·  Order of tarot cards at the last door of the game

Arrange the cards as follows on the normal action and normal difficulty settings:

Northwest position: Eye Of The Night

Northeast position: Moon

West position: High Priestess

East position: Fool

South position: Hanged Man

Arrange the cards as follows on the hard difficulty setting:

Northwest position: The High Priestess

North position: The Eye Of The Night

Center position: The Fool

East position: The Moon

Southwest position: The Hanged Man

The riddle is a problem with Roman numerals. The Priestess is number II (2) as read on the book about tarots. The Eye Of The Night is XXII (22). The Fool is 0. The Moon is XVIII (18). The Hanged Man is XII (12). Look in the book of drawings to see that XVIII can stay only in the east position (the last letter is I instead of L); XII is only in the southwest position; II is only in the northwest position; 0 and XXII have two places where they can stay. Swap them until you find their correct place.

·  Defeating the last Boss with less ammunition

Equip the handgun and fire two shots. One should be fine, but fire two just in case. After Claudia bends over, equip the Maul (spiked mace) and do the overhead attack by pressing X hard. Since you will be invulnerable when Heather swings the Maul, Claudia will not hit you with her Retaliation smack. Note: Even though the swing is slow, Claudia will just wait for it.

·  Pause canceling

Almost all action scenes can be canceled (such as when you are going up or down from an elevator) with Start. However, there is a point in the final area where the lift scene can be canceled, but it will pause the game first. When you press Start again, the game will resume, but the lift scene will be canceled.
