Hey, people! Since it was requested by several people that I do this, here it is.

The above is the link to the system data for Dead or Alive 5 game for XBOX360. It contains 100% completion for Titles, Story mode has been completed, all characters are unlocked, and all costumes are available.
However, you cannot just download the save and carry it over to your gaming profile. The save needs to be reassigned first, and you can use a couple of programs for that. I'd recommend Horizon. If you don't know what Horizon is or how reassigning the save is done, google it - you'll find plenty of tutorials.
