E. Gadd's Vault
E. Gadd's Vault, also known as the Vault, is an area in Professor E. Gadd's Bunker in Luigi's Mansion: Dark Moon. It is available after completing the first mission in the main story mode for the first time. 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. The rising floor panel lifts Luigi back to the Bunker.
The player can earn an E. Gadd medal on their file if they complete the entire Vault: this includes collecting every Gemstone, Boo, Poltergust upgrade, and capturing every normal and boss ghost from Evershade Valley and ScareScraper at least once.
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 (Spectral Mass measurement) of the highlighted ghost the player has ever caught, along with the number caught. The number caught will never rise above 99 no matter how many of the ghost have been caught.
The Ghost Container is similar to the Containment Unit used by the Ghostbusters.
The Gem Collection lets the player view all the Gemstones they have collected throughout each mansion of the game, along with their corresponding statue if they have collected all of the crystals in the highlighted mansion.
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.
The Boo Canister stores and shows all the Boos the player captured throughout each mission. It also displays the amount of Boos caught altogether.
Even when the player has defeated King Boo, he will not appear in the Boo Canister.
Seen within the vault is a room where the treasure gained by Luigi is stored and tallied.
Not found in the Vault itself, it is a yellow remote with a single antenna and two red buttons, one for the Ghost Container and the other for the Boo Canister. When one of the buttons is pressed, the corresponding device will release its Ghosts. It is only seen in the epilogue, where E. Gadd holds it out in his hand.
