Immunity has heard desturbing reports of a terrable mutation among the Mammary workers... it causes them to become mindless killing machines that seek to only further their numbers. So Immunity has sent a squad of their top agents to deal with the treat. However they now face overwhelming numbers and now face the possiblity of losing everything. There is talk of severing the MGD from the rest of the body inorder to prevent any serious threat to the body itself... however that decision is to be made by Nerv Central.
