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.

The player selects a quest, after clearing it events will start, progressing the scenario. In the WORLD menu you can accept quest, check character equipment and other things. In addition, selecting a quest from WORLD shows various information such as clear conditions and enemy list. After selecting a quest, characters can be chosen. Up to two characters can participate, but it's possible to play with only one.
Upon entering the dungeon, clear conditions will be shown, and progressing further in the dungeon will make enemies appear. Defeating enemies will grant sometimes items, including recovery items that will help clearing the quest, as well as medals that when collected will bring advantages. Once the clear conditions have been fulfilled, the quest is cleared. The amount of experience received is based on actual activity during the quest.
This game is a 3D Action in which the goddesses can move freely and mow down enemies. When buttons are pressed with the correct timing you can easily connect combos, and if you launch enemies in the air you can execute air combos. However, the characters hit by enemy attacks have their clothing destroyed. In addition to the free-roam battle system, the player can also use up to two characters in battle and switch between them at will.
It allows the player to see ordinary conversation events between the characters. While it is not always necessary to see them, viewing these events can sometimes lead to other event or even new quests.

A world protected by the divine aegis of the four CPUs and the CPU candidates.
Even in this world the seeds of evil don't die out, and since brutal enemies along with ferocious monsters that appeared were quickly defeated by the collaboration between the CPUs and the CPU candidates, not only the goddesses themselves but also the inhabitants of Gamindustri ended up very bored.
Due to that, the goddesses discussed an interesting proposal...
