List of unarmed missions

These missions in the Octo Expansion and Return of the Mammalians require the player to go through parts of, or sometimes the whole, mission without any main, sub, or special weapon. Typically, these missions utilize a mechanic that does not require any weapons (e.g. an Ink Cannon in No Whammy Station) or offer challenges in which a weapon would defeat the point of the challenge (e.g.  Move It Move It Station).

Unarmed missions are marked with an icon on the selection screen of the equipper.
