Tekken Ball is the Tekken 3 bonus mode that returns in the Wii U version of Tekken Tag Tournament 2.
Tekken Ball is a beach-volleyball-style fighting minigame in which characters strike a ball toward one another. Attacks charge the ball with damage, so a successful return can hurt the opponent when it lands. The mode first appeared in Tekken 3 and became one of that game’s most memorable extras.
The Wii U Edition of Tekken Tag Tournament 2 brought the minigame back as part of its exclusive content. That version also added Nintendo-themed costumes, touch-based GamePad controls and Mushroom Battle, which uses power-ups inspired by Super Mario. These additions made the Wii U release more than a straightforward port.
Tekken Ball should not be confused with Scenario Campaign, Devil Within or Tekken Force. Those are action-oriented modes associated with other Tekken entries. Tekken Tag Tournament 2 itself is a tag-team spin-off, while its Wii U edition was also a launch-window title for Nintendo’s console in 2012.
