I am not a big fan of cross overs, but for fighting games it is highly acceptable. In Dead or Alive 4, for the Xbox 360, we will be seeing someone from Halo as one of the fighters. No one knows which character from Halo will be featured yet, but I don’t really think it matters. Any of them would be fun to use.
Joystiq has the details:
We brought you news earlier today of a rumored crossover appearance of a character (or thing) from Halo making it into Dead or Alive 4 for the Xbox 360. Now we hear that Bungie’s confirmed the cameo, but won’t say who will be fighting against Kasumi and crew.
