About Hyperdimension Neptunia Re;Birth1

Hyperdimension Neptunia Re;Birth1 unfolds in the world of Gamindustri, a realm once shaped by the War of the Guardians, a conflict fought between four goddesses known as CPUs. One of these rulers, Neptune, was defeated by the others and cast down from the heavens, losing her memories in the fall. Her journey back begins when a mysterious book appears before her, holding within it the entire history of Gamindustri.

From there, Neptune sets out on a sweeping adventure to save the world, and she doesn't travel alone. She's joined by a memorable cast that includes Compa, IF, and Histoire, the sentient book that first revealed itself to her. Together they cross four different nations, each part of the larger struggle to restore balance to Gamindustri.

As an RPG with strategy elements on PC, the game frames its quest around this fall-from-grace premise, following Neptune from banishment and lost memory toward a mission that spans the whole world. The blend of a goddess protagonist, a distinctive supporting party, and a multi-nation journey gives the adventure its shape as players work to save Gamindustri from the fallout of the Guardians' war.
