Quoted from Jared:
Let me share something that will drive you nuts.
If you dont have the safecracker token... you have not played pinball.
If you ever have a chance to touch a safecracker, you owe it to yourself to not only play it, but not stop playing it until a coin comes out. This coin alone is proof of your love of pinball, and without it you are powerless.
Seek the coin.
Oh it gets worse. You need not just one coin, but the ENTIRE SET! There's twenty different ones! Muhahahahah!
