Persona 5 DLC, with full English voice over by the original cast, has been announced for Catherine: Full Body.
During the Catherine: Full Body Experience and E3 Celebration, a brand new trailer was shown, showcasing the Joker + Phantom Thieves DLC. It looks to be the same DLC the Japanese version of Catherine: Full Body got last year, which allowed you to play as Joker in the Babel and Coliseum modes with commentary by the Phantom Thieves, and included some music from the notoriously amazing sound track. If you play Catherine: Full Body, you may hear some similarities – both it and Persona 5 have music composed by Shoji Meguro.
Catch a look at Joker in action in a level from the Japanese version of Catherine: Full Body above.
