Ariadna Device
Ariadna is a mysterious device resembling VR goggles, which is located in Igor's room. This device can recreate past events through a virtual simulation using clues and facts.
Throughout the campaign, the player uncovers photographs, emails, and diary entries, which Igor organizes on a board in his room. Once enough clues are gathered, Ariadna generates a VR simulation resembling the fractal world within Chernobylite, allowing Igor to delve into the conspiracy surrounding the state-sponsored Chernobylite experiments and NAR, as well as Tatyana Amelieva connection to both. While it doesn’t provide all the answers, it offers significant insight into the overarching plot.
The experience is fairly linear, with players walking through corridors while scenes unfold, narrated by Igor in his professor-like manner.
Simulations[]
To complete a board, you need to uncover all the facts. These facts are automatically revealed once you discover one or more clues. There's no need to collect all the clues to start a simulation.

Trivia[]
Igor mentions the legend of Ariadne and Theseus as inspiration for the prototype's name.
In Greek mythology, Ariadne is the daughter of Minos, king of Crete. When Theseus sets off for the Minotaur's Labyrinth, Ariadne gives him a sword and a thread of wool (Ariadne's Thread) so he can find his way out of the labyrinth.
