While there isn’t a full-fledged Hyperdimension Neptunia fighting game (yet?), Hyperdimension Neptunia U: Action Unleashed has a mode where the CPUs can battle each other. All 18 playable characters can brawl in the Gamindustri Gauntlet. Win matches and you can earn special accessories for your characters.
This mode is a return to Tamsoft’s roots. While they’re known for Senran Kagura and the Onechanbara games these days, Tamsoft was the developer behind Battle Arena Toshinden, an early PsOne fighting game that Sony touted as one of their key launch titles.
Hyperdimension Neptunia U: Action Unleashed comes out for PlayStation Vita this spring.
