Port Mackerel is a close-quarters cargo bay map, featuring obstacles such as cargo containers, crates, and cargo vehicles that move back and forth. The cargo vehicles sometimes block the paths, but Inklings can spray ink on them and climb them as well. Starting from each team's Spawn Point on opposite sides of the symmetrical arena, narrow pathways lead into two open areas on both sides of the battlefield. Small, hidden pathways are also present on both sides of the stage, making good places to put Squid Beakons, or roost with a charger.
- Open Battlefields - This is where most of the combat takes place. Both open battlefields are separated from each other by another set of cargo containers. These battlefields, while being very open for vision, are still difficult to maneuver around for the beginning player because of the mats and a couple bumps. It is advised to climb on one of the cargo vehicles and jump on a matted storage crate from there, as it is higher ground and enemy ink cannot trap the player. However, as the mat prevents ink placement, the player cannot hide in their own ink.
- Side Passages - there are four Side Passages in this stage, two on your side, and two on the enemy side. They are all accessed on the left or right sides of the map and lead to small openings on the side of the Open Battlefields. The Side Passages are often forgotten parts of the map, particularly because they're mostly out of the action and they're only accessible from the area near the spawn points.
- Splat Zones - In this map, there are two Splat Zones, which are located on both open battlefields in opposite corners from each other. The player's team will need to cover both to be in control, but if they only have one covered, neither team will be in control. The moving cargo vehicles have been removed.
- Tower Control - The tower is located on the middle of the map. The tower will go straight forward and it will turn either left or right. The finish is up on top of the crate that is in front of the rival spawn point.
- Rainmaker - The Rainmaker is located at the middle of the map. The Rainmaker must be taken to the pedestal located on top of the cargo container in front of the rival Respawn Point. A couple platforms are supplied to make reaching higher ground easier, the pillar can only be access by either climbing the newly placed board on the backside of the container or jumping from the high ground.
- Splat Zones - TBA
- Tower Control - For the most part, it is the same as Splatoon. However, some changes are present such as the different sizes of some containers, as well as added in checkpoints. The first checkpoint is located after a few turns, right next to the cargo containers that splits the spawn point into two paths, as well as an opening accessible from one side path. The second checkpoint is located closer to the base, next to the same container. The finish point is reached after one more turn, and is next to the cargo container it was previously on top of in Splatoon.
- Rainmaker - TBA
- Clam Blitz - TBA
