October 2026. A new crisis is brewing in the Zone. Through a space portal, an army of unknown creatures has entered its territory—creatures that destroy everything in their path. A task force called “Dolzh” tries to resist, but is defeated, because the invasion is led by the legendary Shooter. To survive the slaughter, all surviving stalkers must unite. The situation quickly gets out of control, and the command of the international forces prepares to launch a secret global cleanup program. The fate of the Zone is now in the hands of a veteran stalker known as Plumbum and a mysterious creature calling itself Charon.
