Tekken Tag Tournament is a 1999 fighting game developed and published by Namco for arcades. It is a spin-off the Tekken series. Not canon to the main storyline, Tekken Tag Tournament features nearly all the characters in the previous Tekken games and introduces a two-on-two 'tag team' battle mechanic. It was released as an arcade game, before becoming a North American and European launch title for the PlayStation 2 in 2000. The arcade version ran on the same Namco System 12 board with a 32-bit engine as Tekken 3, while the ported home console version received upgraded graphics.
