On April 19, 2007, Atlus released an add-on disk for Shin Megami Tensei: Persona 3 called Persona 3 FES (ペルソナ3フェス, Perusona 3 Fesu).

A "director's cut" version, which included both Persona 3 and Persona 3 FES, was released on the same date. The subtitle of "FES" is said to come from the word "festival."

FES, in addition to adding a great deal of content (both gameplay-related and storyline-related) to the main game, includes a continuation of the story entitled Episode Aegis.

When beginning the game, the player is prompted to select Episode Yourself or the aforementioned Episode Aegis. Episode Yourself is the original game with added content, whereas Episode Aegis can be considered a sequel, featuring Aegis as the main character.

The North American release of Persona 3 did not include the content from FES, although Atlus has not ruled out the possibility of releasing FES there at a later date.
