Splatoon/Saltspray Rig

Narrow winding corridors and large arenas are both present on this oil rig. With the map being symmetrically split down the middle, one team's approach to any area will directly mirror the other team.

Layout
Saltspray Rig consists of two large spawn platforms on either sides of a large central structure with a clear incline, being highest at the north point of the map and lowest behind the spawn point. The spawn area is quite high compared to the surrounding areas and is totally inaccessible to the enemy team, but the map's design makes both team's spawn areas quite close together. The spawn platform has long walls to block shots, and has several spots for players to drop down on to the main battlefield. Going forward leads to some winding paths, to one side is an exposed corridor that drops down on to a small arena, while heading up the hallway on the other side leads to a square behind the walls surrounding the top area.

The walkways form the paths that lead to the map's various areas of interest. They connect two distinct floors in this area outside of spawn: the higher platform that leads into the map's main field of conflict, and the lower floor which branches off to an oft-neglected rectangular area. This area is the lowest point on the map and is flat except for a few crates, and is within line of sight of both team's spawn platforms. Falling off the walkways results in instant death, but it is possible to use the elevation to perform aerial assault on enemies below. There are several crates and barriers for cover, as well as large signs hanging over the walkways to block shots. Other than the winding walkways, there are also two small elevators that move between the two floors at the center of this region.

The top part of the map is where both teams mainly clash at, regardless of the mode. It is a very key spot to control and is fairly defensible with walls surrounding the area and a small chokepoint being the main entrance into the region. However, attackers can also use the walls to their advantage, using the few inkable pipes and towers attached to the walls to swim onto them. The two towers in particular has a great view of the arena enclosed by the walls, making it a popular sniper spot as well as a decent alternate entrance into the region. A T-shaped wall is present at the center of the region with a single inkable surface leading to its top. Behind that arena is a huge square with a bunch of large crates that serve as both walls and platforms. A suspended grate sweeps high across the area, making for a hard to reach, albeit exposed vantage point.

Turf War
A couple of barriers are present in the top region that aren't in other modes.

Splat Zones
The zone covers a large area that includes half the central arena and part of the area outside the bottleneck. Two blocks have been added below the sniper perches to allow defenders an easier time at retaliating against snipers.

Tower Control
The tower is located at the back of the central arena. It loops around the T-shaped wall, passes through the bottleneck, descends down to the lower level and comes to a stop at a bend on the walkway. Inkable blocks have been added to either side of the walls surrounding the center for better mobility in and out of the region.

Rainmaker
The Rainmaker bubble starts off in front of the bottleneck into the central arena. The spawn platforms have been heavily altered, with a new area added near the spawn point for the end goal. Inkable walls have been added at the drop-off points from the spawn platform so that attackers can reach it from the walkways. There are also additional barriers and the long hallway trailing off from spawn has been walled off. Lastly, there is a huge Rainmaker-forbidden area that encompasses the entire topmost region with the crates and the sweeping grate. The timer counts down quickly there, and dying in that area causes the Rainmaker to respawn in its initial position.
