BlazBlue: Cross Tag Battle already features a couple characters from RWBY in its 20-character roster, but Arc System Works will be adding at least one more as DLC. The first downloadable character has been revealed as Blake Belladonna, and we officially have a launch date to go along with the announcement.
BlazBlue: Cross Tag Battle hits PS4, Switch, and PC in Japan first on May 31, followed by North America on June 5. In addition to the 20 base characters, Arc has 20 more planned as DLC. You can see Blake Belladonna's reveal in the new trailer below.
