Powerdrome Cheats (Xbox)

At Vehicle selection screen hold R + L triggers and press black, white, X, X, Y, and
release R + L. If you entered the code correctly, you will hear the sound of a jet taking
off.

By default the game does not let you choose the same vehicles when racing on a LAN. To
remedy this, all players must hold down the Y button before selecting the vehicle
selection screen.
