The "definitive Dead or Alive 5 package" will add new modes from Dead or Alive+ such as the Skill Info Plus and a tutorial mode, and will include new fighting stages such as locations from the Ninja Gaiden series. The new game will have new fighters, including Jacky, Ein, and the first-ever appearance of Momiji. The new version will also have both a single-player mode and an online mode.
