Its GDC week in the world that is the video game industry and new trailers are rolling out like crazy. Here we got the clip for Dead or Alive 5 featuring Ayane and Kasumi duking it out, but that's not all. The big reveal is a special cameo appearance by Akira from Sega's Virtua Fighter franchise. It is not as weird as a crossover as you think because this one actually makes sense since DOA and VF have been reputable 3D fighting game franchises throughout the genre's lifespan. Akira makes the transition to DOA well with his signature VF moves and style intact. Team Ninja has teased some weeks back that a Dead or Alive vs. Virtua Fighter game is a possibility and this looks like a start towards making that a reality, but who knows if Sega is down as well to make it happen. Also in this clip, the fighters do take cosmetic damage, so you'll see parts of clothing wear off or get dirty as seen in Tekken Tag 2 and Mortal Kombat. Dead or Alive 5 is slated to come out this fall on PS3 and 360 as we'll see if Team Ninja has more surprises like this ahead in the coming months.
