Tekken 4 is a fighting game in the popular Tekken series that was released for PlayStation 2 and other platforms back in 2001 by Namco (now known as Bandai-Namco Entertainment). The fourth main installment in the critically acclaimed franchise, it brought several new features to the table while maintaining many of the core elements fans had come to love.

In terms of gameplay, Tekken 4 introduced a number of changes designed to enhance player experience. One notable addition was the 'rage system,' which allowed characters to enter an enhanced state known as 'Rage' when their health bar fell below certain levels. While in this mode, players could perform devastating combos and special moves with increased power and speed.

Another significant change introduced by Teken 4 was the inclusion of a new character named Anna Williams - younger sister of Nina and older twin sibling to no less than two other female protagonists from different fighting series: 'Fatal Fury' (or simply 'Fatal') franchise where her identical lookalike appears alongside as well!
