GSC Game World is a Ukrainian game developer founded in 1995, best known for the Cossacks series and the STALKER first person shooters beginning with Shadow of Chernobyl in 2007. Its logo intro appeared before those games, becoming closely linked to the eerie, post apocalyptic atmosphere of the Chernobyl Exclusion Zone setting. As clips and memes from older PC games circulated on YouTube and soundboards, the intro was isolated as a standalone sting that fans recognise instantly, even without the logo animation playing alongside it.
