The game is set immediately after the tournament in Dead or Alive 3 ended. Gameplay revolves around the women of the DOA series playing various mini-games in the many locations of Zack Island, a reclusive private resort on an island owned by Zack, the only male character from the series to appear anywhere in the game. This installment features no fighting engine, instead being much like a simulation game that encourages the player to establish relationships with the AI of characters, and eventually make a two-person team to compete in volleyball competitions. Currency earned from completing mini-games and gambling in the island's casino allows the player to purchase hundreds of different swimsuits to wear in the game. In the main story mode, players select a woman to play as for the duration of their two-week period. Since the volleyball matches in the game are always two on two, the player automatically begins with a partner. Each day, players can select one activity in the morning, one in the afternoon, and one in the evening. While players do have an opportunity to simply relax during these time periods, they are generally used to either court new partners, or to challenge existing partnerships to a game of volleyball. Winning a match provides money which can be used to buy swimsuits and accessories, either for oneself, or as gifts to bestow upon the other women. Alternatively, players can also earn money through gambling at a casino located on the island.
