Visari, the leader of the Helghast is gone, but the war is far from over. Helghast forces have mounted a devastating counterattack, prompting the ISA (Interplanetary Strategic Alliance) to smoke out evacuation of planet Helghan. As new Helghast battalions appear, armed with more powerful weapons, ISA forces find themselves outmanned, outgunned and surrounded. Players of Killzone 3 will need to learn more about their enemy and use new tools to continue the fight.
The game begins in medias res from the point of view of (presumably) two Helghast soldiers who have arrived at Stahl Arms Corporation, Jorhan Stahl's weapons factory. The two are taken to an execution room where the captured Jason Narville's execution is about to be broadcasted by Stahl across Helghan. As the two soldiers are about to execute Narville, they reveal themselves as Tomas "Sev" Sevchenko and Rico Velasquez and the scene cuts back six months earlier, immediately following the events of Killzone 2.
