**Secret Characters**
  -Just beat the game in Arcade mode with any character and receive a new character. 
 
 **Tekken Ball Mode and GON** 
 -After you get the arcade hidden characters you can access Tekken Ball Mode. 
 Your first opponent will be GON. Beat him and you will be able to use him.  
 
 **Movie Mode** 
 -Beat the game with every character, (except Dr.B) and you will get a movie mode. 
 Now you can watch every ending without fighting, and pop in your tekken 2 cd 
 to see those movies too.  
 
 **Disco Inferno and Delinquent Students** 
 -To get the School uniforms for Jin and Xao, just play with them a lot. use 
 them something like 10 times each and you should be able to get their new uniforms. 
 I think it's the same with eddi's 70's counterpart.  
 
 **The final hidden character; Dr. B ** 
 -To get Doctor Bostonivich you must beat tekken force mode. Every time you beat
  it you will get a key. First copper, then silver then gold. The next time you beat 
 the fourth level you will face Doctor B. Beat him to add him to your list of fighters.  
 
 **Endings**
 Gun Jack, and Kuma have extendable endings. Beat the game again to get them.
