According to a special edition book handed out to fans (thanks VG247), Final Fantasy XV's season pass will feature four big content pieces: a story expansion about each of the key people in the game, and a multiplayer DLC.
The first DLC pack is called Episode Gladiolus, where Gladiolus battles against Gilgamesh. Final Fantasy XV's season pass in now available for PS4 and Xbox One if you want to grab it before this releases, though, as this will get you all the DLC packs and a few extra bits and pieces. Which character will have the best DLC pack?
