is a spin-off of Namco's Tekken fighting game series. It is the fourth installment in the Tekken fighting game series. Tekken Tag Tournament was released as an arcade game in 1999, before becoming a North American and European launch title for the PlayStation 2 in 2000. The arcade version operated similarly, but ran on a 32-bit graphics engine like Tekken 3. It received upgraded graphics when it was ported to the PlayStation 2. Its sequel Tekken Tag Tournament 2 was released in 2011. A remastered version of the game titled Tekken Tag Tournament HD was released for the PlayStation 3 in November 2011, as part of Tekken Hybrid. Gameplay Continuing the fighting mechanics from Tekken 2 and 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. The game features over 35 characters that previously appeared in Tekken 2 and Tekken 3. In addition, there is a boss character, Unknown, who is similar to Tekken 3's Mokujin in that she can randomly imitate any character's fighting style, albeit she is able to change her style any time during the fight. The PlayStation 2 version added enhanced graphics and various modes, including 1-on-1 mode, in which players only choose one fighter each, and Team Battle, where players choose up to eight battles and play with the tag rules, with each new character replacing the one that was defeated (the remaining fighter must fight on his/her own). Also featured is the "Tekken Bowl" mode, a bowling minigame where each character has different attributes. The arcade and console versions of Tekken Tag Tournament differ slightly. The arcade version ran on a 32-bit engine, utilizing the graphics engine of Tekken 3. These graphics ran
