Eternal Darkness

If you have a torch and you are face a large group of zombies, swing the torch at them. They will die in one hit. You will have to do a final blow quickly because they will disappear if you are too slow. Note: This will only work on the normal common zombies.

To intentionally lose your sanity, kill the servants or other people who have not been taken over by Bonethieves.

When you play as Dr. Edwin Lindsey (the archaeologist), you destroy a field blocking one of those "small dog" holes, which you find out later is a clue to the use of the Summon Trapper spell. Usually, you will pass this area and continue on, since the spell you need isn't available - not only do you not have the scroll but a rune is missing. A little bit later you will acquire the necessary rune (TIER) to complete the spell.

When you have the TIER rune, head back towards the hole and send a trapper through. You will find two horrors inside, along with a pad displaying the purple Manotorok symbol and a spider web. Placing the trapper on the pad will open a door opposite the hole, revealing the Mantorok rune. A horror will then break open the wall opening the path to the spider web which hides the Mantorok codex.

The Mantorok rune is strong against all three others, and poisons the enemy when used as a shield or enchanted weapon. It dispels all types of damage fields, although the opposing rune is still needed for Reveal Invisible. Enjoy!

Play the Fireman chapter in Eternal Mode. Pick up the rifle, select it as your weapon, and select "Mode" until there is a picture of an ammo-clip next to it. The order is one bullet, three bullets, clip, grenade rounds. Since you never lose any bullets, you can now shred enemies without prejudice by simply holding Attack. When locked-on to zombies, you can blow off all of their parts by wiggling the Analog-stick during your relentless spray of bullets. You can even keep hitting them after they fall to the ground by staying targeted on them.

Find the room with the three pictures and make sure that you have all three effigies. Put the effigies on the ledges in this order:

Warrior: Blue Effigy
Sorcerer: Green Effigy
Scholar: Red Effigy

This will open a hidden staircase in the circle room before the hallway that leads to the room you are in. Go down the stairs and you will enter a room with an Enchanted Gladius. Pick up the Gladius and complete the level as usual. When it comes time for Alex to receive the essence of whatever guardian that Mike received in his level, the Enchanted Gladius will also be in the box. This Gladius' enchantment will not run out. Use it on Pious and the battle will go much smoother than fighting him and having to re-enchant the weapon multiple times.

The easiest way to open the safe is to use the D-pad. The combination is 59 Right, 81 Left and 46 Right.

In the A War to End All Wars chapter (World War I, in the church), select either the revolver or the rifle as your weapon. Go into any room that has rats running around. Face towards the rats and press the R (aim). If one of the rats will glows white, you can shoot and kill it with your gun while targeting it. This trick works best when you have complete the game three times and can select "Eternal Mode" so that you have unlimited bullets.

With Alex, after the Peter Jacob chapter allow the game to idle at least five minutes with a low sanity level. Pious face should appear on the screen, but you will still hear the cries and laughing. Press any button and the game will return to normal.

When you run out of ammunition for any weapon, press Start, then select your gun. Select "Mix", and choose the ammunition that goes with your gun. It will be loaded without any time being wasted. This is especially useful when facing multiple enemies, as reloading is often difficult against various murderers.

Go to Options from the Main Menu to see the picture of Alex change into a skeleton.
