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 other power levels. 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 receive commemorative medals, either Gold Medals,  Silver Medals , or  Bronze Medals. These medals are awarded to the top 5%, 20%, and 50% of players for that rotation respectively.

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 three teams, plus one additional team, receive a unique picture of their characters with their weapons and gear at one of the stages played. The criteria for the additional team cycles every month, alternating between being the 101st team, the team with the median score overall, and the highest scoring bronze team. All rewards are based on the ranking for the Japan region. The pictures are posted in the @SplatoonJP Twitter.
