"Killzone: Mercenary" gives a new perspective on the "Killzone" Universe. This time you’re not an Army grunt who follows orders - you’re freelancer, a gun for hire, a soldier of fortune.
These guys don’t play by the rules or fight for any flag. They’re in it for the money.
The client might give the objective, but they’re not going to be telling you how to do your job. You get to pick your own gear and tactics; as long as you get the results.
"Killzone: Mercenary" hosts a full single player Campaign, spread over 9 missions. In addition to the main missions, there is a new Contracts mode, offering an additional 27 sets of objectives.
You can choose from three difficulty settings; Recruit Trooper and Veteran. The harder the difficulty selected the higher the rewards gained.
