To get the hard badge you have to be able to fly over the boxes. 1st day buy max transmission, engine, wheels, and spend the rest on fuel. 2nd day buy gun and as much ammo as you can. 3rd day buy boost and as much boost fuel as you can - use the boost on the very last hill to fly over the boxes and get the hard badge! ++ because it works!
