As we previously reported, Arc System Works is collaborating with Koei Tecmo for a Guilty Gear and BlazBlue X Dead or Alive costume pack. In March, this DLC will be purchasable to those who own Dead or Alive 5: Last Round and available to holders of the season pass.
The promotional Japanese image lists the release date as March 14th. Altogether, there’s going to be 16 different costumes from -REVELATOR-, REV 2, and Central Fiction. So far, there are four promotional images as teasers. In the gallery below, you can see Kasumi as Noel Vermillion, Hitomi dressed as Tsubaki Yayoi, Nyotengu sporting Dizzy’s outfit and wings, and Honoka as Elphelt Valentine.
