In this mode, two teams of four battle for control of the tower. The towers begins in the center of the map, and once a player from either team stands on the tower, it will start moving along a rail towards enemy territory. If a team loses control of the tower, the tower will stop moving, then begin to move quickly back to the center. In addition, the tower moves more quickly along sections of rail that have already been traversed.
There is a time limit of 5 minutes for each match. The team which manages to either move the tower all the way to their enemy's base (resulting in a knock-out win), or to move the tower farther than the opposing team within the time limit will win the match.
There is a grate around the central platform of the tower, allowing the player on top of the tower more moving space but also causing them to be more exposed to enemies below.
The tower plays a gentle jingle when moving, somewhat like an ice cream truck.
This mode rotates out with Splat Zones and Rainmaker every four hours along with the stages in the Ranked and Regular Battles.
