As the game's popularity grew, so did the demand for new and exciting content. In response, Namco Bandai Games, the game's developer, announced that they would be releasing a series of DLC (downloadable content) characters for the game.
Gamers went wild with excitement as they speculated about who the fourth character could be. Some thought it would be a classic Tekken character making a comeback, while others believed it would be a brand new fighter.
The success of the DLC characters for Tekken Tag Tournament 2 paved the way for future games in the series, including Tekken 7, which was released in 2015. The game's DLC character model has also been adopted by other fighting game developers, and it continues to be a popular way for gamers to add new content to their favorite games.
