Description of the world of Styx from Artem Kamenisty. The idea of the “Styx” series originated during the development of a computer game. There is practically no gaming component left in it, although some elements are similar to elements of the LitRpg genre (something like leveling up heroes, developing skills, obtaining loot). In this form, the series, albeit with a stretch in places, can be classified as a survival horror genre (classic and unorthodox representatives of the genre, in games: The Last of Us, Rust, DayZ; in films and TV series: almost everything in the spirit of director Romero, that is, “28 days later”, “I am a legend”; in the books: “Feed”, “The Fifth Wave”).
