To play as Jackal WITHOUT CODES, collect 50 coins in the Ice Camp bonus round before time runs out. The portal to the bonus round is accessed by standing in front of a star-studded door that is near the end of the Ice Camp level. (In the cargo maze near the end of the level, head to the upper-right portion of the maze and walk up the ramp. Shoot the boxes to reveal a door with a star on it. The star-studded door will transport players to a bonus level on the docks.)

Alternately, to play as Jackal WITH CODES, raise Wizard to level 10. Then, at the character selection screen, hold Turbo and choose the same character. Wizard will turn into Jackal!
