The latest issue of Shonen Jump has confirmed that Shisui Uchiha will be a playable character in Naruto Shippuden: Ultimate Ninja Storm Revolution. In addition, it also states that the game will be available in Fall 2014 in Japan.
The game will feature Shisui's story, which will be told via anime-style cutscenes, similar to how the Akatsuki's backstory will be told. Since Shisui's battle skills were never shown in the manga or anime, Namco Bandai will have to create the character's moveset and abilities.
Naruto Shippuden: Ultimate Ninja Storm Revolution will contain team jutsus and over 100 playable characters. The game will be available in 2014 for Xbox 360 and PS3.
