All 26 characters in Dead or Alive 6 will be playable February 15th and 16th during EVO Japan 2019 at the Fukuoka International Center! There will not only be a demo of the latest build, but streamed exhibition matches with 4 skilled players to better showcase the mechanics. Team NINJA's Yohei Shimbori will also be giving a presentation with new information pertaining to DOA6.
Siologica and Teru Rock will be making special appearances at the EVO exhibition. They are both accomplished fighters with offline tournament wins and should be able to offer plenty of information in their matches. There should be opportunities for players to see if adjustments have been made to the current system like the ground game, which has been seen by many as incomplete at this point in time.
You can peruse the event information at the Japanese DOA6 Official Website, and you can expect an update here at Free Step Dodge when the stream schedule is announced. Hopefully a road map for offline tournaments is announced by Team NINJA at EVO Japan since DOA6 comes out March 1st and nothing has been confirmed yet.
