Undertow Spillway is a multiplayer stage in Splatoon 3. It is an abandoned underground flood bypass in Splatsville that was renovated into a Turf War stage.

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.

In Splatoon 3, checkpoints have been added:

	Location	Timer
Checkpoint 1	The first checkpoint is just before it turns left, right next to the starting position.	10 Seconds
Checkpoint 2	The second checkpoint in the middle of the upper left area.	12 Seconds
Checkpoint 3	The third checkpoint is located on the upper middle area.	12 Seconds

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.

Version history

Version	Adjustments
1.2.0	— Removed the box on top of the grating in Splat Zones because of an issue where attacks would pass between the box and the terrain despite looking like it blocked attacks from below.
2.0.0	— Changed some parts of the Turf War mode terrain. Deleted part of the terrain on the left-hand side when looking from the player start areas. Added ramps to allow for invading opponent areas.

Trivia

• This is the first stage to have different names between both Spanish localizations. Both French localizations have used different names for certain stages since the launch of Splatoon, while both English localizations of Splatoon used the same stage names before all regions started using one localization from Splatoon 2 onward.
