The game is set in a near future, thirty years after the events of Killzone 3. The world is a very different place; two rival factions known as the Helghast and the Vektans live side by side in a futuristic city, divided by a vast wall. Tensions are high, and the cold war they are embroiled in is about to go hot. In the midst of this all stands a Shadow Marshal, you. The most special of the special forces, tasked with maintaining the delicate balance. From responding to bold attacks, to quiet infiltrations or all out combat, you will be required to adapt and think on your feet as you have to face a variety of escalating events that could destroy your home world.
