is a series of role-playing video games produced by Compile Heart and Idea Factory, which revolves around and parodies the real-life video gaming industry usually from a Japanese perspective along with parodies of other forms of Japanese otaku subcultures. The series has also branched off into other forms of media, such as a manga, light novel and an anime.
The series debuted in Japan on August 19, 2010, with the video game of the same name for the PlayStation 3, and received sequels: Hyperdimension Neptunia mk2 (2011), Hyperdimension Neptunia Victory (2012), and Megadimension Neptunia VII (2015) as the last of the main series, until the release of Hyperspace Neptunia Unlimited (2026). All previously released main games have been remade at least once (such as the first three as the "Re;Birth" trilogy) and since then multiple spin-offs and crossover games have also been released for various platforms.
An anime television series adaptation, titled Hyperdimension Neptunia: The Animation, aired in Japan between July and September 2013. An OVA, titled Nepu no Natsuyasumi, was released in July 2019. A second OVA, titled Nep Nep Darake no Festival, was released in October 2022, and third OVA, titled Hidamari no Little Purple, was released in April 2023.
Setting
Games within the series takes place in the world of Gamindustri (a pun on "game industry"), which is divided into four regions/nations, each ruled by one Goddess CPU: Planeptune, Lastation, Lowee, and Leanbox. Each region is completely different from the others in appearance and atmosphere, with each representing a specific video game console. Lastation represents the PlayStation, Lowee represents the Wii, and Leanbox represents the Xbox, while Planeptune represents the cancelled Sega Neptune. In the beginning of the story, the four goddesses are fighting each other for "shares" in a war known as the Console War. Shares are the manifestation of the belief citizens put into their goddess, and without shares, a goddess dies. Because some of the games feature time and/or dimension travel there are slight differences in the settings for each title.
Development Prior to Q3 2009, Compile Heart was conceptualising a new RPG project centred upon character designs by Tsunako, with the intention of collaborating with a partner company. This game was originally planned to feature three princess sisters and a protagonist. However, the partnership deal fell out, and as a result the project plans were redesigned and eventually became "Neptunia" close to the end of 2009 following the completion of Trinity Universes development. During the early stages of the project, the characters Noire and Blanc were originally coloured red and blue respectively, however their colour schemes were changed to black and white so that they could better fit in with the new game setting and plot.
The release of the first sequel to the original game, Hyperdimension Neptunia mk2, saw the introduction of a reworked game engine and the replacement of various components such as the battle system and dungeons, which were completely rebuilt from scratch. Hyperdimension Neptunia Victory later built on this, with the parts from mk2 which were considered "weak" by the developers removed and improved, eventually setting Victory as the foundation for the design of future titles within the series. Following Compile Heart's collaboration with David Production to produce the Neptunia television animation series, the developers were able to change their approach to direction and script-writing based on their experience with the anime development staff, which resulted in the changes to the narrative found in the Re;Birth games on PlayStation Vita.
Release history Hyperdimension Neptunia is the first game within the series, with the name originally derived from the scrapped Sega Neptune which combined the Sega Mega Drive/Genesis and Sega 32X into one unit, originally scheduled for release in 1994 or 1995 before the project was dropped after the release of the Sega Saturn.
There are two sequels which have been released under the names Hyperdimension Neptunia Mk2 and Hyperdimension Neptunia Victory. Another game, titled , was released on June 20, 2013, for the PlayStation Vita in Japan and it was released in the west in June 2014 as Hyperdimension Neptunia: Producing Perfection, developed by Compile Heart, Idea Factory and Tamsoft.

