League Battle

League Battle is a multiplayer mode in Splatoon 2. It replaces Squad Battles as an option for co-operative ranked play.

League Battles feature the same game modes as Ranked Battles, namely Splat Zones, Tower Control, Rainmaker, and Clam Blitz. The stages and modes for League Battles rotate every two hours and feature a different mode and stages. The stages selected for League Battles are not dependent on the stages in the monthly Ranked rotation.

For two hours, players team up in a group of two, called a pair, or four, called a squad, and compete with other groups to earn as many points as possible. At the end of the two hours, results are shown in a ranking system called League Power that acts the same as Splatfest Power or the Rank X system. Players get their initial League Power based on their performance in the first seven matches. Players must be Rank B- in Ranked Battles or higher to participate in League Battles. Unlike Squad Battles, a player's rank does not change, regardless of what rank they are.

Pairs are grouped up with other pairs, with two pairs on a team chosen at random. Squads play against another squad.

Groups that rank high enough will recieve commemorative medals, either Gold Medals,  Silver Medals , or  Bronze Medals.

Scheduled League rotation
During the finals of the fourth Splatoon Koshien Tournament, there was an announcement of scheduled League rotation. Since February 2019, every month there is a scheduled League Battle rotation announced on @SplatoonJP Twitter for Team of four with set mode and stages. The top 1st, 2nd, 3rd and 100th or 101st teams get to have a unique picture of their characters with their weapons and gear in one of the stages played. The pictures are posted in the @SplatoonJP Twitter.
