Tekken Tag Tournament is a spin-off of the Namco's Tekken fighting game series.

Continuing the fighting mechanics from Tekken 3, Tekken Tag Tournament sees players battling in teams of two characters. At any point in the match, the player can hit a tag button to swap out with their other fighter, allowing the resting fighter to recover some lost health. The tag can be implemented in many ways, such as in between combos or utilizing special throws. At times when a resting fighter's lifebar is flashing, that character can be tagged in to be given a temporary boost in strength. Unlike other tag games such as Capcom's Vs. series, players are defeated when only one of their fighters lose all of their health, requiring players to be strategic about tagging their fighters. In the event of a timeout, the team with the most accumulative health remaining wins the round.
