What a great idea. If you missed Persona 4 Arena and are planning to start out with its upcoming sequel, Persona 4 Arena Ultimax, you may be pleased to hear that Arc System Works has prepared a special Premium Newcomer Package DLC that will contain the story of the first game.
Siliconera reports that other included goodies were revealed in the latest Famitsu piece on the game. A glasses set for all characters, an additional 12-song music track set, and a Navigator tryout set (Teddie and Mitsuru) are also to be included. The date and price have not been set, and we're assuming that this is a Japan-only thing for now.
