S.T.A.L.K.E.R.: Shadow of Chernobyl was released in 2007 by Ukrainian studio GSC Game World, and its story follows a stalker exploring the forbidden Exclusion Zone around Chernobyl. The main theme became closely tied to that lonely, dangerous world, and fans have kept sharing it in gameplay videos, edits and streams long after release. Its slow, ominous sound still works as instant shorthand for the Zone, which is why new players discover it through sequels, mods and retrospective videos today.
