Forestial Promises

**Forestial Promises** is a single player game mode in Splatoon 4. It involves the player donning a Hero Suit D9 and venturing into the Abandoned Humanity and Outer Coralia to defeat the Sea Band Brigade and their robot assistants. It is only available via the DLC.

## Story

An Inkling, Octoling, or cuttleling, accompanied by the AI assistant R.U.I.N (Reused Under Instructor's Name), is a normal organism who just moved to New Coralia, previously called Aura Boralious. They go to ride the train station, but end up falling asleep, and they wake up at the trains final stop, dubbed "!&\*(#!", later to be found out as the Abandoned Humanity Site. There, they get off the train and enter the gateway to the main area of the site, only to be greeted by it's abandoned AI, who's dubbed itself R.U.I.N. There, the ink/octoling and R.U.I.N.s system explore some of treehouses in the forest, until Agents 5, 6, and 7 (Shiver, Big Man, and Frye) find the player and introduce themselves, dubbing that their boss sent them to come to retrieve New Agent 9 (the player) and to take them back to the Squid Sister's camp.

However, right as the 3 agents are about to take the player to the Squid Sisters camp, they're interfered by Sea Bait, New Coralia's current idols. They're accused of trying to take their land they were going to use as Outer Coralia for the less fortunate people of New Coralia to live at, and they attempt to use a brainwashing song using Fluther's flute and Sqool's microphone to brainwash the group into giving up and joining them, and it works on Agent 5 (Shiver). Agent 5 joins Sea Bait and leaves the group, causing Agent 7 (Frye) to get upset and storm off. Agent 6 (Big Man) goes after her, which leaves the player nothing to do but explore, which is when the player find kettles all around the site.

the player have to finish section 1 of the site before the full Sea Ring Brigade is introduced, which comprises of Member 1 (Fluther), Member 2 (Sqool), Member 3 (Daria), and New Member 4 (Shiver/Agent 5), who now has magenta colored accents opposed to blue. There is also their captain, Rita, but she is "busy and will be back soon." the player have to fight all 4 of them, with the battle intensity increasing the closer the player get. After the player beat Agent 5, Agent 7 stays behind with her, meaning the player lose Agent 7's use until the final fight.

After beating all of the Sea Ring Brigade, Agent 7 reappears with a cured Agent 5, who confronts the Sea Ring Brigade. From there, the remaining Sea Ring Brigade gets frustrated, and takes the fight to the Auditorium, which is where they all fight Agent 9 at once with their animal surpluses, proving they can't be beat.

Once beat however, they'll finally give up and let the player have the land, which is when they'll finally hear the player out, and realize how stupid they were being. However, that's when the Drone Moles will emerge and tear up the land and everything they'd done, resetting their plans, and crushing the train station. The Drone Moles are being controlled by someone else however, which is their captain, and the player have to fight their captain to be able to leave.

After beating the Drone Moles, the player have to rebuild the train station, and then the player can go back to New Coralia.

## Gameplay

The Abandoned Humanity Site acts the same way as previous single player modes. They can choose the option to pick their weapons for levels however, just like Return of Mammalians. They are given to Agent 9 from R.U.I.N.

### Mechanics

Comparing to the Hero Mode of the previous three games, Forestial Promises has a story like Return of the Mammalians, with the player not particularly having to beat every kettle. However, there are 3 different types of kettle-like the story mode before-and those are Bronze, Silver, and Rose Gold Kettles, which also serve as the boss kettles. Upon entering a mission, R.U.I.N. explains the rule of the level with a dialogue, and he then lets the player select the playerr weapon from the 2 recommended ones he has prepared, and then he lets the player pick the playerr desired ink color from the 3 he gives the player before the player start the mission.

## Equipment

Similar to Octo Valley and Octo Canyon, players wear the Hero Suit and use a wide variety of weapons.

### Hero Suit D9

Hero Suit D9 is of course worn by Agent 9. It's made of a holographic material and has headphones similar to the Agent 4 headphones and Neo Agent 3 headphones. The suit acts as the previous suits, with the player being able to get hit once before having to regenerate. While regenerating the suit, the player is slowed down. While in missions, Agent 9 can find armor. It comes in sardine like cases found around the level. The under-suit style of the Hero Suit is more for lounging around, with a baggy t-shirt and tennis shorts and an ink tank resembling a ziploc bag attached to the backpack that holds everything.

### Hero Weapons

* Hero Shot - The default weapon and a shooter-type weapon.
* Hero Brush - The hero version of the Octobrush.
* Hero Dualies - The hero version of the splat dualies.
* Hero Wringer - The hero version of the dread wringer
* Hero Stencil - The hero version of the Gello Brush-Pen.

### Ink Tank

The Ink Tank contains the ink consumed when using main weapons or sub weapons. Its ink supply can be replenished by swimming in ink.

### Splat Bombs

Splat Bombs function like those found in Splatsville. They are four-sided and look almost identical to those in Octo Valley. They explode a short while after hitting the ground. They can be unlocked with Sardinium and Upgrade Points.

### Curling Bombs

Curling Bombs work similarly to Splat Bombs, they travel across the ground, bounce off walls, and explode after a set amount of time. Holding down  makes them travel for a shorter distance before exploding, though unlike the current Curling Bombs, it does not increase the blast radius. They can be unlocked with Sardinium and Upgrade Points.

### Burst Bombs

Burst Bombs work similarly to Splat Bombs, but they detonate once they hit the ground, a wall, an enemy or an obstical. They can be unlocked with Sardinium and Upgrade Points.

### R.U.I.N.

R.U.I.N. can make sound baits to distract enemies, as well as coding into their systems to break them down for 3,000 power eggs when the player're struggling on a level/enemy.

### Special weapons

A variety of special weapons can be found throughout Humanity Site in the form of canned specials. Upon collecting a canned special, its respective special weapon is immediately fully charged. Meanwhile, the Hero Gear comes with a Splashdown special that can be charged up by painting turf - although having a charged Splashdown will not count as having a Canned Special in regard to the bonus Power Eggs gained at the end of a stage.

## Collectibles

Unlike Return of the Mammalians, there are four types of collectibles.

### Power Eggs

Power Eggs appears to be small, orange fish eggs that can be found throughout Alterna. They can be collected by killing enemies, destroying crates, and shooting or running near individual ones scattered around the environment. They are used to allow Little Buddy to remove the Fuzzy Ooze, as payment for any fees missions can have, and to run the Shell-Drone.

### Sunken Scrolls

Sunken Scrolls are rolled up pieces of paper that can be found in Alterna. They are long-lost drawings and other pieces of information that depict the history and lore of Splatoon's World. The Sunken Scrolls can be found in the overworld of Alterna.

### Sardinium

Sardinium is a collectible that can be used to unlock upgrades for the playerr Hero Gear. They can be obtained by beating levels and resemble metallic sardines.

### Gears

Gears can be found scattered all over the site in treehouses and levels. They can be used to upgrade R.U.I.N.s system to give him advances such as louder sound baits and quicker hacking time.

## Trivia

* If the player depend on R.U.I.N.s hacking ability for the story mode, the player will be unable to fight Sea Ring Deep Cut, which is a secret boss fight after the player beat all levels and the game where the player battle all of Deep Cut in different phases if they were all controlled by Sea Bait.
