Although only a handful of the characters to be featured in Dead or Alive 5 have been confirmed by Tecmo, the enterprising users of the Neogaf forums
) have discovered what appears to be the game's complete roster by peering into the bytes of the demo executable -- presumably via a modified Xbox 360 console.
***Spoilers*** The list reportedly includes everyone from Dead or Alive 4 with two newbies as well as three familiar fighters from SEGA's Virtua Fighter series: Pai, Sarah, Akira, Mila, Rig, Bayman, Hitomi, Christie, Brad, Lisa, Eliot, Ayane, Leifang, Hayate, Kokoro, Bass, Leon, Helena, Genfu, Kasumi, Hayabusa, Jannlee, Tina, Zack, Alpha152 ***Spoilers***
The files are also said to indicate that each fighter will have six assorted costumes. Of course all of this is subject to change with the final release of the game, but at this late stage of development it's probably more likely than not.
Dead or Alive 5 is due on Xbox 360 and PlayStation 3 in September 2012.
