Hyperdimension Neptunia U: Action Unleashed (超次元アクション ネプテューヌU, lit. Super Dimension Action Neptune U) is a spin-off action game for the Hyperdimension Neptunia series. The world of Gamindustri is protected by four goddesses and their pupils. The goddesses and their helpers are powerful enough to defeat any monster without breaking a sweat, and with great power comes great boredom. When something comes along that can spark the interest of the goddesses, a story is set in motion.
