Dear readers! Perhaps some of you have already read our “Switch” - a story about the world of the computer game STALKER. We honestly tried to write a sequel, but in the end we ended up with a parallel thread of events. Therefore, do not be surprised if you come across characters and events that are already familiar to you in the text. “Polygon” begins with the adventures of new characters - Hedgehog, Kashchei and Caretaker, who will then meet Roman and Ben and go through a joint quest. Welcome to the Exclusion Zone!
