Octo Valley (mode)

Hero Mode is a single-player game mode in Splatoon. It involves the player donning the Hero Suit and venturing into Octo Valley to rescue Inkopolis' stolen Zapfish and defeat the Octarian menace.

Story
After the Great Zapfish, Inkopolis' primary power supply, is stolen, Cap'n Cuttlefish employs a Splatoon of Inklings to travel to the Octarians' secret underground base and retrieve it. Players assume the role of Agent 3 and traverse the treacherous landscape of Octo Valley in order to reclaim various lost Zapfish, Sunken Scrolls, and Power Eggs.

Gameplay
Hero Mode incorporates various puzzle mechanics and 3D-platforming elements. Gameplay has been compared to Turf War and Super Mario Galaxy, in the sense that it sees players splattering Ink to defeat enemies, transforming into squids, and traversing floating platforms. The Player's only available weapon in Hero Mode is the Hero Shot, a modified version of the Splattershot.
