In an update to their previous rating of Superdimension Neptune VS Sega Hard Girls for the PlayStation Vita, the ESRB has added a Windows PC platform.
The rating remains at T for Teen for, “Fantasy Violence, Language, Suggestive Themes” but now you can expect the game to launch on Steam as well. The Neptune games have begun to make their way to Steam, with Megadimension Neptunia VII, Hyperdimension Neptunia U: Action Unleashed, and Hyperdevotion Noire: Goddess Black Heart having already launched on that platform.
Currently Superdimension Neptune VS Sega Hard Girls is set for release in Fall 2016. It was released in Japan on November 26, 2015.
