Tekken (Japanese: 鉄拳?, “Iron Fist”) is a fighting video game franchise created, developed, and published by Namco (later Bandai Namco Entertainment). Beginning with the original Tekken in December 1994, the series has received several sequels as well as updates and spin-off titles. Tekken was one of the first fighting games at the time to use 3D animation. The series has also been adapted into three films and other media. The series’ official English name is always written in all-capital letters (TEKKEN, abbreviated to TK). There are six main installments to the series, one installment having an updated version that also made a home release, two non-canonical installments, and a seventh mainline game in the works.
The premise of each game in the main series documents the events of the King of Iron Fist Tournament, hosted by the Mishima Zaibatsu corporation. The prize is typically control of the company, which then allows the winner to host the following tournament. After beating the game with each character, an ending cutscene is unlocked and usually one of the endings from each game becomes the continuation of the story into the following installment. The story has largely revolved around the Mishima clan curse, which began narratively with Heihachi Mishima throwing his son Kazuya Mishima from a cliff when he was 5 years old. Kazuya was nearly killed from the fall, but through the influence of the “Devil Gene” he survived and swore revenge to his father by the time of the King of Iron Fist Tournament.
The second game and its sequel were considered breakthrough titles and among the greatest games of all time, the latter also being the second best selling fighting game to date. The series itself is the best selling fighting game franchise in history.
