Dead or Alive Paradise , all the way through until the release of Dead or Alive 6 in 2019. In a statement on Twitter, Shimbori didn’t state whether he would remain in game development now that he has left Koei Tecmo: As of today, I have left Koei Tecmo Games. I worked on Dead or Alive for 16 years, and while there were times I was pleased, there were also times I was unable to live up to expectations. I would like to take this opportunity to express my utmost gratitude to the many people who have supported and taken care of me. Thank you very much.
