New Mainline Hyperdimension Neptunia Game Announced After 10-Year Absence

Ten years is a long time to wait for a mainline entry in any JRPG series, and Neptunia fans have been living that reality since Megadimension Neptunia VII. Idea Factory and Compile Heart ended that drought via a special livestream on the Compile Heart Official YouTube Channel, revealing a new title carrying the tentative English name Neptunia: Unlimited (Japanese: 超新時空ゲイム ネプテューヌ∞). The official English title is still to be announced.

The game is scheduled to launch in Japan on August 27, 2026, across Nintendo Switch, Nintendo Switch 2, PlayStation 5, and PlayStation 4. Worth flagging for physical collectors: the PS4 version will be digital-only. Standard pricing is set at 8,580 yen, while a limited edition runs 19,800 yen and bundles in a copy of the game, a special box featuring packaging illustration by series artist Tsunako, a premium art book, a soundtrack CD, the Season Pass, and a Divine Cross promotional card.

The biggest mechanical departure from past entries is a combat system built entirely around flight. Aerial battles and mid-air gimmicks form the backbone of the gameplay rather than functioning as a secondary layer on top of traditional ground combat. The headline set-piece mode, described by Automaton West as "Apocalypse Battle" (flagged as an unofficial translation), throws all of the goddesses together against a single colossal Apocalypse Boss. The counterplay mechanic in those fights involves Apocalypse Counter Skills, which Automaton West describes this way: "By skillfully utilizing Apocalypse Counter Skills, you'll be able to block the hard-hitting special attacks expelled by the boss, and use that power to strike back."

The story kicks off with what the official site calls "the first meteorite that signaled the end of the world." Neptune finds herself alone in a white space after the catastrophic impact, guided by an unknown voice and marked with a strange number. She gains a "Retry" ability that lets her loop between endings and new beginnings, and as she progresses she reunites with allies while encountering new companions and enemies in an attempt to overcome repeated failures.

On the character front, the four classic goddesses return: Neptune (Purple Heart), Noire (Black Heart), Blanc (White Heart), and Vert (Green Heart). Joining them are three new figures. Rouge transforms into Red Heart and is filling in as Goddess of Lowee while Blanc pursues a new gig as an anime creator, a role that opened up after her novel was picked for adaptation. Ciel becomes Blue Heart and takes over Lastation; she appears to be modeled after the PlayStation 5 and even sports an Astrobot-inspired catbot on her arm, while Noire operates in the shadows nearby performing heroic duties out of the spotlight. Rounding out the new cast is the duo Anna and Lot, who share the Eclipse Heart transformed state. Compile Heart describes the new roster broadly as four brand-new goddesses inspired by current game hardware, and Tsunako is back designing the new costumes alongside her packaging illustration duties for the limited edition box.

NoisyPixel also flagged a separately announced anniversary insert song titled "Invincible Bonds -Re:boot & Update-" tied to the game's reveal, suggesting the promotional rollout extends beyond the core gameplay trailer.

No English localization date or Western release window has been confirmed. Compile Heart has stated the official English title will be announced at a later date, and several outlets covering the announcement explicitly noted there are currently no details on a release outside Japan.
