Episode I Racer Glitches
This is similar to a glitch on Executioner, in which turning around on the ramp can cause the sky to appear blue. To encounter this graphical glitch, choose Vengeance, choose any pod, and then play normally until you reach the area just before the anti-gravity tube (the area you enter through a door that turns). Once in that area, stop, turn around, and come back out. A really thick blue haze, somewhat reminiscent of the underground parts in Executioner, will cover the track, making it harder to navigate.
