Hints & Tips

Steve Fox: Easy win
Simply use the Rocket Launcher (press Toward(2x's), Square).

Yoshimitsu: Secret taunts
Get yourself in the Meditating Healing (Down + X + Circle), into the Levitation (X + Circle), then release the buttons before you press Punch. Release Square to laugh, Triangle to say something, or Square + Triangle to says something.

Combot: Metal sound
Simply hold Down before any round starts to give Combot a metal sound.

Paul: Combo
Paul has two moves that make a good way to win. First, do the Hammer Of The Gods (Left + Up + Square + Triangle). As your opponent is getting up, then press Right + Up + Square + Triangle. This will take away 75% of your opponent's health.

Paul: Secret taunt
Simply crouch down without moving and wait for three seconds. Then paul will perform his Taunt Stands.

Jumping, ducking, blocking, and sidestepping
When your opponent does attack you with a low blow, like a sweep kick, jump and attack. Not only will you dodge your opponents attack, but you will have kicked his face into the dirt. When you opponent attacks you with an attack at your body, duck and attack. With any mid-attack, you should block in most cases or use a side step.

Wall-less stage
Play one game in time attack mode as any character. In the next game, play in story mode with the same character. When you get to Heihachi at the Arena stage, there will be no walls.

Yoshimitsu: Strong attack
Simply press Away(2x's), Circle to execute a stab that takes out plenty of your opponent's health.

Off the wall attack
Stand close to a wall with your back to it and tap Back(2x's), Up/Back. Your character will now jump off the wall and attack. This will work well in Tekken Force mode.
