Turf War is a game mode in Splatoon in which the goal is to cover as much of the ground with your team's ink as possible.
Walls do not count in this mode. Certain materials like Glass and Water cannot be covered with Ink. After the match is over, the matches are judged by a cat named Judd.
8 players will split into two teams of four. Using the weapon of their choice, the player will attempt to cover as much ground with their ink as possible. Taking out an opponent will splash the general vicinity in which they were splatted with your team's color ink.
