Bluefin Depot

Bluefin Depot is a multiplayer stage in Splatoon. It is an abandoned coal mine with railway track above it.

Layout
Bluefin Depot is an abandoned coal mine consisting of 4 different levels, the two uppermost most of which can only be accessed by the enemy team by grate walkways. The lowest level is divided by a body of water and requires traversing the third level to switch parts. The lowest level of Bluefin Depot is most likely where most of the fighting between the two teams will take place. It consists of two platforms that are separated from each other by a small body of water that cannot be jumped over. The level just above the lowest level of Bluefin Depot is where all traveling between both sides of the level below is made. Chargers cannot snipe too much from here, mainly because of the iron bridge running over the middle of the map. Each team's base is comprised of a top level and a bottom level. The top level is where players respawn; 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 depot and can only be reached by a grated walkway on the opposing team's right. In Rainmaker, a box and grated walkway leading up to this section is added on the left.

Ranked Battle Terrain
In Ranked Battle, 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's closest to the ocean. Two ramps leading towards the Splat Zone are located on the other side of the map. Walls have also been added on both sides of the map to help each team attack the other team, and for mobility. Blocks have also been added to the bottom level of the bases prevent sniping from each base 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 water. Once claimed, it will move to the right and up the walls. Then, it crosses over to the left side and continues up until it reaches the goal.

Rainmaker
In Rainmaker, the weapon is located in the middle of the map. The control points are directly in front of the spawns on each side. In Rainmaker there have been a few changes to the map. Most notably the middle where the weapon is located. There are path ways as well as a platform where the Rainmaker sits. There are also ramps where players can get on each side of the map with ease.

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 are also 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.
