Killzone Mercenary: New Single-Player & Multiplayer Details You are Arran Danner, a mercenary currently under contract to the ISA. Your mission is to infiltrate a battery of Arc cannons and direct their fire away from the ISA fleet, instead targeting the Helghast cruisers overhead and opening a way into the city. This is critical to enabling the invasion of Pyrrhus to begin in earnest.
