One of the rarest artifacts of the Inside Out. According to stalker tales, whoever manages to obtain the Rubik will always be lucky on their outings. Those who do not believe in the tale find a simple explanation for this “luck“—the Rubik boasts an exceptionally diverse range of useful properties, making it a good fit for numerous builds. Like some other Inside Out artifacts, it has no known direct parent artifact or analogue found anywhere in the regular Zone. However, many stalkers, fond of speculating on popular topics or pitching their genius ideas to scientists, claim that the Rubik might be some kind of hybrid of the Polyhedron and Atom.
