Team Ninja has released additional information about the mechanics of cross-play for Dead or Alive 5 – AKA PS3/Vita matchup in Dead or Alive 5. You’ll be able to see via an icon whether your opponent is playing on Vita or PS3, a distinction that will also be shown in rankings.
Team Ninja also promises 60 frames per second in cross-platform matches, on both platforms. And your saves will work across platforms, like other Cross-Save games, so there’s really nothing stopping you from maintaining your lifestyle of playing Dead or Alive 5 absolutely all the time.
