Haunting Ground Hints & Cheats

You can use these plate keys to get equippable items from the machine in the alchemy room (the room in the holes throughout the game). This machine only appears after you beat the game once.

To unlock both hard mode and the secret room beat the game once, these will then be selectable from the main menu

Towards the end of the 2nd chapter of this game (when the maid is chasing you), players will descend into a crypt where a Golem, tomb and plate machine can be found. Create a plate labeled SALTATIO and insert it into the golem for a brief, 10 second Para Para dance sequence.

Substitute "METH" for "EMETH" at the very first card slot in the game. A different cutscene will be seen, then look on the floor in front of the door and you'll find a useful Obsidian Choker.

When you first arrive at the House of Truth, go to the hallway outside Lorenzo’s Room but don’t enter his room yet. Go down the spiral staircase and collect the Golden Candlestick, then return to the 2 vases at the hallway. Kick the vase on right and a Luminescent will be free. Guild the Luminescent back to the West Garden and go down to the area where the explosive is placed. Stand on the platform under the lamp and a cutscene will play.

If you do it correctly, Lorenzo will be invisible in the cutscene. You can also bypass the old Lorenzo’s boss battle and the scene where you got trap in a room. Lorenzo will remain invisible and never chase you but this glitch will last up to the final boss battle, unless you get yourself trapped in the room. Because Lorenzo will return after the cutscene where he turns young.

Go to the Mausoleum at the Mansion's Graveyard and read the words written on the Mausoleum, the screen will darken and you won't be able to move while reading. Doing so and you will be invincible. For example, you won't feel hurt when a Luminessants hits you.

Keep reading and wait for a stalker to appear. The music will remain unchanged and the stalker can't hurt you at all. You will get panic attacks but you won't be running around like crazy. This glitch will in effect as long as the screen is darken and words are on the screen.
