Jorge S Fernandez: "Another month, another Neptunia game; if Compile Heart isn’t churning over yet another new installment of the short-running yet bi-annual Neptunia franchise, they’re most likely re-releasing one of the previous games on either consoles, handhelds, or PC. This time, it’s the PC’s turn to receive a handheld port with the re-release of Hyperdimension Neptunia U: Action Unleashed. What does the U stand for? An in-joke about how the series has never found its way onto the Wii U, a joke that undoubtedly only Compile Heart finds hilarious."
VGChartz's Adam Cartwright: "Console wars have been around pretty much since the dawn of videogames, but the Hyperdimension Neptunia series makes light of these arguments by personifying consoles and their manufacturers as cute goddesses and has them battle it out for supremacy. It proved to be a sleeper hit for publisher Compile Heart, who after an initially shaky start with the first entry transformed the series into its most compelling franchise."
Idea Factory’s games are so often full of life, exploding user screens with vibrant color, beautiful art, memorable characters and addictive gameplay. Unfortunately, Hyperdimension Neptunia U: Action Unleashed does little justice to the Neptunia franchise.
SG Gaming Info writes: "Hyperdimension Neptunia U: Action Unleashed is a rather boring brawler title. While the game retains the franchise’s humour the combat gets boring quickly and the story isn’t that interesting."
