Daedalus Tower consists of eight floors that descend underground. The top floor, where the game begins, is the location of Micon Town and provides a couple services: a village elder who can save the game's progress, a healer, a Weapon Shop, an Armor Shop, and a Heretic Mansion. Daedalus Tower's elevator is initially inoperable and becomes usable only after the Minotaur, the dungeon's boss, is defeated.
Daedalus Tower and Micon Town appear as locations in "Devil Buster", a video game that the Protagonist plays at the beginning of Megami Tensei II. The Protagonist takes control of a male hero and female partner and is able to level them up, recruit Demons, and purchase equipment within the game world. If Devil Buster's characters die, the game ends but retains any levels, Demons, and equipment acquired, allowing the Protagonist to proceed where he last left off from the beginning of Daedalus Tower.
