The Dead or Alive franchise is infamous for its efforts to oversexualize its female fighters. That reputation has been helped along by the Dead or Alive: Xtreme spin-offs, a collection of titles that put all the women in skimpy bikinis as they play beach volleyball and seaside party games. The main series has also been difficult for newcomers to jump into, as each game lacks the type of single-player campaign that would help a beginner acquaint themselves with the combo-heavy system of strikes, holds, and throws.

Team Ninja's last entry in the franchise, Dead or Alive 5, did make an initial effort to broaden its audience by choosing to clothe the fighters in slightly more modest attire and write in a science-fiction story. However, the game still launched with the franchise's well-known mechanic of choosing your preferred levels of "boob jiggle physics," and DLC expansions brought many of the series' racy and fetishized outfits back into the game. The story mode also expected a certain level of skill from players, and since the tutorial system was a grind-fest of memorizing button combos, it was still difficult to learn the nuances of the game.
