Ranked Battle terrain
In Ranked Battles, specifications for the terrain or placement of objects are different between the modes; these changes create new paths or new objects to take cover behind.

Splat Zones
There are two Splat Zones, both located underneath the glass areas. An uninkable ramp is added to allow access to the opposing team's base.

Tower Control
The Tower starts in the middle of the stage, replacing the Bumper normally there. When advancing, the Tower goes left then straight, closer to the opposing team's side. It then goes right and continues going until it reaches the goal. The large glass areas in the middle are removed and a ramp is added in the middle of the opposing team's base.

Rainmaker
The Rainmaker is located in the middle of the stage, replacing the Bumper normally there. The checkpoints are located in the open area to the right, and to the far left on the opponent's raised area. A ramp is added to the far left to allow access to the checkpoint. The pedestal is located on the first drop The right of the spawn areas have been altered slightly, having an uninkable path being the only way to get to the pedestal. An Inkrail is added to the far right of spawn.

Clam Blitz
The Clam basket is located to the left of the spawn, two drops down. An uninkable ramp has been added just behind the basket to help access the platform behind it.
