This will be a mode that players can play either in groups of two or four, and it will present you with a two-hour period in which your group competes with other groups to see how many points you can earn. Because the results of that League Battle play will be displayed in a ranking at the end of every two-hour period, we can give players goals to strive for, and hope to encourage them to keep competing and pushing.
Sounds really neat, more details are starting to trickle in! :D
