Hint: Innocent Man riddle:
One of the rooms you will enter in the Labyrinth will include six men that have been hung by the ceiling. Your job is to free the innocent man in the group. In easy riddle mode, the innocent man will always be, "The Kidnapper". In normal riddle mode, the innocent man will always be, "The Arsonist". In hard riddle mode, the innocent man will always be ,"The Counterfeiter". Once you find out who the innocent man is, pull the corresponding empty noose in the second room to release the body. In his place, the Key Of The Persecuted will be on the floor below.

Hint: Box combination:
When you get almost to the end of the hospital area and go down in the elevator, you will get a call on the radio. It is game show which will ask three questions. You must go to the third floor storeroom to get your prize. The combination to the box is 3 1 3. Note: This is for the easy and normal difficulty setting.

Hint: Defeating Eddie:
In the first battle, equip your rifle and as soon as you get the chance, shoot him four times. He will run away. Follow him into the next room. Get far away from him and just keep shooting until he dies. If he gets in close, run away and shoot him. If done correctly, he should be locked in between shots and you will not get hit.

Hint: Defeating the Doorman/Angela's Papa Boss:
Obtain the Great Knife (very big sword), in the labyrinth (from the room protected by the pyramid head enemy). Start the Boss battle by immediately pausing game play. Go to the menu and equip the Great Knife. Hold down Ready Attack before the menu screen disappears, and press Attack as hard as possible. If done correctly, you will do your fierce sword attack, and since it requires about two and a half seconds to complete by the time you swing you will have hit the Doorman. Now that it is stunned, just tap Attack to do the lesser swing and kill the Boss. If it does not, just swing the necessary amount of times, and it will die quite easily.

Hint: Defeating double pyramid head enemies:
Use the following trick for a quick and easy way to defeat the two pyramid head enemies at the end of the hotel. This will allow you to defeat them without using any health or ammunition. First, enter the room and start running around it counterclockwise. Let them get fairly close to you and then quick spin around backwards and equip the Great Knife. However, you have to make sure that James is directly next to the wall (with the wall on his left and the pyramid heads attacking from the right). Use the low swinging attack. Since James swings the knife from right to left, the knife will hit them a second time as it bounces off the wall. Keep swinging and they should not even be able to hit you.

Hint: Killing enemies:
When you encounter an enemy, try and get fairly close to it. When it attacks, quickly side step out of the way. Then, face the enemy and attack it with the board with a nail in it. Most of the early enemies you encounter have a slow reaction time after they attack and can easily be taken down with the board and nail.
Note: This is only recommended for use with those types of enemies and should not be used when facing later enemies
