List of unarmed missions

These missions in the Octo Expansion and Return of the Mammalians require the player to enter the mission without any main, sub, or special weapon. Typically, these missions utilize a mechanic that does not require any equipped weapons (e.g. an Ink Cannon in I03E01 No Whammy Station), or offer challenges in which a weapon would defeat the point of the challenge (e.g. C04 Move It Move It Station). Some missions that begin unarmed allow the player to collect canned weapons or canned specials over the course of the mission.

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