Persona 4, also known as Shin Megami Tensei: Persona 4, is a role-playing video game developed and published by Atlus for the PlayStation 2. It is chronologically the fifth installment in the Persona series, itself a part of the larger Megami Tensei franchise, and was released in Japan in July 2008, North America in December 2008, and Europe in March 2009. Persona 4 takes place in a fictional Japanese countryside and is indirectly related to earlier Persona games. The player-named protagonist is a high-school student who moved into the countryside from the city for a year. During his year-long stay, he becomes involved in investigating mysterious murders while harnessing the power of summoning Persona. The game features a weather forecast system with events happening on foggy days to replace the moon phase system implemented in the previous games.
