It is 1999, shortly after the NATO bombing of Belgrade. A woman and her husband go camping in the countryside nearby—a brief escape into trees and fresh air. She wakes up and her husband is gone. Searching for him, she encounters something the bombing may have exposed or created: a creature called Siren Head, its upper body replaced by sirens broadcasting sounds that are not natural. She has to fight it. Whether Siren Head is a military experiment or something else is a question the game leaves partly open.
