There is one little issue with this game, the beam from one of the pods appeared just beneath the repair/refueling bay. Making me hover whenever I tried to get in it. Pods should never appear in that spot, just for the sake of gameplay. Still 5/5 to me.
How to beat Rangor: He has a longer reach than you and more powerful attacks, the proper way to hit him isn't getting head-on. Place yourself in the same spot horizontally (X axis) but distance yourself vertically (Y axis), when he walks towards you start hitting (use both A + S), once he reachs your height you will be hitting him already, pushing him back, this won't give him a chance to respond, repeat until you beat him.
How to reach 1,000 ft in the Challenge with the Hatchback (VW New Beetle):
Day 1: Max the Engine, Transmision and Wheels, buy as much fuel as possible ($760). Always accelerate, use to land always parallel to the landing surface. If everything went fine you'll earn $6200 - 6470.
Day 2: Buy the Weapon and the Boost, Max. the Fuel, use the remaining $ on Ammo. When you're on the last incline before the top of the Hill, use all your boost to reach the flat top. If everything goes fine you'll receive $12,000 - 15,500.
Day 3: Max. the Boost fuel, use the remaining $ on Ammo. Remember, use and kick ALL the Boost on the last incline, holding ->, if all goes fine, you'll get to the 1000ft or even fly above most of the crates like i did (1084ft).
Good luck!, Encho.
