Oleg

Oleg Antonovich (Russian: Олег Антонович), or Olezhenka, is a resident of the Moscow Metro, the young child of Anton and resident of Kievskaya. Oleg is very inquisitive of everything that he comes across and befriends Artyom almost immediately. Miller gives him several cartridges, similar to the ones Hunter gave to Artyom, and Oleg uses them as toy soldiers.

Kievskaya station was suffering from mysterious events, with many of its station residents disappearing, most notably the children. Oleg unfortunately becomes one of the children to disappear. Artyom and Oleg's father, Anton, go in search of Oleg before discovering the Savage Cannibals of the Great Worm Cult, hidden in Park Pobedy.

After rescuing Oleg, Artyom, Miller, an injured Anton, and some heavily equipped Stalkers enter Metro 2. The Biomass corners the group on top of a train car, and slowly hypnotises each of the members. An unnamed stalker and Oleg, in a hypnotised state, jump into the creature and are killed instantly. As soon as Oleg dies, Anton fully awakens to find that his son has succumbed to the monster.
