Remake
Dead or Alive Ultimate is a remake of DOA and DOA2 for the Xbox with a greatly improved graphics engine. As it was created after Dead or Alive 3, it takes elements and mechanics from both its original iteration and successor. The action of 3D-axis movement is as free-formatted as DOA3, and Hitomi, as well as Gohyakumine Bankotsu-bo are now playable characters (albeit outside story mode), but other elements have been kept intact from DOA2. The biggest set of changes instituted in Dead or Alive Ultimate are online play over Xbox Live and the inclusion of slopes, which are a type of environmental hazard.
