E. Gadd's Vault

The Vault is an area in Professor E. Gadd's Bunker in Luigi's Mansion: Dark Moon. Here, the player can view all of their stats in the game. The amount of gold the player has obtained will be shown on a computer monitor in the background while selecting a unit.

Ghost Container
The Ghost Container provides research information on all the ghosts Luigi has captured as well as showing a 3D model of each ghost. It also shows the highest W (Mass measurement) of the highlighted ghost the player has ever caught. Along with the number caught, however this number will never rise above 99 no matter how many have been caught.

Gem Collection
The Gem Collection lets the player view all the Gemstones they've collected throughout each mansion of the game, along with their corresponding statue if they have collected all of the crystals in the highlighted mansion.

Unlockables
The Unlockables section will display all of the upgrades Luigi received to the Poltergust 5000 and show how much gold is needed to get to the next upgrade level.

Boo Canister
The Boo Canister stores and shows all the Boos the player captured throughout each mission. It also displays the amount of Boos caught altogether.

Bank Vault
Seen within the vault is a room where the treasure gained by Luigi is stored and tallied.

Release Device
Not found in the Vault itself, this device has two buttons, one for the Ghost Container and the other for the Boo Canistor. When one of the buttons are pressed the corresponding device will release its Ghosts.
