League Play

Trueskill Matchmaking is a new Numerical system that is scheduled to be used for the first time alongside XP in Call of Duty: Black Ops II. similar to Halo and Starcraft, your League is determined by how many games you win or lose, lose often, and you'll risk being demoted to the League below you, win more, and your league will go up. David Vonderhaar, has tweeted out some of the Leauge emblems, but it is currently unknown which emblem links to which League.
