Tekken 3 maintains the same core fighting system and concept as its predecessors, but brings many improvements, such as significantly more detailed graphics and animations, fifteen new characters added to the game's roster, more modern music and faster and more fluid gameplay.
Perhaps the most noticeable change from Tekken 2 fight system is movement reform - whereas the element of depth had been largely insignificant in previous Tekken games (aside from some characters having unique sidesteps and dodging maneuvers), Tekken 3 added emphasis on the third axis, allowing all characters to sidestep in or out of the background by lightly pressing the arcade stick (or tapping the controller button in the console version) towards the corresponding direction. Another big change in movement was that jumping was toned down, no longer allowing fighters to jump to extreme heights (as was present in previous games), but keeping leaps to reasonable, realistic heights. It made air combat more controllable, and put more use to sidestep dodges, as jumping no longer became a universal dodge move that was flying above all of the ground moves. Other than that, the improved engine allowed for quick recoveries from knock-downs, more escapes from tackles and stuns, better juggling (as many old moves had changed parameters, allowing them to connect in combo-situations, where they wouldn't connect in previous games) and extra newly-created combo throws.
