Killzone: Mercenary proides a new perspective on the Killzone Universe. You’re not simply an Army grunt folling orders - you’re freelance gun for hire, a merc - a soldier of fortune - someone who doesn't play by the rules or fight for any particular flag. They’re in it for the cheddar. The client might enumerate the objective, but he won't tell you how to do your job. You formulate your own tactics and choose your own weapons; so long as you get the job done.
