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. Your only available weapon in Hero Mode is the Splattershot. There are multiple different tools or Mechanics that make an appearance in the Singleplayer campaign.


  • The player's Inkling wears a vest, headset, and futuristic shoes during Hero Mode. They cannot be purchased, but replicas are unlocked after completing Hero Mode.
  • Before or after any boss battle, creepy moaning and clanging can be heard in the background. This is assumed to be proof that the Octarian civilization is falling apart
