GA:
Seeing as Hyperdimension Neptunia U: Action Unleashed is the fifth Hyperdimension Neptunia game I've reviewed on the Vita in the last year, I feel like I can write at least part of this review on autopilot. Lots of referential gaming jokes…blah blah blah…the game doesn't just straddle the line between mocking fanservice and indulging in it, it pogos constantly from one side to the other…yadda yadda yadda…you fight Pac-Man ghosts and Tetris pieces and on and on and on. Basically, you could almost take my last review, of Hyperdevotion Noire, and just sub in this title for that one.
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."
