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 fifth installment in the Persona series. Persona 4 was released in Japan in July 2008, North America in December 2008, and Europe in March 2009. Instead of the city locales of previous games in the series, Persona 4 takes place in a fictional Japanese countryside and is indirectly related to Persona 3. 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.
