The Solid Gold limited-time mode may now be over, but Fortnite players don't have to wait very long to take part in the game's next special event. Epic is kicking off another limited-time mode for Battle Royale on PS4, Xbox One, and PC today, March 8, and this one promises to be one of the most competitive yet.

Battle Royale's next limited-time mode is called Teams of 20. As you could probably gather from its name, this new game mode still features 100 players total, similar to a typical match in Battle Royale, but this time they're divided up into five teams of 20. You can watch the brief announcement trailer for the new game mode above.
