League Play is a new numerical system that is used for the first time alongside XP in Call of Duty: Black Ops II. A player's league is determined by how many games they win or lose. If they lose often, then they'll risk being demoted to the league below. If they win often, then they will be promoted to the next League.
Currently, there are two different Series to compete in. These are the Champions Series and the Moshpit Series.
