a little tip for all you guys with the golden gun and the tank still having trouble getting the hard badge, Dont shoot your turtle until you are slowing down. It will launch you back to max speed and max height.
How to beat 6000 feet : First, buy and max all. Then fly with am air resistance of 3% so that you gain altitude up, not down). Use your rocket till' you are at 200 in "speed". When you sink to 175, use your rockets and get back up to 200, repeat till' you run out of fuel, then let it glide. PLEASE KEEP THIS COMMENT ALIVE!!! I got the 6000 feet even without max upgrades using this guide. WORKS
