Killzone: Liberation, two months after the events of "Killzone," (PS2) most of southern Vekta is still under Helghast control. The rules of war have been cast aside with the Helghast General, Metrac, employing brutal measures in order to seize the initiative and strengthen his position further. Returning as Templar, players will be sent on a mission to undertake a covert operation to save hostages captured by Metrac, while ISA troops continue the fight for liberty. Featuring an intelligent third person camera system, Killzone: Liberation allows players a more tactical surveillance viewpoint to view their action and read the enemy’s behavior during gameplay.
