Siren Head Sound of Despair

It was just a few months after the bombarding in Belgrade. The Year was 1999. My husband and i went camping near the city. There is a nice piece of nature there. Trees, grass, fresh air… But then it happend! I woke up and my husband was gone! I must find him. Hope he’s not hurt. Hope is all i got now. Once i start to search for my man i encounter him… Siren Head is his name. Was this some kind of military secret project or some strange mutation? I have to fight it, have to kill it…
