Octo Canyon (also known as Hero Mode) is a single-player game mode in Splatoon 2. It involves the player donning a Hero Suit and venturing into a hidden underground canyon where the Octarians have relocated to since the events of Splatoon, to rescue Inkopolis Square's 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 to find the Great Zapfish and her missing cousin Callie. Agent 4 travels the underground lair known as Octo Canyon to recover the Great Zapfish. Eventually, Agent 4 confronts DJ Octavio, who has brainwashed Callie. With Marie's help, Agent 4 frees Callie from Octavio's hypnoshades 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. They are given to Agent 4 from Sheldon, and they include the Hero Shot, Hero Roller, Hero Charger, Hero Dualies, Hero Brella, Hero Splatling, Hero Blaster, Hero Slosher, and Herobrush.


Many mechanics make a return in Octo Canyon that made their first appearance in Octo Valley, with the addition of various new ones. 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 as an armor collectible in that it allows the player to take damage that would normally splat them once - then it needs to regenerate. While regenerating the suit, the player is slowed down. While in certain missions, Agent 4 can find armor. It comes in cases found in various parts of the level. The player can have up to two sets of armor on at a time and it allows them to take damage that would normally splat them. If a mission is finished with any amount of armour on, ten extra Power Eggs are rewarded.

Hero weapons

Each hero weapon can be unlocked by completing the level Sheldon has requested them to use it (excluding the Hero Shot which is the default weapon) and upgraded by using 1500 Power Eggs and 3 Sardinium.

  • S2 Weapon Main Hero Shot Replica.png Hero Shot - The default weapon and a P90-esque shooter-type weapon. It is similar to the Splattershot but fires slower than it when not upgraded. It can be upgraded twice using Power Eggs and Sardinium, increasing the fire rate.
  • S2 Weapon Main Hero Roller Lv. 2.png Hero Roller - A modified Splat Roller similar to the Carbon Roller. Can be upgraded once with Power Eggs and Sardinium to increase its damage and fling speed.
  • S2 Weapon Main Hero Charger Lv. 2.png Hero Charger - A modified Splat Charger. Can be upgraded once with Power Eggs and Sardinium to increase its charge speed.
  • S2 Weapon Main Hero Dualies Lv. 2.png Hero Dualies - Modified Splat Dualies. Can be upgraded once with Power Eggs and Sardinium to increase its firing rate.
  • S2 Weapon Main Hero Slosher Lv. 2.png Hero Slosher - A modified Slosher. Can be upgraded once with Power Eggs and Sardinium to increase its firing speed and damage.
  • S2 Weapon Main Hero Splatling Lv. 2.png Hero Splatling - A modified Heavy Splatling. Can be upgraded once with Power Eggs and Sardinium to increase its charge speed.
  • S2 Weapon Main Hero Blaster Lv. 2.png Hero Blaster - A modified Blaster. Can be upgraded once with Power Eggs and Sardinium to increase its firing rate.
  • S2 Weapon Main Hero Brella Lv. 2.png Hero Brella - A modified Splat Brella. Can be upgraded once with Power Eggs and Sardinium to increase its durability and brella recovery time.
  • S2 Weapon Main Herobrush Lv. 2.png Herobrush - A modified Octobrush. Can be upgraded once with Power Eggs and Sardinium to increase its flick speed, damage, and mobility.

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 Bombs

S2 Weapon Sub Splat Bomb.png Splat Bombs function 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 Bombs

S2 Weapon Sub Curling Bomb.png Curling Bombs work similarly to the ones before Version 3.0.0. They travel across the ground, bouncing off walls, and explode after a set amount of time. Holding down Button1 R.png 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 Power Eggs.


S2 Weapon Sub Autobomb.png Autobombs work just like the ones in Inkopolis. After hitting the ground, they run towards any target they find in a certain radius, then start to explode. If they do not find a target, they start exploding right away. They can be unlocked using Sardinium and Power Eggs.

Special weapons

A variety of 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.
Specials that can be found are:
S2 Weapon Special Tenta Missiles.png Tenta Missiles
S2 Weapon Special Sting Ray.png Sting Ray
S2 Weapon Special Splashdown.png Splashdown
S2 Weapon Special Ink Storm.png Ink Storm
S2 Weapon Special Splat-Bomb Launcher.png Bomb Launcher


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. If the player has already found the sunken scroll in a mission and finds it again, it will be gray in appearance and instead of acquiring it again, the player will receive 10 Power Eggs.


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 alongside Power Eggs. If the player has already found the Sardinium in a mission and finds it again, it will be gray in appearance and instead of acquiring it again, the player will receive 5 Power Eggs.


After watching the credits, the player unlocks the full set of Hero Suit replica gear pieces - the Hero Headphones Replica, Hero Hoodie Replica, and Hero Snowboots Replicas - for use in online play. After completing all levels with a certain weapon, the player unlocks 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 share a variety of statistics relating to the player's most recent multiplayer matches, weapon statistics, and Salmon Run jobs.

Fresh Start


  • If the player enters Octo Canyon as an Octoling, they revert to their latest customization of Inkling they used, and switch back to an Octoling once they return to Inkopolis with the ink color they had in Octo Canyon.
  • The Hero Suit replica gear is not unlocked unless the credits are watched all the way through. Skipping the credits does not unlock the gear, forcing the player to re-watch them to unlock it.
  • The "Mission Failed" jingle that plays when Agent 4 fails a mission has high-pitched vocals resembling an Octoling laughing.
  • Despite not showing it during the mission, the timer in Octo Canyon records in milliseconds. Because of this, it is possible for two weapons to share the record time on a level.
