Killzone: Mercenary is a first-person shooter in the Killzone series, developed specifically for the PlayStation Vita platform and powered by the stunning Killzone engine. Starting just after the ending of the original Killzone, and revisiting many of the events from the Killzone trilogy, the game puts players in the rugged combat boots of a mercenary named Arran Danner. Danner is a former UCA-soldier who has no qualms about taking on paid contracts from the ISA as well as the Helghast.
Killzone: Mercenary makes full use of PlayStation Vita’s considerable input and graphics capabilities. It enhances the familiar dual-stick FPS control scheme with touch controls for actions such as brutal melee, and with tilt controls for accurate sniper aiming.
