King: Easier chain-link combos:  "Buffering" is an extremely useful technique for pulling off some of his ridiculously difficult chain-link combos. This technique is done by holding down a button(s) in the current button combination if that same button(s) is used in the next combination while pressing any additional required buttons in the next combination. For example, if one of the combos requires you to press Square + X, then X + Circle, to "buffer" this combo press Square + X, then while holding X, press Circle. Also keep in mind you can buffer multiple buttons. It seems very complicated but it is much easier than it sounds and makes things incredibly easier. Try studying all of kings chain-link combos and you will notice you can "buffer" almost all of them at a certain point in many different ways. Another helpful hint is to program the four shoulder buttons with different button combos such as LP + RP, LK + RK, LP + LK, and RP + RK. You will notice that these combinations are the basis of almost all of his combos.

Law: Partner attack:  When playing as Law have Lei or Howrang as your partner. When you are Law, press Forward, Triangle, Square and press Tag as soon as possible. Lei or Howrang will automatically run and do a Flying Drop Kick.

Law and Paul: Special attack:  As Law, press Forward, Triangle, Square followed quickly with Tag. When Paul enters, press Triangle(2). Paul will hit the enemy in the air and automatically tag out. When Law enters, press Square to hit the falling enemy.

Paul: Easy win:  Use a move that makes them go flying, then use the Burning Fist attack when they get up.

Yoshimitsu: Easy win:  Use his Sword Stab attack.

Unknown: Cycle through stances:  When playing as Unknown, press R3 to cycle through stances.

Xiaoyu: Looking around:  Press Circle + X + Square while fighting as Xiaoyu.

Yosimitsu: Easy win:  Press Triangle, Circle(2). Do this repeatedly to win.

While in battle, use the Spin Kick with X. When your opponent is about to get up, press Away(2), Square This will take a lot of their health down. Then, attempt the same thing before he or she can switch out.

99 hit combo in practice:  Go to practice, highlight and select Yoshimitsu with Triangle, Hwarong with Square (for you); then Eddy Gordo with X, and Paul Phoenix with X as your enemies. When you go in you can pull off any hit combos, make sure your opponents do not fall over. If they do, the hit combo will stop counting and start over.

Faster character unlock:  Go to the Player 1 versus Player 2 mode, and keep fighting with different characters. After awhile, characters will start unlocking. Keep doing this until every locked character is unlocked, then save the game. In order to leave this mode without losing all the characters, you have to exit during battle by pressing Start and exiting to the main menu. Then, go to options and save.

Go to team battle mode and select eight characters (Yoshimitsu, Paul, Gun Jack suggested, as well as any character that has an ultimate move which takes off about 75% of opponents health). Press Start on controller two and do the same. Start the battle. Do an ultimate move (for example, Back, Back + Square with Yoshimitsu, or Back + Square + Triangle with Paul). When you unlock Wang and Roger, choose them for both players, as their moves are also quite strong. Every second time you do all of this, you will unlock another character. This takes about five minutes each time Note: You must exit from a battle and save the game. If you exit from the character selection screen or just save directly from the menu, any unlocked characters will be lost.

Fight longer and better:  During a match against the CPU, try to keep some distance between you and your opponent. This gives the CPU opponent less chances to grapple and slam you to the ground. Keep a good distance and block as often as possible. Attack when you get the chance and get out of there as soon as possible. You may still lose but if you practice this technique you will win. Your battles will last a little longer so you may want to set the timer to infinite.

Defeating Unknown:  Choose any character, and select Eddy, Bruce, Paul, Law or anyone who can do major damage or are quick such as Eddy or Jun as your second character.

Jack 2 appearance:  Look closely in the background. You can find Jack 2 on the left screen from the helicopter (90 degrees to the left). He will repeat going around. Even when the same costume is on Jack 2, he will still look the same.
