The top Call of Duty teams in the world will gather in Los Angeles on March 28 to battle in this year's Call of Duty Championship. The tournament, sponsored by Xbox, has a $1 million prize pool and is centered around this year's game, Call of Duty: Ghosts.

The top teams will be chosen from qualifier rounds in North America, South America, Europe, Africa, Asia and Australia. The preliminary rounds begin this month - a full list is available over on MLG - with a total of 32 teams being chosen to go on to LA for the finals after the qualifiers.

The road to the finals will be broadcast on both Xbox Live and MLG.tv, as will the finals themselves. Last year's winner, Fariko Impact, walked away with $400,000.
