Extras

Extra Weapon - Robbie Doll

In the main menu of the game (your character's bedroom) enter the Konami Code (Up, Up, Down, Down, Left, Right, Left, Right, Square, Triangle, Start) to unlock a bonus Robbie Doll weapon. After you enter the code correctly, you should hear a child's laughter. At the start of the next zone your character will get a free piece and also Robbie Dolls will become available for purchase at Howard's shop.

Bedroom's Changes

Some elements of your character's bedroom (ex. TV's splash screen) change depending on how you play the game.
