Shin Megami Tensei: Persona 4, known in Japan as Persona 4 (ペルソナ4, Perusona 4), is a console role-playing game developed and published by Atlus for Sony's PlayStation 2, and chronologically the sixth installment in the Persona series. Persona 4 was released in Japan on July 10, 2008, was released in Korea on October 31, 2008, in North America on December 9, 2008 and will be released in Europe in Spring 2009. Instead of the city locales of previous games in the series, Persona 4 takes place in a fictional Japanese countryside. It features a weather forecast system with events happening on foggy days to replace the moon phase system (with events happening on full moons in Persona 3) implemented in the previous games. Its story is a suspenseful countryside murder mystery with multiple twists and turns in the plot. The North American package of the game was released with a "Visual Data" book (a collection of concept art) and a CD with selected music from the game, very much like Persona 3's North American release.