Games
Main series Hyperdimension Neptunia (2010)
The game that introduced the series premise. Since its release, the game's story has always remained standalone in the isolated "Superdimension", never receiving a true sequel, as the games from mk2 onwards take place in a separate "Hyperdimension" universe with its own storylines, direct sequels and connected multiverses.
The game was remade as Hyperdimension Neptunia Re;Birth 1 released in 2013 with a modestly rewritten story and a combat system inspired more by Victory, Hyperdimension Neptunia Re;Birth 1 Plus in 2018, and Neptunia re★Verse in 2020, which in itself is based on the first Re;Birth game.
Hyperdimension Neptunia mk2 (2011)
The second game in the series and first to introduce the Hyperdimension timeline. It introduced gameplay mechanics, new characters, and lore reinterpretations of the previous ones, rebooting the storyline which has since became the mainline universe for the rest of the series. The game's plot tackles more about the major consequences of video game piracy, albeit presented in a black-and-white manner, while maintaining a slightly darker tone and serious storyline, albeit occasionally interjected with moe' tropes of its era.
It was later remade as Hyperdimension Neptunia Re; Birth 2: Sisters Generation which was initially released in 2014 for PlayStation Vita and Steam with slightly more content and a revamped combat system to fall more in line with Victory.
Hyperdimension Neptunia Victory (2012)
The third game in the series, in which Hyperdimension's Neptune finds herself crashing head first into an alternate dimension called the "Ultradimension" that is based around gaming culture around the early generations until the sixth-generation era of gaming, while returning to the series more comical tone.
It received an enhanced version for the PlayStation Vita and Steam as Hyperdimension Neptunia Re;Birth 3: V Generation which was initially released in 2014 with minimal changes to combat and added story scenes for postgame and an extended prologue taking place before Neptune's comical fall into the Ultradimension.
Megadimension Neptunia VII (2015)
The first game in the series for PlayStation 4 released worldwide in 2016. The game's plot is slightly inspired by the shift from the seventh generation of consoles to the 8th generation, as well as the history of the Sega Dreamcast.
The game received a remake, framed as a retelling of the True Ending route, in 2017 as Megadimension Neptunia VIIR which featured new cutscenes with VR support. Released on the same platforms as the original (except for the Nintendo Switch, which still received the original release).
Hyperspace Neptunia Unlimited (2026) The first new mainline game in eleven years, focusing on new CPUs based on the 9th generation consoles, with Neptune herself stuck in a time loop. The gameplay takes after Neptunia's shift to RPG-Action first introduced in Sisters vs. Sisters and a more open world/open zone style exploration with flight mechanics.
The game is set to release on PS4 (digital only), PS5, Switch, and Switch 2 in Japan by August 27, with a western release expected sometime in 2027.
Spin-offs Hyperdimension Neptunia: Producing Perfection (2013)
An idol-raising simulator game with rhythm and dating sim elements. It is the first game in the series to be on the PlayStation Vita and was the only game in the series to not receive a port to PCs. The game is deliberately non-canon.

Hyperdimension Neptunia U: Action Unleashed (2014)

Superdimension Neptune vs Sega Hard Girls (2015) Crossover RPG with the Sega Hard Girls franchise with an isolated narrative away from the main series starring IF-chan as the protagonist. The gameplay is inspired by those of the Re;Birth games.
Cyberdimension Neptunia: 4 Goddesses Online (2017)
Action RPG based on a fictional MMORPG within the series universe, in which all of the goddesses play in their freetime together. Although the game is called "online", it is a single player game with optional multiplayer missions, meaning no online requirement for its story content.
Neptunia & Friends (2017) Interaction/Card game released in Japan for Android and iOS. The localized version was released exclusively for iOS and featured less characters and updates compared to the Japanese version.
Nep-Nep★Connect: Chaos Champloo (2017) Free-to-play card battle game, and the first Neptunia game to not be released outside Japan. The game's support was terminated on August 8, 2018. Though it wasn't released outside Japan, the English version of Neptunia Virtual Stars gives this game the name "Nep-Nep★Connect: Chaos Champloo" when referring to characters that debuted in this game in its collectible card list.

It was ported to PlayStation 5 alongside Neptunia re★Verse.
Neptunia Virtual Stars (2020) A hack 'n' slash game with rhythm elements that tackles and parodies culture around social media, featuring various Vtubers. The first game in the series not to receive an English dub due to the amount of guest Vtubers present.
