In the first Dead or Alive, stages were simply fighting ring arenas and the Danger Zones were just explosive outer edges of the arena floors. In Dead or Alive 2, stage environments became larger and multi-tiered and the original Danger Zone was replaced with more fully interactive ones such as Falls off the Edge, Walls, Electrically Charged Walls, Explosive Walls, Breakable Walls and Windows. Players are also offered the ability to sidestep into the foreground or background.
