Persona Q 2, the second game in the series of Persona crossovers based around Etrian Odyssey's mechanics, is coming out in Japan later this year. While the previous game brought together the casts of Persona 3 and 4, the sequel adds Persona 5 into the mix for a cinema-themed story. You can check out the intro video below.
The intro also shows a few of the original characters in the game, much like Persona Q had.
While Persona Q 2 has not yet been announced for America, Atlus has never shied away from releasing a game on aging systems, especially for more fan-oriented titles. The Japanese version of the game launches in November on 3DS.
