Tekken Ball
Beat the Arcade Mode with all the original characters and the 10 earnable characters.
It is basically a strange version of volleyball without a net.
Theatre mode
Unlock each character, including Panda, Tiger, Doctor Boskonovitch, and Gon, and view their endings. The "Disc" and "Sound" options under "Theatre Mode" will now be available.
Unlock Kazuya
You must have a copy of Tekken 2 before doing this. Finish Arcade mode with Jin Kazama 1000 times you should hear a noise after doing this. When you go back to character select go to the very left so the the cusor is off screen, the box will read Kazuya. If you want to use him push x, press EJECT on your Sony console and remove the Tekken 3 disc, and replace it with the Tekken 2. It will load Kazuya`s data. Now eject it and put back in Tekken 3. You can now use Kazuya. I think you can get other character`s by doing this again, maybe Devil and Jun will make an appearence...
