The Tekken Tag Tournament 2 uses the Octave graphics engine. One of its characteristic features is the most realistic rendering of natural elements such as water and sand, which react according to the characters' movements in space. Additionally, it is noteworthy that due to the nature of the fights, there are moments where all four characters appear simultaneously without a drop in frame rate.

A new player also makes her appearance, JayCee, although her moves and initials (JC) are reminiscent of Julia Chang. Finally, Heihachi Mishima is here but with a small change. He is now younger, the result of genetic experiments performed on his body. In conclusion, we are talking about over 40 players available in the roster.
