Undertow Spillway

Undertow Spillway is a multiplayer stage in. It is also one of the stages that can have Tricolor Turf Wars.

Layout


Undertow Spillway is an abandoned underground flood bypass in Splatsville that was renovated into a Turf War stage. The spawn area features a wide area of turf that goes far to the right. The first drop is accessible to the other team via an uninkable ramp and goes also as far as the spawn area. The drop after that is an open area and to the left allows access to a raised area and an uninkable raised area. To the right of the open area is a small drop to another open area. The middle is two open areas separated by a wall in the middle.

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 has 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 the 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.

Splatoon 3
Undertow Spillway was added with the launch of.

Splatfests
Undertow Spillway was available in the following Splatfest as the Tricolor Turf War stage in :


 * Spicy vs. Sweet vs. Sour

Big Run
Undertow Spillway is where the third Big Run took place. Its layout adds many inkable blocks, plus ten Gushers which the Salmonids use to enter the stage. Six Gushers are active at low tide, three at medium tide, and two at high tide. As usual, there are three tides; low tide takes place in the middle of the stage with the Egg Basket placed on the sloped ledge in the center, medium tide sets players on the raised area just outside of Team Alpha's spawn, and high tide sets players in the spawn area with the majority of the stage flooded. For this Big Run only, the Egg Basket's hitbox is expanded downward due to its placement on raised platforms across all tides. The only Known Occurrences that can occur on this stage are Fog, The Mothership, and Rush.

Quotes

"Squid Research Lab reporting from Undertow Spillway, a former flood bypass that's now used for Turf War battles! This abandoned facility is another shining example of upcycling, as the varied terrain lends itself to strategic and hard-fought skirmishes among Splatsville locals."

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, while both English localizations of Splatoon used the same stage names before all regions started using one localization from onward.
 * The stage was the first stage introduced in to be used in Tricolor Turf War.
 * It is also the first stage to be used in both Tricolor Turf War and Big Run.
 * The internal codename for this stage in the game files is "Temple".
 * This stage strongly resembles Tokyo's Metropolitan Area Outer Underground Discharge Channel, the main chamber of which is often referred to as an "underground temple" or "floodwater cathedral", hence the internal stage name of "Temple".
 * During Big Run, as the players get launched onto the stage, an alarm-like sound can be heard.
 * Additionally, the Grizzco helicopter stays immobile the entire time, unlike in other stages.
 * This was the first Big Run stage to take place indoors. It is also the only Salmon Run stage in any Splatoon game where the time of day does not change to night during a Known Occurrence; instead, the lights on the ceiling dim.
