Publisher : Sony Computer Entertainment
Release date : February 2011
The game picks up immediately after the ending of Killzone 2 and follows the previous games' main protagonist, Sev, a Special Forces operative fighting for the Interplanetary Strategic Alliance against the Helghast Empire. The game continues shortly after Sev successfully defeated Radec and Rico having killed Visari, the Helghast dictator who leaves them to a fleet of Helghast ships approaching them destroying ISA vessels.
The death of their dictator has left the Helghast Empire in a state of internal struggle. Now, Sev and his comrade Rico are trapped in the cross-fire between the various political factions without any reinforcements and are left to fight alone in order to escape as the ISA struggles to regroup its forces and stop a Helghast invasion of Earth. The game will also give players a deeper look into Helghan culture such as their language and showcase whatever humanity they have left within them.
Killzone 3's story will also be more light-hearted compared to its predecessor, which Guerrilla felt suffered from an overly serious and dark story which was one of the major complaints of the original, though they mentioned that it would not be too light-hearted as it is still a war. In addition, Guerrilla Games has hired an external writer to focus on only writing the storyline so as to give a fresh perspective to the story as well as hiring a lot more Hollywood actors to elevate the level of storytelling within the dialogue of the game.
Guerrilla Games has also mentioned that the game's story will be an integral part of the game with dialogue and character development being greatly improved from its predecessor. In addition, Guerrilla Games has also said that they are curtailing the swearing in Killzone 3, which many felt was unnecessary in the dialogue of Killzone 2. They mentioned that the dialogue in the game should be focused on advancing the story rather than "gratuitous" swearing.
The Killzone 3 "Justice Trailer" reveals new characters: the resourceful female ISA member Jammer, as well as the hopeful heirs to Visari's throne, Jorhan Stahl (played by Malcolm MacDowell) and Admiral Orlock (played by Ray Winstone).
