Ok, pretty simple, I need Johnny to complete my list of characters. If anyone has any advice on where i might have more chance on finding him or if anyone could clone Johnny for me.

Easy. Play Extreme Infinity Mission and watch out for the Prison Level. Go to your map, and if there is a prisoner in that level, it's a damn good chance it's Johnny.

Note, I've heard this is only do-able on Extreme and only in the Prison level.
