Tekken 5 is a fighting game developed and published by Namco for the arcades in 2004, and for the PlayStation 2 in 2005. It is the fifth main and sixth installment, in the Tekken series, marking the tenth anniversary of the series. The game is set shortly after the events of Tekken 4 showing a new person named Jinpachi taking over the zaibatsu special forces while a sidestory focuses on the protagonist Jin Kazama as he faces several enemies from the G Corporation. The game removes several major gameplay changes introduced in Tekken 4, such as uneven stage terrain, in favor of a faster gameplay akin to the older games in the series. It is also the first game in the series to feature the ability to customize characters with accessories, clothing, and other aesthetic items purchased with in-game currency. There are up to 32 characters to choose from, including seven new fighters, as well as Jin's alter-ego Devil Jin. The home version includes a mode known as Devil Within, a variant of Tekken Force introduced in Tekken 3. The game was upgraded to Tekken 5.1, which had mostly balance changes to the gameplay, and later received the update Tekken 5: Dark Resurrection which was released in 2005 and later ported to the PlayStation Portable and the PlayStation 3 as Tekken: Dark Resurrection. Tekken 5 was a critical and commercial success, selling over 8.2 million copies including expansion. Critics praised the return of classic gameplay features and the large amount of replay value provided by the PlayStation 2 port though the final boss was criticized for being too powerful while Jin's story mode was felt boring in comparison to the fighting game part. A sequel titled Tekken 6 was released in 2007.
