Nintendo has posted a video showing off Kasumi in action. Her gameplay in Ninja Gaiden 3 Razor Edge is a lot like her gameplay in Dead or Alive. She teleports around a lot and has a laser like ninpo. If you want a look here you are. http://www.youtube.com/watch?feature=player_embedded&v=UOjXBhD12fA#!
As always thank you for reading.
