Cheat codes are normally only available in games on the insomnia or daydream difficulty setting. Use the following trick to use them on the nightmare or trauma difficulty setting. First, enable the desired codes in a game on the insomnia or daydream difficulty setting. Then, load a game in the menu that was played on a higher difficulty setting. The codes will remain active.
Equip the Painkiller, then hit an enemy with its second attack. Then, quickly do it three or four times while he is in the air; the enemy should not fall on ground. You will then see something like a jewel pop out. Collect it and it will add about 30 to your money.
Note: You cannot use the extra amount to get a Black Tarrot Card in Chapter 1.
