Muskeg is the new Legendary shotgun BP in COD Warzone. Getting or Unlocking it means doing a set of objectives. But before starting to do these objectives you need to activate the Mission within Call of Duty MW itself. In order to do that, head over to Barracks > Missions & Challenges > Warzone Missions and select the mission given below. Take note that your previous mission activation will be replaced by this one, so decide wisely.
