In Killzone®: Liberation, two months after Killzone® events, most of the South Vekta is still under Helghast control. The war rules have been abandoned by General Helghast, Metrac, using brutal measures to take advantage of the initiative and strengthen its continued position. Returning as Templars, players will be sent on a mission to undertake a secret operation to save the patterns captured by Metrac, while the ISA troops continue for freedom.
