Octo Canyon (also known as Hero Mode) is a singleplayer game mode in Splatoon 2. It involves the player donning the Hero Suit handed down from Agent 3 (although both Hero Suits look dissimilar) and venturing into a hidden, underground canyon where the Octarians have relocated to since the events of Splatoon, to rescue Inkopolis Squares' stolen Great Zapfish and re-defeat the Octarian army.


After the Great Zapfish is stolen a second time by the Octarians, Marie recruits Agent 4 (Captain Cuttlefish and Agent 3 were out on a mission) to find the Great Zapfish and her missing cousin Callie. Agent 4 travels the underground lairs known as Octo Canyon to recover the Zapfish. Eventually , Agent 4 confronts DJ Octavio, who has brainwashed Callie. With Marie's help, Agent 4 is able to free Callie from Octavio's mind control shades and defeats him once more.


Octo Canyon functions in the almost exact same way as Octo Valley did, with the addition of new enemies and new mechanics. The Player is given many different weapon choices as the story progresses in Octo Canyon. They are given to Agent 4 from Sheldon, and they include the Hero Shot, the Hero Roller, the Hero Charger, the Hero Dualies, the Hero Brella, the Hero Splatling, the Hero Blaster, the Hero Slosher, and the Herobrush.


Many mechanics make a return in Octo Canyon that made their first appearance in Octo Valley, with the addition of various new mechanics. These include Ride Rails, Inkfurlers, and Bounce Pads.

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

Hero Suit

A new Hero Suit is worn by Agent 4. It is primarily neon-yellow and has headphones similarly shaped to that of the first hero suit. This suit acts like an armor collectible in that it allows the player to take damage that would normally kill them once- then it needs to regenerate. While regenerating the suit, the player is slowed down. While in certain missions, Agent 4 can find Armour. It comes in cases found in various parts of the level. You can have up to two cases on at a time and it allows you to take damage that would normally kill you. If you finish a mission with any amount of armour on, you are rewarded with 10 extra power eggs.

Hero Weapons

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. It can be upgraded twice with Power Eggs and Sardinium, increasing its capacity.

Splat Bomb

Octo Canyon's Splat Bombs functions like those found in Inkopolis. They are four-sided and look almost identical to those in Octo Valley. They explode a short while after hitting the ground.

Curling Bomb

The Curling Bomb works similar to the ones before the 3.0.0 update. They travel across the ground, bouncing off walls, and explode after a set amount of time. Holding down Button1 R.png will make 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 Power Eggs.


The Autobomb works just like the ones in Inkopolis. After hitting the ground, they will run towards any target they find in a certain radius, then start to explode. If they don't find a target, they will start exploding right away. They can be unlocked using Sardinium and Power Eggs.

Special Weapons

Special Weapons can be found throughout Octo Canyon in the form of a Canned Special, Upon collecting a Canned Special, a certain Special Weapon is immediately fully charged.


Unlike Octo Valley, there are three types of Collectibles.

Power Eggs

Power Eggs appear to be small, orange fish eggs that can be found throughout Octo Canyon. They can be collected by killing enemies, destroying crates, and shooting or running near individual ones scattered around the environment. They are used for upgrading equipment and weapons.

Sunken Scrolls

Sunken Scrolls are rolled up pieces of paper that can be found in Octo Canyon. They are long-lost drawings and other pieces of information that depict the history and lore of Inkopolis. One Sunken Scroll can be found in each level of Octo Canyon.


Sardinium is a new form of collectible in Octo Canyon. One can be found in each level, after each boss, and in each hub area. They are used to upgrade equipment and weapons with the Ammo Knights Enhancifier along side Power Eggs.


After watching the Credits, the player will unlock the full set of Hero Suit Replica Gear for use in online play. After completing all levels with a certain weapon, the player will unlock a replica of that weapon for use online.

As of Version 3.0.0, Callie also appears within Octo Canyon following the credits; when spoken to, she and Marie will share a variety of statistics relating to the player's most recent multiplayer matches, weapon statistics, and Salmon Run jobs.


  • If the player enters Octo Canyon as an Octoling they will revert back to their latest customization of Inkling they used, and switch back to an Octoling once the player returns to Inkopolis.
  • The Hero Suit Replica Gear will not be unlocked unless you finish watching the Credits. Skipping the Credits will not unlock the Gear, forcing you to re-watch them to unlock the Gear.
  • The "Mission Failed" jingle that plays when Agent 4 fails a mission has high-pitched vocals resembling an Octoling laughing.
