Koei Tecmo still has a couple of months before Dead or Alive 6 drops, but today Team Ninja is doing a beta online test starting today. It will last until January 14th at 10 am EST.
The beta will have five characters and an online versus mode. Again this will be an online stress test for Koei. If you have a PS4 with Playstation plus, you can download it here. Unfortunately, the PS4 is the only system that will contain the beta.
