Hello Games' stunt driving physics-based racer, Joe Danger, is currently on sale for a buck. Or $0.99 if you want to get all official about it. What this means is that for less than the price of a cup of coffee - or just about anything, really - you can don your own flashy cape and start driving motorcycles off ramps and through flaming hoops. Well, not really, but you can in the game.
So please don't try doing any of this crazy stuff at home. That's what you have Joe Danger for!
