Super Neptunia RPG is a role-playing game set in the Neptunia series' video-game-themed world, following its cast of console-inspired characters through a new story presented in hand-drawn 2D, side-scrolling visuals. Battles use a formation-based system in which characters' positions and skills shape how fights play out.

Its lighthearted tone and industry in-jokes remain central to the experience, wrapped around traditional RPG progression like leveling, equipment, and skill growth. Fans of the Neptunia series will recognize its cast and humor presented through a different visual and combat style.
