Here's a screenshot gallery of the recent Dead or Alive 6 KO Ending featuring the stunning Dragon Shrine Maiden, Momiji. As I mentioned in the comments section of that post, I've finally decided on a new method for doing DOA6 KO Endings, which solves the problem of the game's often iffy KO faces. FYI, I previously used a function in Cheat Engine to select a specific KO face (the best one) for poses, though unfortunately by default the KO faces always seemed slightly pained as opposed to the more natural-looking neutral expression of unconsciousness- the worst example being Helena's.
I recently found a solution, though this involves actually freezing the whole scene, which is a compromise but I think in the end better-looking KO faces are more important than incidental animations. This will result hopefully in more and better KOs from DOA6 moving forward. For now, enjoy screens of unconscious Momiji!
