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. 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.
