Game Dimension is a dungeon in Hyperdimension Neptunia Re;Birth3: V Generation that the player starts in at the very start of the game. After completion of the dungeon, there is no way to return to it until a New Game Plus.


The following items can be found in the dungeon. Items in the treasure chest can only be obtained once. Numbers are marked on the map to denote those treasure chests.

Note 1: Hidden Items are now replaced with hidden item blocks. All hidden item blocks are present in the dungeon at all times. However, only one of the hidden item block drops item(s) at any given run through the dungeon. They will however give credits if you jump to them.

No quests to do in this dungeon.



After diving into the game, Neptune investigates the dungeon. While wandering, some monsters attack her. Nepgear says that she may be able to use her N-Gear to extract some data from the game if Neptune fights them. After gathering data from the battle, Nepgear finds out that the game got messed up because of a virus. Her N-Gear also gets a strong reaction from the far end of the dungeon. Thinking this might be the root of the virus, Neptune makes her way through the dungeon. At the end of the dungeon, she locates the virus and confronts it. Although it summons numerous monsters to stop her, Neptune manages to beat them all easily. She then dives out of the game.
