Taking into consideration the narration of the sci-fi book “Roadside Picnic” by the Russian authors Arkady and Boris Strugatsky, published in 1972, various elements of the Zone are studied and analyzed. The “Zone” is located in the notional town of Harmont, an exclusive zone with constant patrols. According to the story, the "Visitation" took place, an event that changed the areas in which it happened forever. The inhabitants of the areas soon became ill, unpredictable and unexplained phenomena also took place. Residents then fled the areas, which were excluded from the public for security reasons. The Visitation is about the arrival of extraterrestrial organisms on earth and is compared in the book to a picnic, due to the fact that various remains / objects were left behind, whose function was initially unknown. “Stalkers”, as they are called, are individuals that trespass the walls of the Zone with the intent to loot it and collect these grotesque objects, regardless of the great risks, so they can later sell them to the black market. The most valuable object of the Zone, however, is said to be the key to happiness for anyone who manages to find it. A hunter must overcome the instability and uncertainty of the Zone in order to survive and collect the most important of all, the so-called Golden Sphere. Based on the aforementioned plot of the book, the aim of this thesis is to create interactive environments where the individual will be able to experience the post-apocalyptic world of the Zone, its unexpected phenomena and follow missions as a Stalker in hope to find several of Zona’s Artefacts with the ultimate goal being the finding of the Golden Sphere.
