During the Dengeki Game Fes 2018 livestream, Compile Heart made a surprising announcement regarding their flagship Neptunia series. A new game, tentatively titled Brave Neptune, is in development at Artisan Studios located in Quebec, Canada. You can find the debut video below.
Details on this new title are slim, and we do not have a release window or release platforms. More information is set to be revealed in the April 26th issue of Dengeki PlayStation. Some quick glimpses of gameplay in the footage seem to indicate that the game is a sidescrolling / 2D title [at around the 2:00 mark of the video.]
Artisan Studios' website originally showed platforms logos indicating a release for Nintendo Switch, PlayStation 4, Xbox One, and Steam, but the logos have since been removed.
