Execute contracts carefully, creatively, or chaotically and receive a rating after the mission, from apprentice marksman to expert marksman - and, of course, the coveted silent assassin.
As you conquer each mission, you will complete challenges and earn XP that will grant you new outfits, weapons, items, and gadgets that will give you an advantage when repeating missions. Gain a tactical advantage by starting a mission from a new vantage point or have your Agency hide items for you.
