Set somewhere in the eastern bloc in the late 1980s where a mysterious forest has occupied a large amount of land and is continuing to expand, many people have been left trapped by the forest and a strange plague is ravaging the survivors, killing and causing victims to transform into monsters and abominations. A group named "The Outsiders" consisting mostly of government officials and soldiers was sent to investigate the woods, setting up the hideouts and a tunnel system to get in and out of the forest.
