Play as the bosses :
Exactly as in the original Tekken, you must firstly beat all of the other fighters (including the bosses) before the sub-bosses are added.
After enabling all characters, hold select while choosing your character until battle begins. Et voila - instant hydroencephalitis. Finish a fight and hold select again (with the same character), and you're a Pep-Boy.
Wire Frame Mode:
For First Person Perspective - after enabling all characters, select 1-player mode, hold L1 while you choose your character, and you become a wire-frame. For Second Person Perspective, enter practice mode, and hold L1 until the match begins, and your opponent becomes a wire-frame.
Kazuya's Purple Suit:
Choose Kazuya and hold down Start before the Vs. screen appears. Check out the nifty purple suit.
Super Juggle Mode:
Select a player and hold Select & Up until fight starts . You should hear a punch sound.
You have to be in 1 player mode. Then let the opponent of the third match beat up on you until you have a little life left (5%). Crush the opponent and the announcer will say "GREAT!" You do this two bouts in a row and the next fight should be against Roger/Alex. Beat them and play through the game. Roger/Alex should be selectable.
To make your character swear in Japanese press Right, Left, Square, and Circle at the end of the fight!
