders like before. This doesn't stick as fate isn't done with him and he finds himself back with the Rangers by the end of the first chapter of Exodus.

10-Minute Retirement: Between Last Light and Exodus he, along with Anna, resigns from the Rangers and moves back to Exhibition to search the radiowaves for outside survivors.

He is soon called to adventure, however, to warn the rest of the Metro of the mysterious Dark Ones. The Player Character of Metro 2033, Last Light and Exodus, Artyom has lived most of his life in the underground Metro tunnels.
