Well, this is a new experience. Compile Heart has debuted 10 minutes of footage taken from the next entry in the Hyperdimension Neptunia series, VVVTunia - which is headed west on PS4 as Neptunia Virtual Stars in 2021.
The novel twist here is that the VVVTunia is itself being played by two more virtual characters. Upd8's Hibiki Ao is controlling out the action, while being hosted and cheered on by "virtual YouTuber" Ilheart. While I wrap my old man head around this meta-beyond-meta concept, check out the gameplay footage the video below, courtesy of... Ilheart... I guess?
Gameplay begins at 05:28. Be warned, the first 20 seconds of this video are pretty intense.
