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.

Turf War is the only mode in which every part of Saltspray Rig can contribute to a victory, and is clearly what this map is mainly designed for. The spawn area is inaccessible but makes up a fair amount of turf, which is usually inked as players take the routes to reach the center. The most important region of the map is the top. The northernmost part of the map is a wide open area that can give a lot of turf points that is also relatively defensible, so expect it to be heavily contested for the whole match.

During the initial teamfight, long-ranged weapons like chargers should head for the platform overlooking the top arena or the top of the walls surrounding it, as it gives the best view of the vital area. Everyone else will likely clash in front of the chokepoint leading into the north platform. The barrier here forces you to strafe around it to fire at the enemy, which in turn exposes you to up close to enemies on the other side. You can also use the lifts below or jump around the barrier off the edge for a sneak attack. Jumping into the arena using the sniper perch is a slower alternate path, but lets you fire at foes at the chokepoint.

If your team manages to win the fight for the top area, first secure the entire zone leading to the large platform with the crates. The enemy has many avenues to attack this region from, but you can see all of them coming if you've covered the area in ink. Save the shipping crate area for lulls in the match to charge up your specials. A Sprinkler on top of the moving grate can spread ink over a wide area while being tough for enemies to destroy. A player can also do the same, but must eventually drop off the grate to refill. If you have Beakons, hide them under the ledge leading into the area or behind some crates to provide access to teammates in case enemies manage to control the paths outside the top area. The crates also provide cover and height for defenders when the enemy team tries to push into this region.

If you're trying to claim the top region from the enemy team, you have several options to attack. The chokepoint is the safest spot as it limits where enemies within the region can attack you from. The enemy sniper perch is a concern as they can see you, but you can quickly duck out of sight using the T-shaped wall. Snipers on the perch can ink the area underneath with near impunity, but using the perch to drop into the arena is dangerous, as enemies at the back can spot you sooner and you're very exposed when dropping to the ground. There's also always a risk with enemies ambushing you from behind. Due to how defensible the top area is, the winning team may extend outward to cover more turf while leaving one or two players to defend, during which a concentrated blitz may push through. Use an Echolocator or simply acute observation to determine when it's time to push.

Other than the top area, the paths leading up to it as well as the small platform to the south can also contribute turf, but it's hard to match the huge area of turf of the northern area. They are fairly low priority, but a good place for the losing team to charge up their specials. If the enemy is adamantly turtling within the top region and no pushes are successful, inking everywhere else can either force them out of hiding or even overcome their point lead if you're really thorough. These areas are in relatively low points on the map, so watch out for ambushes from above.

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.
