Planeptune Alley is an optional dungeon in Hyperdimension Neptunia Re;Birth3: V Generation whose plan is found during the post game in the Hyper Dimension by a Takanashi Pro chirper near Planeptune.


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.
