The events of Killzone 2 are immediately followed by the beginning of this chapter in the story. The army of the Interstellar Security Alliance (ISA) launched an attack on Helghan, the homeworld of the Helghast, and managed to kill Emperor Visari in the process. The game will proceed from there, with the surviving troops in front of the Visari palace retreating toward the remainder of the fleet and leaving the planet once they have completed their mission. The player will play the part of Sergeant Tomas Sevchenko once more and will be accompanied by his friend and fellow soldier, Sergeant Ricardo Velasquez. As the soldiers, under Captain Jason Narville’s leadership, begin to pull back, they run across significant Helghast opposition. In the midst of everything, Rico disobeys a clear command and goes off on his own with Sev to rescue a group of soldiers trapped by the heavy fire of the enemy. Six months later, the ISA fleet arrived back on Earth, and the few soldiers who hadn’t made it there were either imprisoned or hidden away somewhere. In the meantime, the Helghast Senate selected Admiral Orlock as the new leader, which spurred Chairman Jorhan Stahl to step down and make the decision to take matters into his own hands by creating a new lethal weapon and ultimately attempting to eradicate the enemy’s home planet, Earth. Despite the overwhelming odds, Rico and Sev have decided to free all the prisoners and prevent the hostile fleet from reaching Earth.
The gameplay is noticeably more streamlined and well-balanced than its predecessor because of the numerous enhancements implemented. You will take control of various turrets and vehicles, similar to how you did in the last game. This will increase your firepower, but the gameplay will still be rails-driven. As part of the new exoskeleton, one of the new weapons is a jetpack that allows you to jump and semi-fly while providing a limitless supply of ammo. You can sometimes ruin the environment or use it to your advantage. For example, shooting barrels or specific plants will remove opposing soldiers. Killzone 3 features a single-player campaign and a multiplayer mode, an improved version of Killzone 2’s multiplayer. Additionally, it is the first game in the series to be compatible with 3D televisions.
