Butt Battle

Butt Battle, also dubbed as Hip Battle, is a pool game in Dead or Alive Xtreme 2 and Dead or Alive Paradise. Playable only at the poolside, the game challenges the player to knock their opponent off a floating pad using their character's backside before the same can be done to them.

Dead or Alive Xtreme 2
Using the left analog stick, gameplay involves feigns, dodges, normal attacks and strong attacks, which the girls carry out using only their rear-ends. It is played in a similar fashion to "Rock, Paper, Scissors", in which one must correctly guess or deduce the opponent's next action and respond appropriately.

Dead or Alive Paradise
Butt Battle is an unlockable game in Paradise; the player must accumulate a total of 100 "Venus Clips" in order to unlock it. Gameplay is simular to that in Xtreme 2, instead the D-pad is used instead of the analog stick.
