"Tekken 3" introduced several gameplay possibilities that were retained in later games, including the ability to sidestep into the foreground or background. "Tekken 3" and later games also reduced recovery time after being knocked down and gave characters rolls to recover instantly after hitting the ground, allowing the player to get back into the fight more quickly at the risk of being hit while rolling. "Tekken 4" gave characters even greater mobility by adding true 3D movement inside geometrically complex arenas with uneven ground, obstacles, and walls. The 3D gameplay allows damaging side and back throws as a reward for outmaneuvering the opponent, as well as evasive attacks that develop directly from a sidestep.
