Dead or Alive Xtreme Beach Volleyball(DOAX) is a self-proclaimed Sports Fantasy Game that uses characters from the Dead or Alive series. Set upon an island owned by Zach (Voiced by Dennis Rodman), players choose one of the lovely female fighters and compete with a partner in volleyball games. Although it is a volleyball game, the real main point of the game is the sexual aspect of the girls in swimsuits.
Using the prize winnings that he got from the DOA3 tournament, Zach went to Las Vegas to blow his money on a Vegas Vacation. However, a lucky stroke landed him major winnings, which Zach then used to purchase an island in the south seas, which he named after himself. He set up facilities on the island and invited the female characters from the DOA series there, under the guise of hosting the DOA4 tournament.
