This is for clearing Arcade Battle. You play through eight stages, the last two being Heihachi/Jinpachi and Ogre, but it is easy enough and Ogre isn’t hard at all as all he does is basically stands and takes a beating. There is no difficulty options available but no one should need them, if you lose, you’ll need to have a coin handy or have a premium ticket to use, it’s just like the real arcades really, you lose, you have to insert a coin.
