In the Nintendo 64 version, entering the passcode "CHICKEN" will allow the player to pilot an AT-ST in a special bonus level. However in the PC release, entering the passcode will allow the player to pilot the Walker in any of the game's missions.

It is possible to play as the Naboo Starfighter from "Episode I: The Phantom Menace" by entering the password "HALIFAX?", followed by "!YNGWIE!" (ignoring the incorrect password entry sound). The game came out six months before "The Phantom Menace" was released, so the code was kept a secret from consumers and even members of the development team. It was only after the release of the movie that the cheat's existence was made public.

The second part of the code "!YNGWIE!" was taken from musician Yngwie Malmsteen.
