A Persona fighting game? It's really happening, thanks to the people at Atlus and BlazBlue creators Arc System Works. This is what it looks like — lovely! — and this is who will be beating each other up in Persona 4 The Ultimate in Mayonaka Arena.
The Persona fighting game, coming first to arcades later this year, then to consoles, will pit characters from Persona 3 and Persona 4 in mortal combat, known as the "P-1 Grand Prix" in-game. See first screen shots below, with additional character art at Famitsu.
