Aura Gate 2 Story
Source: An archive of Minato Kushimachi's self-credited Aura Gate 2 dialogue, story, and NPC encounters of note.
The Aura Gate 2 campaign "Hollow World" was originally released in sequences of ten floors over the course of a year, starting from April 2019 and ending in April 2020.
Unlike the other Aura Gates, Aura Gate 2 has fixed layouts, interactive NPCs which change as the player makes progress, and traditional Wizardry traps in a fifty floor dungeon that serves as a post-game of sorts to D2 Megaten's conventional, mobile auto-battler gameplay.
It follows a structure not unlike that of Digital Devil Story: Megami Tensei's "endless" dungeon with D2 Megaten's press turn combat and creative, puzzle-like bosses resembling the challenges of Shin Megami Tensei V.
