Operators have become license -specific for many years and allow players to experience the Call of Duty experience in another way, bringing some variations in gameplay, albeit minimal. Each of the Operators comes from a different region, also offering insight and customization that stands out from the rest, making them coveted.
However, not all of these operators are accessible from the start of the multiplayer adventure in Call of Duty: Modern Warfare 2. You will have to play and complete some challenges. So, if you want to know what actions to take to get your hands on this or that character, we explain how to do it.
