Achievement: Tip of the WeekToday's Xbox 360 achievement tip is for Crackdown. Make your way to the supply point on the map called "Garcia Point" (second north most supply point in the Los Muertos section of Pacific City). Exit out of that supply point (or make your way there if you haven't already secured that supply point) and jump up onto the plateau just above the shack. There you should see a jeep. Get into the jeep and drive forward about a car length and drive your front wheels up on a rock. Congratulations, you've just gotten the "Driving High" achievement for 10 points!
