THE KING OF IRON FIST TOURNAMENT

Tekken ( Iron Fist) is a series of fighting games developed and published by Namco. Originally an arcade game, versions exist for the PlayStation, PlayStation 2, PlayStation Portable, PlayStation 3, Xbox 360, Wonder Swan, and Game Boy Advance. The story in each game in the series (with the exception of the non-canon game Tekken Tag Tournament) documents the events of the fictional martial arts tournament, The King of Iron Fist Tournament, with the game's chronological number corresponding with the current iteration of the tournament.
The tournament is always hosted by a financial corporation called the "Mishima Zaibatsu", with the tournament prize generally being control of the company offered to the victor (who then is free to host the next King of Iron Fist tournament). The arcade versions are known to traditionally use PlayStation based hardware for each installment, and subsequently each arcade version was eventually made for its respective PlayStation.
There are currently six main installments in the Tekken series. In May 2010, Namco Bandai announced that a seventh game had been given the go ahead, although no further details have, as of yet, been confirmed.
