These are the listings for every challenge mission in the games, including the six that are only found in one version.

Each entry shows the area the mission is found in, the type of task performed in the mission, what type of vehicle form you are allowed to use, a description of the task, the worst observed score that will win a gold medal while playing in one player mode, and suggested strategies for getting the best score. Feel free to add your own strategies.

Note on vehicle forms

Several missions force you into a ground vehicle form, i.e. a car. If you go into the mission with an aircraft form, it will switch you to a default car for the duration of the mission. This default car is the first one you scanned in the game and has poor performance. The thing to do is quit out of the mission, switch to a car with better performance ratings, and go back in.

General tip for aircraft

It's a little counterintuitive, but it turns out that you get better speed while strafing than you do just flying straight. You can use this by turning your craft slightly to the side of where you want to go and strafe so you actually travel in the proper direction. This is somewhat trickier to do right of course, which also makes the whole thing rather annoying.
