Tecmo Koei just released a video which shows off some gameplay from the demo of Dead or Alive 5. It's a little under two minutes of boobs, brawls, and exploding trains, as you might expect, but it's rather impressive.
The demo shown below is the girl's demo, available if you pre-order Ninja Gaiden 3 Collector's Edition at GameStop. Dead or Alive 5 is set to drop sometime in September. Check out the demo trailer for yourself after the cut.
