Bluefin Depot

Bluefin Depot is a multiplayer stage in Splatoon and Splatoon 3. It is an abandoned coal mine with railway track above it. A river splits the stage down the middle, with the spawn areas connecting the left and right paths.

Layout
Bluefin Depot is an abandoned coal mine consisting of four different levels, the two uppermost of which can only be accessed by the enemy team by grated walkways. The lowest level is divided by a body of water and requires traversing the third level to switch sides. It consists of two platforms that are separated from each other by a small body of water that cannot be jumped over. The level allows players to travel between both sides of the stage. Each team's base is comprised of two levels. The spawn point is located on the top level; it can only be reached via a grated walkway in the middle. The bottom level is where players can get to the different sides of the stage and can only be reached by a grated walkway on the opposing team's right.

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
The Splat Zone in Bluefin Depot can be found on the side that is closest to the ocean. Two ramps leading towards the Splat Zone are located on the other side of the stage. Walls have also been added on both sides of the stage. Blocks have also been added to the bottom level of the bases and to the lower level to even the ramp located on each side.

Tower Control
In Tower Control, the Tower starts in the center, above the water and can be accessed by an added bridge. Once claimed, it moves to the right and up the walls. Then, it crosses over to the left side and continues up until it reaches the goal. Inkable blocks are added to the uninkable block on the left of the spawn point.

Rainmaker
The Rainmaker is located in the middle of the stage. The control points are directly in front of the spawn points on each side. In this mode, there have been a few changes to the map, most notably the middle where the weapon is located. There are pathways, as well as a platform where the Rainmaker sits and ramps that allow players to easily move between the two sides of the stage. A box and grated walkway leading up to this section are added on the left.

Trivia

 * Evening and night variants of this map exist in Octo Valley, in the missions Octoling Uprising and Undeniable Flying Object, respectively.
 * At the end of Undeniable Flying Object, after the Octostriker has been defeated and the music stops, some unusual sounds can be heard: an erratic clanking and a faint moan, which are slightly louder towards the edge of the UFO. These sounds could also be heard when using Recon to explore Bluefin Depot during a Splatfest. Given Callie's comments on the stage, they may be the result of paranormal happenings or simply the deterioration of old structures.
 * Bluefin Depot is one of two stages to have appeared in an Octo Valley mission yet not be available to play multiplayer battles on at launch, alongside Kelp Dome.
 * In the Octo Expansion, Cap'n Cuttlefish refers to Bluefin Depot in Bust & Run Station.

Etymology
